+# PACKAGING WORKFLOW(S)
+
+The qemu package follows a special maintenance workflow in order to support
+git based patching, including of submodules. Please use it in order to have
+changes you make be acceptable to the package maintainers.
+
+All the development happens at https://github.com/openSUSE/qemu. The relevant
+branch is `factory`.
+
+Any change to the package should be submitted in the form of a Pull Request
+against such repository and branch.
+
+The reminder of this document provides more details, explanations and examples
+for both contributors and maintainers.
+
+
+# FOR CONTRIBUTORS
+
+## BACKPORTING AN UPSTREAM PATCH
+
+For submitting a backport of an upstream patch, proceed as follows (a local
+copy of the repository is of course necessary).
+
+Identify the hash of the commit that needs backporting and do:
+
+  git cherry-pick -esx <commit_hash>
+
+This way, the changelog will already contain the reference to the upstream
+commit itself, and the appropriate "Signed-off-by:" tag.
+
+If the backport is related to Bugzilla (or Jira, and/or CVEs, etc) entry, add a
+reference to that, such as:
+
+  Resolves: bsc#123456
+
+Or:
+
+  References: jsc#PED-1234
+
+Or:
+
+  Resolves: bsc#7891011 (CVE-1234-5678)
+
+Add it between the "(cherry picked from commit ...)" line and the "Signed-off-by:"
+line that follows it.
+
+An example of the end result, where Dario Faggioli (<dfaggioli@suse.com>) is
+backporting upstream commit abe2c4bdb65e8dd in order to fix bug 1209546 from
+bugzilla.opensuse.org is:
+
+    test-vmstate: fix bad GTree usage, use-after-free
+    
+    According to g_tree_foreach() documentation:
+    "The tree may not be modified while iterating over it (you can't
+    add/remove items)."
+    
+    [...]
+    
+    Get rid of the node removal within the tree traversal. Also
+    check the trees have the same number of nodes before the actual
+    diff.
+    
+    Fixes: 9a85e4b8f6 ("migration: Support gtree migration")
+    Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1518
+    Signed-off-by: Marc-Andr303251 Lureau <marcandre.lureau@redhat.com>
+    Signed-off-by: Eric Auger <eric.auger@redhat.com>
+    Reported-by: Richard W.M. Jones <rjones@redhat.com>
+    Tested-by: Richard W.M. Jones <rjones@redhat.com>
+    Reviewed-by: Richard W.M. Jones <rjones@redhat.com>
+    Reviewed-by: Daniel P. Berrang303251 <berrange@redhat.com>
+    Reviewed-by: Juan Quintela <quintela@redhat.com>
+    Signed-off-by: Juan Quintela <quintela@redhat.com>
+    (cherry picked from commit abe2c4bdb65e8dd9cb2f01c355baa394bf49a8af)
+    Resolves: bsc#1209546
+    Signed-off-by: Dario Faggioli <dfaggioli@suse.com>
+
+Of course, all conflicts and issues should be resolved, before committing the
+result/completing the cherry-picking.
+
+At this point, the PR should be opened. As soon as that happens, some checks
+will be run automatically and the maintainers of the QEMU package will review
+and, eventually, merge or reject it.
+
+PRs containing multiple commits are allowed. They are actually encouraged, if
+the patches being backported are related and/or dependant among each others. It
+must, however, always be the case that each upstream commit is cherry-picked
+individually.
+
+Note that there is no need to change any 'qemu.changes' file. That will, in
+fact be handled by the package maintainers (and such RPM changelog entries will
+be automatically generated out of the git commit messages).
+
+## ADDING A PATCH NOT COMING FROM UPSTREAM
+
+Downstream patches, i.e., patches that are not backports of upstream commits,
+should be avoided as much as possible. The (largely!) recommended approach is
+to submit the patch upstream and then, once it is accepted and committed,
+backport it.
+
+If that is not possible (for whatever reason), a pull request with a downstream
+only patch can be opened. The procedure is almost identical to the one described
+above for upstream backports. The main differences are:
+
+1) Downstream only patch cannot be cherry-picked from upstream commits, of
+   course. Therefore, the PR will consist of the commit(s) that introduces the
+   patch.
+ 
+2) There will be no "(cherry picked from commit ...") line in the changelog
+   of a downstream only patch. On the other hand, the "Resolves:" or
+   "Reference:" tag, that link the patch to the issue it's trying to solve,
+   must be there, and the same is true for the "Signed-off-by:" tag
+   indicating who is proposing adding it.
+
+3) It is required that the subject of the commit starts with the [openSUSE] tag.
+
+An example of a downstream only commit is:
+
+    [openSUSE] pc: q35: Bump max_cpus to 1024
+    
+    And use the new limit for machine version 7.1 too.
+    Keep the old limit of 288 for machine versions 7.0 and earlier.
+    
+    Signed-off-by: Dario Faggioli <dfaggioli@suse.com>
+    References: bsc#1202282, jsc#PED-2592
+    Signed-off-by: Dario Faggioli <dfaggioli@suse.com>
+
+## CHANGING THE PACKAGING FILES
+
+Files that are necessary for building the RPM (like the spec file) or that
+are part of the RPM and will be copied in the appropriate places in the
+filesystem when it is installed are also part of the git repository. In fact,
+they can be found in the `rpm/` directory.
+
+Any addition, removal or change of and on any of those file should just be done
+as a regular commit, and a pull request including such commit(s) should be
+opened.
+
+Commits to packaging files should be prefixed with both the [openSUSE] tag and
+an [RPM] tag. An example can be this one:
+
+    [openSUSE][RPM] Add downstream packaging files
+    
+    Stash the "packaging files" in the QEMU repository, in the rpm/
+    directory. During package build, they will be pulled out from there
+    and used as appropriate.
+    
+    Signed-off-by: Dario Faggioli <dfaggioli@suse.com>
+
+## ADDING A PATCH IN A SUBMODULE
+
+For including a backport, or in general adding a patch, to a submodule, the
+downstream git repository for the submodule must be checkedout at the location
+where the submodule resides, in the main QEMU git repository.
