# 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.

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.

## 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:

- 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.

-accel ...
-action ...
-add-fd ...
-alt-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 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

-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:

block_passwd
change (use blockdev-change-medium or change-vnc-password instead)
cpu-add (use device_add instead)

migrate_set_speed (use migrate-set-parameters instead)
query-cpus (use query-cpus-fast instead)

- 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 ...
-blockdev ...
-boot ...

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)
-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 case of specified sockets, cores, and threads not matching the vcpu count
is no longer silently ignored. QEMU now requires that the topology match the
vcpu count.
- 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:
-no-kvm-pit
-soundhw (use -device ... instead)
- These previously unsupported command line options are no longer recognized:

- The previously unsupported machine types pc-0.10, pc-0.11, pc-0.13,
pc-1.0, pc-1.1, pc-1.2 and pc-1.3 are are no longer recognized.
- These previously supported QMP commands are now deprecated:

- 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)
x-input-send-event (use input-send-event instead)
- This previously unsupported QMP commands is no longer recognized:
x-nbd-server-add-bitmap
- 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.
- The following command line options are supported:
-accel ...
-action ...
-add-fd ...
-alt-grab
-append ...
-audio-help
-audiodev

-blockdev ...
-boot ...
-cdrom ...