+
+For example, for including a downstream patch in the ipxe submodule, a local
+copy of the repository https://github.com/openSUSE/qemu-ipxe.git is necessary.
+After checking out the `factory` branch, add the patch there (cherry-picking
+it from upstream, if it is a backport, and respecting all the tagging rules
+explained in the previous sections).
+
+At this point:
+- the branch must be pushed;
+- in the main (qemu) repository, a commit must be added and pushed, for making
+  sure that the new patch is picked up.
+
+Basically, the commit in the main repository is how the information that a
+submodule as a new head is recorded.
+
+The changelog of such commit shall include a reference to the subjects of all
+the new commits in the various submodules. Unfortinately, there is not yet a
+good way of achieving this automatically.
+
+As last step, a pull request should be opened, as usual.
+
+## REMOVING PATCHES
+
+If a patch, or, in general, a commit, that is already part of the repository
+must be removed, this must be done without rewriting the git history, i.e., with
+a revert (and then a pull request with the revert should be opened).

+SLES 15 SP4 QEMU/KVM RELATED SUPPORT STATEMENTS
+===============================================
+
+Overview
+--------
+
+  The QEMU based packages included with SLES 15 SP4 provide a large variety of
+  features, from the very latest customer requests to features of questionable
+  quality or value. The linux kernel includes components which contribute KVM
+  virtualization features as well. This document was created to assist the user
+  in deciding which features can be relied upon to build enterprise class
+  virtualization solutions. KVM based virtualization for x86 (Intel 64/AMD64),
+  for IBM System z (s390x), and for the ARM64 architecture (AArch64) are offered
+  at the L3 (full support) level. The bulk of this document deals with L3
+  supported features and is primarily ARM64 centric. This document should be
+  considered a companion to the standard virtualization documentation delivered
+  with the product.
+
+  KVM is implemented in linux kernel modules which enable the linux kernel to
+  function as an integral part of the KVM hypervisor. The hypervisor-guest
+  interaction is managed by QEMU through the /dev/kvm ioctl interface. The linux
+  host assists in the virtualization of storage, networking and display
+  resources as well as allowing direct hardware passthrough of PCI and USB
+  devices. Linux memory and cpu management features are used by QEMU/KVM to
+  enable guests to share those host resources as efficiently as possible.
+
+  QEMU is a primary component of KVM based virtualization. The QEMU emulator
+  binary qemu-system-aarch64 is the program to use to access KVM virtualization.
+  When using this program, the -machine option accel=kvm (or its alias
+  -enable-kvm) or --accel kvm option must be specified for KVM acceleration to
+  be used by the guest.
+
+  Libvirt is the preferred means of accessing QEMU/KVM functionality and is
+  documented elsewhere. This document focuses on the features and direct usage
+  of QEMU/KVM as provided by the QEMU based packages.
+
+Major QEMU/KVM Supported Features
+---------------------------------
+
+- KVM virtualization is accomplished by using the QEMU program in KVM
+  acceleration mode. KVM acceleration requires that both guest and host have
+  the same fundamental architecture.
+
+- Guest images created under previous QEMU versions are supported by machine
+  version compatibilities built into more recent QEMU versions.
+
+- For ease of use, the QEMU program has defaults which represent traditional
+  usage patterns.
+
+- Guest virtual machine characteristics are specified by a combination of
+  internal defaults, options provided on the QEMU program command-line, runtime
+  configurations set via the monitor interfaces and optional config files. The
+  runtime control of a VM is effected either through the Human Monitor
+  "Protocol" (HMP), or the JSON based programmatical QEMU Monitor Protocol (QMP)
+  interface. For QMP details, see qemu-qmp-ref man page.
+  Since a KVM guest runs in the context of a normal linux process, some types
+  of execution controls are managed with linux tools.
+
+- QEMU is compatible with EDK II based UEFI firmware available with SLES 15 SP4,
+  which allow boot options common to physical systems, along with other features
+  tailored to virtualization. Various VGABIOS ROMs, from the SEABIOS project,
+  are also available.
+
+- Some QEMU messages have been localized to various languages. This is provided
+  by the optional qemu-lang package. Keyboard mappings for various nationalities
+  is also provided.
+
+- Virtual machine lifecycle controls include startup through the UEFI BIOS or
+  kernel boot, ACPI based shutdown, execution pausing, the saving and restoring
+  of machine state or disk state, VM migration to another host, and
+  miscellaneous controls available through the "monitors" mentioned above.
+
+- Guest execution state may be "moved" in both time (save/restore) and space
+  (static and live migration). These migrations or save/restore operations can
+  take place either from certain prior SLES versioned hosts to a SLES 15 SP4
+  host or between hosts of the same version. Certain other restrictions also
+  apply.
+
+- Security considerations include privileged helpers and a security model which
+  allows running guests as a non-root user.
+
+- QEMU provides best effort reuse of existing disk images, including those with
+  systems installed, through geometry probing. Also disk images produced by
+  other popular virtualization technologies may be imported into QEMU supported
+  storage formats. These QEMU formats include features which exploit the
+  benefits of virtualization.
+
+- Memory, cpu and disk space overcommit are possible and can be beneficial when
+  done responsibly. Additional management of these resources comes in the form
+  of memory ballooning or hotplug, host KSM, vcpu hot-add, online disk resizing,
+  trim, discard and hole punching.
+
+- Guest performance is enhanced through the use of virtio devices, various disk
+  caching modes, network acceleration via the vhost-net kernel module, multi-
+  queue network transmit capabilities, host transparent huge pages (THP) and
+  direct hugetlb usage. Physical PCI and USB devices may also be passed through
+  to the guest, including SR-IOV VF's.
+
+- The guest UI is accessable via GTK, VNC, Spice, and serial (including curses
+  TUI) interfaces.
+
+- Guest timekeeping is supported in a variety of ways, including a paravirtual
+  clocksource, and options for the various guest clocks for how to handle the
+  timeslicing of the guest's execution on the host.
+
+- In addition to the para-virtualized devices already mentioned, other devices
+  and infrastructure designed to avoid virtualization "problem areas" are
+  available such as SPICE graphics, vmmouse emulation, tablet style pointer
+  interfaces and virtio based UI interfaces.
+
+- A built-in user-mode network (SLIRP) stack is available.
+
+- Portions of the host file system may be shared with a guest by using virtFS.
+
+- A guest "agent" is available for SLES 15 SP4 KVM guests via the
+  qemu-guest-agent package. This allows some introspection and control of the
+  guest OS environment from the host.
+
+QEMU/KVM Technology Previews
+----------------------------
+
+- All features indicated as not being supported in this document fall under the
+  Technology Preview definition contained in the main product's release notes.
+
+Noteworthy QEMU/KVM Unsupported Features
+----------------------------------------
+
+- Note that some features are unsupported simply due to lack of validation. If
+  an existing feature is desired, but not marked supported, let SUSE know about
+  your requirements.
+
+- The TCG "acceleration" mode may be helpful for problem isolation, but
+  otherwise presents insufficient benefit and stability.
+
+- GlusterFS integration is not enabled.
+
+- 32 bit ARM KVM has never been supported by SUSE, but it's worth noting that
+  this capability will cease to even be possible in a near-future QEMU/KVM
+  (kernel) combination.
+
+Deprecated, Superseded, Modified and Dropped Features
+-----------------------------------------------------
+
+- https://qemu-project.gitlab.io/qemu/about/deprecated.html and
+  https://qemu-project.gitlab.io/qemu/about/removed-features.html
+  These websites track features deprecation and removal at the upstream
+  development level. Our qemu package inherits this community direction, but be
+  aware that we can and will deviate as needed. Those deviations and additional
+  information can be found in this section. Feature deprecation as well as
+  removed features are also tracked in the "System Emulation" section of the
+  documentation installed with the qemu package.
+
+- qemu-img: Deprecate use of -b without -F. Creating an image that requires
+  format probing of the backing image is potentially unsafe and is now
+  deprecated.
+
+- Aspeed swift-bmc machine is deprecated. It can be easily replaced by the
+  witherspoon-bmc or the romulus-bmc machines.
+
+- The previously non-persistent backing file with pmem=on is deprecated. Modify
+  VM configuration to set pmem=off to continue using fake NVDIMM with backing
+  file or move backing file to NVDIMM storage and keep pmem=on.
+
+- The use of "?" as a parameter to "-cpu", "-soundhw", "-device", "-M",
+  "-machine" and "-d" is now considered deprecated. Use "help"
+  instead.
+
+- The use of "if=scsi" as a parameter to "-drive" does not work anymore with PC
+  machine types, as it created an obsolete SCSI controller model.
+
+- Use of aio=native without direct cache mode also being specified (cache=none,
+  cache=directsync, or cache.direct=on) is no longer allowed.
+
+- The use of image encryption in qcow and qcow2 formats is now considered
+  deprecated.
+  Analysis has shown it to be weak encryption, in addition to suffering from
+  poor design. Images can easily be converted to a non-encrypted format.
+
+- Use of acpi, boot-opts, and smp-opts in a -readconfig config file are now
+  considered deprecated. In the future those names will be standardized to
+  acpitable, boot, and smp respectively.
+
+- These previously supported command line options are now considered deprecated:
+  -display sdl,window_close= (use -display sdl,window-close)
+  -no-quit (use -display ...,window-close=off)
+  -chardev tty (use serial name instead)
+  -chardev paraport (use parallel name instead)
+  -device virtio-blk,scsi= (use virtio-scsi instead)
+  -device virtio-blk-pci,scsi= (use virtio-scsi instead)
+  -enable-fips (not really helpful - see https://git.qemu.org/?p=qemu.git;a=commit;h=166310299a1e7824bbff17e1f016659d18b4a559 for details)
+  -realtime mlock= (use -overcommit mem-lock= instead)
+  -spice password=string (use password-string option instead)
+  -writeconfig (no replacement - never really worked right)
+  -share and noshare must be replaced by share=on/share=off
+  -nodelay must be replaced by nodelay=on rather than delay=off
+  -object-add options opened=on and loaded=on (both had no effect)
+
+- These previously supported command line options are no longer supported:
+  -device ide-drive (use ide-hd or ide-cd instead)
+  -device scsi-disk (use scsi-hd or scsi-cd instead)
+
+- These previously supported command line options are no longer recognized:
+  -balloon (use -device virtio-balloon instead)
+  -clock
+  -device ivshmem (use ivshmem-doorbell or ivshmem-plain instead)
+  -device pc-sysfw (no longer needed)
+  -device pci-assign, -device kvm-pci-assign (use -device vfio-pci instead)
+  -display sdl
+  -no-frame
+  -nodefconfig (use -no-user-config instead)
+  -realtime ...
+  -sdl
+  -show-cursor
+  -virtioconsole (use -device virtconsole instead)
+
+- The previously unsupported machine type xlnx-ep108 is no longer recognized
+  (used xlnx-zcu102 unstead)
+
+- Specifying a cpu feature with both "+feature/-feature" and "feature=on/off"
+  will now cause a warning. The current behavior for this combination where
+  "+feature/-feature" wins over "feature=on/off", will be changed going forward
+  so that "+feature" and "-feature" will be synonyms for "feature=on" and
+  "feature=off" respectively.
+
+- The previously supported blkdev-add QMP command has been flagged as lacking
+  and could possibly change syntax in the future.
+
+- This previously unsupported command line option is now deprecated:
+  -soundhw (use -device ... instead)
+
+- These previously unsupported command line options are no longer recognized:
+  -bt
+  -device at24c-eeprom
+  -device mmio_interface
+  -device ssi-sd
+  -device tpm-tis-device
+  -device u2f-passthru
+  -device vhost-user-vsock-pci-transitional
+  -device vhost-vsock-pci-transitional
+  -device virtio-iommu-pci-transitional
+  -enable-hax
+  -tb-size
+  -tdf
+  -xen-create
+
+- These previously supported QMP commands are now deprecated:
+  <previously mentioned items have been moved to another category>
+
+- These previously supported QMP commands are no longer recognized:
+  info cpustats
+  block_passwd
+  change (use blockdev-change-medium or change-vnc-password instead)
+  cpu-add (use device_add instead)
+  migrate-set-cache-size (use migrate-set-parameters instead)
+  migrate_set_downtime (use migrate-set-parameters instead)
+  migrate_set_speed (use migrate-set-parameters instead)
+  query-cpus (use query-cpus-fast instead)
+  query-events
+  query-migrate-cache-size (use query-migrate-parameters instead)
+
+- These previously supported monitor commands are now deprecated:
+  change
+
+- These previously supported monitor commands are no longer recognized:
+  info cpustats
+  block_passwd ...
+  cpu-add (use device_add instead)
+  migrate_set_cache_size
+  migrate_set_downtime
+  migrate_set_speed
+  pci_add (use device_add instead)
+  pci_del (use device_del instead)
+  usb_add (use device_add instead)
+  usb_del (use device_del instead)
+
+- These previously unsupported monitor command are now deprecated:
+  <previously mentioned items have been moved to another category>
+
+- These previously unsupported monitor commands are no longer recognized:
+  acl_add ...
+  acl_policy ...
+  acl_remove ...
+  acl_reset ...
+  acl_show ...
+  host_net_add
+  host_net_remove
+
+- These previously unsupported QMP commands are now supported under a new name:
+  x-block-dirty-bitmap-disable (use block-dirty-bitmap-disable instead)
+  x-block-dirty-bitmap-enable (use block-dirty-bitmap-enable instead)
+  x-block-dirty-bitmap-merge (use block-dirty-bitmap-merge instead)
+  x-block-latency-histogram-set (use block-latency-histogram-set instead)
+  x-blockdev-create (use blockdev-create instead)
+
+- This previously unsupported QMP commands is no longer recognized:
+  x-nbd-server-add-bitmap
+
+- Due to upstream's decision to no longer fully support the qed storage format
+  going forward (since it really provides no benefit over qcow2 and is now no
+  longer actively maintained upstream), creating qed storage images is no longer
+  supported and it is highly discouraged to continue using existing qed images.
+  They should instead be converted to another supported format.
+
+QEMU Command-Line and Monitor Syntax and Support
+------------------------------------------------
+
+- The QEMU program command-line syntax is as follows:
+  qemu-system-aarch64 [options]
+
+  Where 'options' are taken from the options listed below.
+  The images used with -drive or -cdrom, may be in the raw (no format) or qcow2
+  storage formats, and may be located in files within the host filesystem,
+  logical volumes, host physical disks, or network based storage. Read only
+  media may also be accessed via URL style protocol specifiers.
+
+  Note that as a general rule, as new command line options are added which serve
+  to replace an older option or interface, you are strongly encouraged to adapt
+  your usage to the new option. The new option is being introduced to provide
+  better functionality and usability going forward. In some cases existing
+  problems or even bugs in older interfaces cannot be fixed due to functional
+  expectations, but are resolved in the newer interface or option.
+  This advice includes moving to the most recent machine type (eg virt-6.1
+  instead of virt-6.0) if possible.
+
+- The following command line options are supported:
+  -accel ...
+  -action ...
+  -add-fd ...
+  -alt-grab
+  -append ...
+  -audio-help
+  -audiodev
+  -bios ...
+  -blockdev ...

+  -chardev ...
+  -compat ...
+  -cpu host

+SLES 15 SP4 QEMU/KVM RELATED SUPPORT STATEMENTS
+===============================================
+
+Overview
+--------
+
+  The QEMU based packages included with SLES 15 SP4 provide a large variety of
+  features, from the very latest customer requests to features of questionable
+  quality or value. The linux kernel includes components which contribute KVM
+  virtualization features as well. This document was created to assist the user
+  in deciding which features can be relied upon to build enterprise class
+  virtualization solutions. KVM based virtualization for x86 (Intel 64/AMD64),
+  for IBM System z (s390x), and for the ARM64 architecture (AArch64) are offered
+  at the L3 (full support) level. The bulk of this document deals with L3
+  supported features and is primarily s390x centric. This document should be
+  considered a companion to the standard virtualization documentation delivered
+  with the product.
+
+  KVM is implemented in linux kernel modules which enable the linux kernel to
+  function as an integral part of the KVM hypervisor. The hypervisor-guest
+  interaction is managed by QEMU through the /dev/kvm ioctl interface. The linux
+  host assists in the virtualization of storage, networking and display
+  resources as well as allowing direct hardware passthrough of PCI devices.
+  Linux memory and cpu management features are used by QEMU/KVM to enable guests
+  to share those host resources as efficiently as possible.
+
+  QEMU is a primary component of KVM based virtualization. The legacy qemu-kvm
+  program is available for continuity with pre SLES 12 usage, including in
+  libvirt domain xml references. The QEMU emulator binary qemu-system-s390x is
+  now the primary program to use to access KVM virtualization. When using this
+  program, the -machine option accel=kvm (or its alias -enable-kvm) or --accel
+  kvm option must be specified for KVM acceleration to be used by the guest.
+
+  Libvirt is the preferred means of accessing QEMU/KVM functionality and is
+  documented elsewhere. This document focuses on the features and direct usage
+  of QEMU/KVM as provided by the QEMU based packages.
+
+Major QEMU/KVM Supported Features
+---------------------------------
+
+- KVM virtualization is accomplished by using the QEMU program in KVM
+  acceleration mode. KVM acceleration requires that both guest and host have
+  the same fundamental architecture.
+
+- Guest images created under previous QEMU versions are supported by machine
+  version compatibilities built into more recent QEMU versions.
+
+- For ease of use, the QEMU program has defaults which represent traditional
+  usage patterns.
+
+- Guest virtual machine characteristics are specified by a combination of
+  internal defaults, options provided on the QEMU program command-line, runtime
+  configurations set via the monitor interfaces and optional config files. The
+  runtime control of a VM is effected either through the Human Monitor
+  "Protocol" (HMP), or the JSON based programmatical QEMU Monitor Protocol (QMP)
+  interface. For QMP details, see qemu-qmp-ref man page.
+  Since a KVM guest runs in the context of a normal linux process, some types
+  of execution controls are managed with linux tools.
+
+- QEMU incorporates virtualized, s390 specific, ccw bus based firmware for
+  booting s390 guests. This firmware is automatically incorporated and
+  doesn't need to be explicitly referenced.
+
+- Some QEMU messages have been localized to various languages. This is provided
+  by the optional qemu-lang package. Keyboard mappings for various nationalities
+  is also provided.
+
+- Virtual machine lifecycle controls include startup through the ccw firmware or
+  kernel boot, firmware based shutdown, execution pausing, the saving and
+  restoring of machine state or disk state, VM migration to another host, and
+  miscellaneous controls available through the "monitors" mentioned above.
+
+- Guest execution state may be "moved" in both time (save/restore) and space
+  (static and live migration). These migrations or save/restore operations can
+  take place either from certain prior SLES versioned hosts to a SLES 15 SP4
+  host or between hosts of the same version. Certain other restrictions also
+  apply.
+
+- Security considerations include privileged helpers and a security model which
+  allows running guests as a non-root user.
+
+- QEMU provides best effort reuse of existing disk images, including those with
+  systems installed, through geometry probing. Also disk images produced by
+  other popular virtualization technologies may be imported into QEMU supported
+  storage formats. These QEMU formats include features which exploit the
+  benefits of virtualization.
+
+- Memory, cpu and disk space overcommit are possible and can be beneficial when
+  done responsibly. Additional management of these resources comes in the form
+  of memory ballooning or hotplug, host KSM, vcpu hot-add, online disk resizing,
+  trim, discard and hole punching.
+
+- Guest performance is enhanced through the use of virtio devices, various disk
+  caching modes, network acceleration via the vhost-net kernel module, multi-
+  queue network transmit capabilities, host transparent huge pages (THP) and
+  direct hugetlb usage. Physical PCI devices may also be passed through to the
+  guest, including SR-IOV VF's.
+
+- The guest UI is accessable via GTK, VNC, and serial (including curses TUI)
+  interfaces.
+
+- Guest timekeeping is supported in a variety of ways, including a paravirtual
+  clocksource, and options for the various guest clocks for how to handle the
+  timeslicing of the guest's execution on the host.
+
+- In addition to the para-virtualized devices already mentioned, other devices
+  and infrastructure designed to avoid virtualization "problem areas" are
+  available such as SPICE graphics, vmmouse emulation, tablet style pointer
+  interfaces and virtio based UI interfaces.
+
+- A built-in user-mode network (SLIRP) stack is available.
+
+- Portions of the host file system may be shared with a guest by using virtFS.
+
+- A guest "agent" is available for SLES 15 SP4 KVM guests via the
+  qemu-guest-agent package. This allows some introspection and control of the
+  guest OS environment from the host.
+
+QEMU/KVM Technology Previews
+----------------------------
+
+- All features indicated as not being supported in this document fall under the
+  Technology Preview definition contained in the main product's release notes.
+
+Noteworthy QEMU/KVM Unsupported Features
+----------------------------------------
+
+- Note that some features are unsupported simply due to lack of validation. If
+  an existing feature is desired, but not marked supported, let SUSE know about
+  your requirements.
+
+- The TCG "acceleration" mode may be helpful for problem isolation, but
+  otherwise presents insufficient benefit and stability.
+
+- GlusterFS integration is not enabled.
+
+Deprecated, Superseded, Modified and Dropped Features
+-----------------------------------------------------
+
+- https://qemu-project.gitlab.io/qemu/about/deprecated.html and
+  https://qemu-project.gitlab.io/qemu/about/removed-features.html
+  These websites track features deprecation and removal at the upstream
+  development level. Our qemu package inherits this community direction, but be
+  aware that we can and will deviate as needed. Those deviations and additional
+  information can be found in this section. Feature deprecation as well as
+  removed features are also tracked in the "System Emulation" section of the
+  documentation installed with the qemu package.
+
+- qemu-img: Deprecate use of -b without -F. Creating an image that requires
+  format probing of the backing image is potentially unsafe and is now
+  deprecated.
+
+- The previously non-persistent backing file with pmem=on is deprecated. Modify
+  VM configuration to set pmem=off to continue using fake NVDIMM with backing
+  file or move backing file to NVDIMM storage and keep pmem=on.
+
+- The use of "?" as a parameter to "-cpu", "-soundhw", "-device", "-M",
+  "-machine" and "-d" is now considered deprecated. Use "help"
+  instead.
+
+- The use of "if=scsi" as a parameter to "-drive" does not work anymore with PC
+  machine types, as it created an obsolete SCSI controller model.
+
+- Use of aio=native without direct cache mode also being specified (cache=none,
+  cache=directsync, or cache.direct=on) is no longer allowed.
+
+- The use of image encryption in qcow and qcow2 formats is now considered
+  deprecated.
+  Analysis has shown it to be weak encryption, in addition to suffering from
+  poor design. Images can easily be converted to a non-encrypted format.
+
+- Use of acpi, boot-opts, and smp-opts in a -readconfig config file are now
+  considered deprecated. In the future those names will be standardized to
+  acpitable, boot, and smp respectively.
+
+- These previously supported command line options are now considered deprecated:
+  -display sdl,window_close= (use -display sdl,window-close)
+  -no-quit (use -display ...,window-close=off)
+  -chardev tty (use serial name instead)
+  -chardev paraport (use parallel name instead)
+  -device virtio-blk,scsi= (use virtio-scsi instead)
+  -device virtio-blk-pci,scsi= (use virtio-scsi instead)
+  -enable-fips (not really helpful - see https://git.qemu.org/?p=qemu.git;a=commit;h=166310299a1e7824bbff17e1f016659d18b4a559 for details)
+  -realtime mlock= (use -overcommit mem-lock= instead)
+  -spice password=string (use password-string option instead)
+  -writeconfig (no replacement - never really worked right)
+  -share and noshare must be replaced by share=on/share=off
+  -nodelay must be replaced by nodelay=on rather than delay=off
+  -object-add options opened=on and loaded=on (both had no effect)
+
+- These previously supported command line options are no longer supported:
+  <previously mentioned items have been moved to another category>
+
+- These previously supported command line options are no longer recognized:
+  -balloon (use -device virtio-balloon instead)
+  -clock
+  -device ivshmem (use ivshmem-doorbell or ivshmem-plain instead)
+  -device pc-sysfw (no longer needed)
+  -device pci-assign, -device kvm-pci-assign (use -device vfio-pci instead)
+  -display sdl
+  -no-frame
+  -nodefconfig (use -no-user-config instead)
+  -realtime ...
+  -sdl
+  -show-cursor
+  -virtioconsole (use -device virtconsole instead)
+
+- Specifying a cpu feature with both "+feature/-feature" and "feature=on/off"
+  will now cause a warning. The current behavior for this combination where
+  "+feature/-feature" wins over "feature=on/off", will be changed going forward
+  so that "+feature" and "-feature" will be synonyms for "feature=on" and
+  "feature=off" respectively.
+
+- The previously supported blkdev-add QMP command has been flagged as lacking
+  and could possibly change syntax in the future.
+
+- These previously unsupported command line options are now deprecated:
+  -bt
+  -soundhw (use -device ... instead)
+
+- These previously unsupported command line options are no longer recognized:
+  -device ide-drive (use ide-hd or ide-cd)
+  -device mmio_interface
+  -device ramfb
+  -device scsi-disk (use scsi-hd or scsi-cd)
+  -device vhost-user-vsock-pci-transitional
+  -device vhost-vsock-pci-transitional
+  -device virtio-iommu-pci-transitional
+  -enable-hax
+  -tb-size
+  -tdf
+  -xen-create
+
+- These previously supported QMP commands are now deprecated:
+  <previously mentioned items have been moved to another category>
+
+- These previously supported QMP commands are no longer recognized:
+  info cpustats
+  block_passwd
+  change (use blockdev-change-medium or change-vnc-password instead)
+  cpu-add (use device_add instead)
+  migrate-set-cache-size (use migrate-set-parameters instead)
+  migrate_set_downtime (use migrate-set-parameters instead)
+  migrate_set_speed (use migrate-set-parameters instead)
+  query-cpus (use query-cpus-fast instead)
+  query-events
+  query-migrate-cache-size (use query-migrate-parameters instead)
+
+- These previously supported monitor commands are now deprecated:
+  change
+
+- These previously supported monitor commands are no longer recognized:
+  info cpustats
+  block_passwd ...
+  cpu-add (use device_add instead)
+  migrate_set_cache_size
+  migrate_set_downtime
+  migrate_set_speed
+  pci_add (use device_add instead)
+  pci_del (use device_del instead)
+
+- These previously unsupported monitor command are now deprecated:
+  <previously mentioned items have been moved to another category>
+
+- These previously unsupported monitor commands are no longer recognized:
+  acl_add ...
+  acl_policy ...
+  acl_remove ...
+  acl_reset ...
+  acl_show ...
+  host_net_add
+  host_net_remove
+  usb_add
+  usb_del
+
+- These previously unsupported QMP commands are now supported under a new name:
+  x-block-dirty-bitmap-disable (use block-dirty-bitmap-disable instead)
+  x-block-dirty-bitmap-enable (use block-dirty-bitmap-enable instead)
+  x-block-dirty-bitmap-merge (use block-dirty-bitmap-merge instead)
+  x-block-latency-histogram-set (use block-latency-histogram-set instead)
+  x-blockdev-create (use blockdev-create instead)
+
+- This previously unsupported QMP commands is no longer recognized:
+  x-nbd-server-add-bitmap
+
+- Due to upstream's decision to no longer fully support the qed storage format
+  going forward (since it really provides no benefit over qcow2 and is now no
+  longer actively maintained upstream), creating qed storage images is no longer
+  supported and it is highly discouraged to continue using existing qed images.
+  They should instead be converted to another supported format.
+
+QEMU Command-Line and Monitor Syntax and Support
+------------------------------------------------
+
+- The QEMU program command-line syntax is as follows:
+  qemu-system-s390x [options]
+
+  Where 'options' are taken from the options listed below.
+  The images used with -drive or -cdrom, may be in the raw (no format) or qcow2
+  storage formats, and may be located in files within the host filesystem,
+  logical volumes, host physical disks, or network based storage. Read only
+  media may also be accessed via URL style protocol specifiers.
+
+  Note that as a general rule, as new command line options are added which serve
+  to replace an older option or interface, you are strongly encouraged to adapt
+  your usage to the new option. The new option is being introduced to provide
+  better functionality and usability going forward. In some cases existing
+  problems or even bugs in older interfaces cannot be fixed due to functional
+  expectations, but are resolved in the newer interface or option.
+  This advice includes moving to the most recent machine type (eg
+  s390-ccw-virtio-6.1 instead of s390-ccw-virtio-6.0) if possible.
+
+- The following command line options are supported:
+  -accel ...
+  -action ...
+  -add-fd ...
+  -alt-grab
+  -append ...
+  -audio-help
+  -audiodev
+  -bios ...

+  -chardev ...
+  -compat ...
+  -cpu host
+  -ctrl-grab

+SLES 15 SP4 QEMU/KVM RELATED SUPPORT STATEMENTS
+===============================================
+
+Overview
+--------
+
+  The QEMU based packages included with SLES 15 SP4 provide a large variety of
+  features, from the very latest customer requests to features of questionable
+  quality or value. The linux kernel includes components which contribute KVM
+  virtualization features as well. This document was created to assist the user
+  in deciding which features can be relied upon to build enterprise class
+  virtualization solutions. KVM based virtualization for x86 (Intel 64/AMD64),
+  for IBM System z (s390x), and for the ARM64 architecture (AArch64) are offered
+  at the L3 (full support) level. The bulk of this document deals with L3
+  supported features and is primarily x86 centric. This document should be
+  considered a companion to the standard virtualization documentation delivered
+  with the product.
+
+  KVM is implemented in linux kernel modules which enable the linux kernel to
+  function as an integral part of the KVM hypervisor. The hypervisor-guest
+  interaction is managed by QEMU through the /dev/kvm ioctl interface. The linux
+  host assists in the virtualization of storage, networking and display
+  resources as well as allowing direct hardware passthrough of PCI and USB
+  devices. Linux memory and cpu management features are used by QEMU/KVM to
+  enable guests to share those host resources as efficiently as possible.
+
+  QEMU is a primary component of KVM based virtualization. The legacy qemu-kvm
+  program is available for continuity with pre SLES 12 usage, including in
+  libvirt domain xml references. The QEMU emulator binaries qemu-system-x86_64
+  and qemu-system-i386 (x86 host) are now the primary programs to use to access
+  KVM virtualization. When using these programs, the -machine option accel=kvm
+  (or its alias -enable-kvm), or --accel kvm option must be specified for KVM
+  acceleration to be used by the guest. Although Xen uses QEMU for
+  virtualization as well, this document does not identify Xen supported
+  features.
+
+  Libvirt is the preferred means of accessing QEMU/KVM functionality and is
+  documented elsewhere. This document focuses on the features and direct usage
+  of QEMU/KVM as provided by the QEMU based packages.
+
+Major QEMU/KVM Supported Features
+---------------------------------
+
+- KVM virtualization is accomplished by using the QEMU program in KVM
+  acceleration mode. KVM acceleration requires that both guest and host have
+  the same fundamental architecture.
+
+- Guest images created under previous QEMU versions are supported by machine
+  version compatibilities built into more recent QEMU versions.
+
+- For ease of use, the QEMU program has defaults which represent traditional
+  usage patterns.
+
+- Guest virtual machine characteristics are specified by a combination of
+  internal defaults, options provided on the QEMU program command-line, runtime
+  configurations set via the monitor interfaces and optional config files. The
+  runtime control of a VM is effected either through the Human Monitor
+  "Protocol" (HMP), or the JSON based programmatical QEMU Monitor Protocol (QMP)
+  interface. For QMP details, see qemu-qmp-ref man page.
+  Since a KVM guest runs in the context of a normal linux process, some types
+  of execution controls are managed with linux tools.
+
+- Various standard vCPU types are available, along with the ability to specify
+  individual CPU features visible to the guest.
+
+- QEMU incorporates a SEABIOS based system BIOS and iPXE based PXE ROMs, which
+  allow boot options common to physical systems, along with other features
+  tailored to virtualization. Various VGABIOS ROMs, also from the SEABIOS
+  project, are also included. A UEFI based guest boot environment is also
+  available by using the firmware provided by the qemu-ovmf-x86_64 package.
+
+- Some QEMU messages have been localized to various languages. This is provided
+  by the optional qemu-lang package. Keyboard mappings for various nationalities
+  is also provided.
+
+- Virtual machine lifecycle controls include startup through the system BIOS or
+  kernel boot, ACPI or legacy based shutdown, execution pausing, the saving and
+  restoring of machine state or disk state, VM migration to another host, and
+  miscellaneous controls available through the "monitors" mentioned above.
+
+- Guest execution state may be "moved" in both time (save/restore) and space
+  (static and live migration). These migrations or save/restore operations can
+  take place either from certain prior SLES versioned hosts to a SLES 15 SP4
+  host or between hosts of the same version. Certain other restrictions also
+  apply.
+
+- Security considerations include seccomp2 based sandboxing, vTPM, privileged
+  helpers and a security model which allows running guests as a non-root user.
+
+- QEMU/KVM supports a wide range of operating systems within the VMs. See the
+  online SUSE documentation for supported OS's. Windows guests can optionally be
+  accelerated with QEMU/KVM provided Hyper-V hypercalls, or with paravirtual
+  drivers from the SUSE Virtual Machine Driver Pack. Linux includes a number of
+  paravirtual drivers as well.
+
+- QEMU provides best effort reuse of existing disk images, including those with
+  systems installed, through geometry probing. Also disk images produced by
+  other popular virtualization technologies may be imported into QEMU supported
+  storage formats. These QEMU formats include features which exploit the
+  benefits of virtualization.
+
+- Memory, cpu and disk space overcommit are possible and can be beneficial when
+  done responsibly. Additional management of these resources comes in the form
+  of memory ballooning or hotplug, host KSM, vcpu hot-add, online disk resizing,
+  trim, discard and hole punching.
+
+- Guest performance is enhanced through the use of virtio devices, various disk
+  caching modes, network acceleration via the vhost-net kernel module, multi-
+  queue network transmit capabilities, host transparent huge pages (THP) and
+  direct hugetlb usage. Physical PCI and USB devices may also be passed through
+  to the guest, including SR-IOV VF's.
+
+- The guest UI is accessable via GTK, VNC, Spice, and serial (including curses
+  TUI) interfaces.
+
+- Guest timekeeping is supported in a variety of ways, including a paravirtual
+  clocksource, and options for the various guest clocks for how to handle the
+  timeslicing of the guest's execution on the host.
+
+- Guest OS's interact with virtualized hardware including a choice of either
+  older or more recent x86 system chipsets, system devices and buses, and a
+  variety of common storage and networking emulated devices. SMBIOS and ACPI
+  table details can be customized.
+
+- In addition to the para-virtualized devices already mentioned, other devices
+  and infrastructure designed to avoid virtualization "problem areas" are
+  available such as SPICE graphics, vmmouse emulation, tablet style pointer
+  interfaces and virtio based UI interfaces.
+
+- A built-in user-mode network (SLIRP) stack is available.
+
+- Portions of the host file system may be shared with a guest by using virtFS.
+
+- A guest "agent" is available for SLES 15 SP4 KVM guests via the
+  qemu-guest-agent package. This allows some introspection and control of the
+  guest OS environment from the host.
+
+QEMU/KVM Technology Previews
+----------------------------
+
+- Nested VMX and SVM virtualization is possible.
+
+- All features indicated as not being supported in this document fall under the
+  Technology Preview definition contained in the main product's release notes.
+
+Noteworthy QEMU/KVM Unsupported Features
+----------------------------------------
+
+- Note that some features are unsupported simply due to lack of validation. If
+  an existing feature is desired, but not marked supported, let SUSE know about
+  your requirements.
+
+- The TCG "acceleration" mode may be helpful for problem isolation, but
+  otherwise presents insufficient benefit and stability.
+
+- Use of -cpu host is not supported in all host/guest configurations.
+
+- GlusterFS integration is not enabled.
+
+Deprecated, Superseded, Modified and Dropped Features
+-----------------------------------------------------
+
+- https://qemu-project.gitlab.io/qemu/about/deprecated.html and
+  https://qemu-project.gitlab.io/qemu/about/removed-features.html
+  These websites track features deprecation and removal at the upstream
+  development level. Our qemu package inherits this community direction, but be
+  aware that we can and will deviate as needed. Those deviations and additional
+  information can be found in this section. Feature deprecation as well as
+  removed features are also tracked in the "System Emulation" section of the
+  documentation installed with the qemu package.
+
+- qemu-img: Deprecate use of -b without -F. Creating an image that requires
+  format probing of the backing image is potentially unsafe and is now
+  deprecated.
+
+- When no video adapter is specified, the default used is stdvga. This differs
+  from the default of prior releases which was cirrus. The cirrus adapter was
+  considered too outdated to continue to use as the default.
+
+- The deprecated windows drivers (win-virtio-drivers.iso) are no longer provided.
+  The Virtual Machine Driver Pack is the supported way to get virtio drivers for
+  Windows guests.
+
+- The use of ",boot=on" for virtio disks is no longer needed since the bios used
+  supports the virtio block interface directly. In fact, its usage may cause
+  problems, and is now considered deprecated.
+
+- The previously non-persistent backing file with pmem=on is deprecated. Modify
+  VM configuration to set pmem=off to continue using fake NVDIMM with backing
+  file or move backing file to NVDIMM storage and keep pmem=on.
+
+- The use of "?" as a parameter to "-cpu", "-soundhw", "-device", "-M",
+  "-machine" and "-d" is now considered deprecated. Use "help"
+  instead.
+
+- The use of "if=scsi" as a parameter to "-drive" does not work anymore with PC
+  machine types, as it created an obsolete SCSI controller model.
+
+- Passthrough of a host floppy device is now considered deprecated.
+
+- Use of aio=native without direct cache mode also being specified (cache=none,
+  cache=directsync, or cache.direct=on) is no longer allowed.
+
+- The use of image encryption in qcow and qcow2 formats is now considered
+  deprecated.
+  Analysis has shown it to be weak encryption, in addition to suffering from
+  poor design. Images can easily be converted to a non-encrypted format.
+
+- Use of acpi, boot-opts, and smp-opts in a -readconfig config file are now
+  considered deprecated. In the future those names will be standardized to
+  acpitable, boot, and smp respectively.
+
+- When only a partial SMP topology is provided (ie only some of sockets, cores,
+  threads) the derived guest ABI is not guaranteed to be equivalent in future
+  versions.
+
+- These previously supported command line options are now considered deprecated:
+  -display sdl,window_close= (use -display sdl,window-close)
+  -no-quit (use -display ...,window-close=off)
+  -M option kernel-irqchip=off
+  -chardev tty (use serial name instead)
+  -chardev paraport (use parallel name instead)
+  -device virtio-blk,scsi= (use virtio-scsi instead)
+  -device virtio-blk-pci,scsi= (use virtio-scsi instead)
+  -enable-fips (not really helpful - see https://git.qemu.org/?p=qemu.git;a=commit;h=166310299a1e7824bbff17e1f016659d18b4a559 for details)
+  -realtime mlock= (use -overcommit mem-lock= instead)
+  -spice password=string (use password-string option instead)
+  -writeconfig (no replacement - never really worked right)
+  -share and noshare must be replaced by share=on/share=off
+  -nodelay must be replaced by nodelay=on rather than delay=off
+  -object-add options opened=on and loaded=on (both had no effect)
+
+- These previously supported command line options are no longer supported:
+  -device ide-drive (use ide-hd or ide-cd instead)
+  -device scsi-disk (use scsi-hd or scsi-cd instead)
+
+- The previously supported machine types pc-0.12, pc-0.14 and pc-0.15 are no
+  longer recognized. Switch to a newer machine type.
+ 
+- These previously supported command line options are no longer recognized:
+  -balloon (use -device virtio-balloon instead)
+  -clock
+  -device ivshmem (use ivshmem-doorbell or ivshmem-plain instead)

+- Specifying a cpu feature with both "+feature/-feature" and "feature=on/off"

+- This previously unsupported QMP commands is no longer recognized:

+
+- Due to the lack of migration support (mainly due to ahci interface issues)
+  and other unstable interface issues, earlier versions of the q35 machine type
+  are not supported in this release. The current q35 machine type is however now
+  fully supported.
+
+- Due to upstream's decision to no longer fully support the qed storage format
+  going forward (since it really provides no benefit over qcow2 and is now no
+  longer actively maintained upstream), creating qed storage images is no longer
+  supported and it is highly discouraged to continue using existing qed images.
+  They should instead be converted to another supported format.
+
+- If KVM Intel nested virtualization is enabled, and the guest is passed the vmx
+  feature, then live migration or save/restore is prohibited.
+
+QEMU Command-Line and Monitor Syntax and Support
+------------------------------------------------
+
+- The QEMU program command-line syntax is as follows:
+  qemu-system-i386 [options] [disk_image]
+  qemu-system-x86_64 [options] [disk_image]
+
+  Where 'options' are taken from the options listed below, and 'disk_image' is
+  the file system reference to the x86 guest's primary IDE based hard disk
+  image. This image as well as those used with -drive or -cdrom, may be in the
+  raw (no format) or qcow2 storage formats, and may be located in files within
+  the host filesystem, logical volumes, host physical disks, or network based
+  storage. Read only media may also be accessed via URL style protocol
+  specifiers.
+
+  Note that as a general rule, as new command line options are added which serve
+  to replace an older option or interface, you are strongly encouraged to adapt
+  your usage to the new option. The new option is being introduced to provide
+  better functionality and usability going forward. In some cases existing
+  problems or even bugs in older interfaces cannot be fixed due to functional
+  expectations, but are resolved in the newer interface or option.
+  This advice includes moving to the most recent machine type (eg pc-i440fx-6.1
+  instead of pc-i440fx-6.0) if possible.
+

+  -accel ...
