qemu/supported.s390.txt
Bruce Rogers fc6feafd4e Accepting request 854151 from home:bfrogers:branches:Virtualization 
- Update to v5.2.0: See http://wiki.qemu.org/ChangeLog/5.2
  Take note that ongoing feature deprecation is tracked at both
  http://wiki.qemu-project.org/Features/LegacyRemoval and in
  the deprecated.html file installed with the qemu package
  Some noteworthy changes:
* Dropped system emulators: qemu-system-lm32, qemu-system-unicore32
* Dropped linux user emulator: qemu-ppc64abi32
* Added linux user emulator: qemu-extensaeb
* Unicore32 and lm32 guest support dropped
* New sub-packages (most due to ongoing modularization of QEMU):
  qemu-audio-spice, qemu-hw-chardev-spice, qemu-hw-display-virtio-vga, 
  qemu-hw-display-virtio-gpu, qemu-hw-display-virtio-gpu-pci,
  qemu-ui-spice-core, qemu-ui-opengl, qemu-ivshmem-tools
* x86: A new KVM feature which improves the handling of asynchronous page
  faults is available with -cpu ...,kvm-async-pf-int (requires Linux 5.8)
* s390: More instructions emulated under TCG
* PowerPC: nvdimm= machine option now functions correctly; misc improvements
* ARM: new boards: mps2-an386 (Cortex-M4 based) and mps2-an500
  (Cortex-M7 based),  raspi3ap (the Pi 3 model A+), raspi0 (the Pi Zero)
  and raspi1ap (the Pi A+)
* RISC-V: OpenSBI v0.8 included by default; Generic OpenSBI platform used
  when no -bios argument is supplied; Support for NUMA sockets on Virt
  and Spike Machines; Support for migrating machines; misc improvements
* Misc NVMe improvements
* The 'vhost-user-blk' export type has been added, allowing
  qemu-storage-daemon to act as a vhost-user-blk device backend
* The SMBIOS OEM strings can now come from a file
* 9pfs - misc performance related improvements
* virtiofs - misc improvements
* migration: The default migration bandwidth has been increased to 1Gbps
  (users are still encouraged to tune it to their own hardware); The new
  'calc-dirty-rate' and 'query-dirty-rate' QMP commands can help determine
  the likelihood of precopy migration success; TLS+multifd now supported
  for higher bandwidth encrypted migration; misc minor features added
* Misc minor block features added
* Misc doc improvements
* qemu-microvm subpackage change: the bios-microvm.bin is now SeaBIOS based,
  and the qboot based on is now qboot.rom
* elf2dmp is no longer part of qemu-tools (it was never intended to be
  a packaged binary)
* Some subpackages which were 'Requires' are now 'Recommends', allowing for
  a smaller qemu packaging footprint if needed
* Patches dropped (included in release tarball, unless otherwise noted):

  roms-Makefile-add-cross-file-to-qboot-me.patch
  qboot-add-cross.ini-file-to-handle-aarch.patch
  usb-Help-compiler-out-to-avoid-a-warning.patch
- In spec file, where reasonable, switch BuildRequires: XXX-devel
  to be pkgconfig(XXX') instead
- No longer disable link time optimization for qemu for x86. It looks like
  either the build service, qemu code changes and/or the switch to meson
  have resolved issues previously seen there. We still see problems for
  other architectures however.
- For the record, the following issues reported for SUSE SLE15-SP2
  are either fixed in this current package, or are otherwise no longer
  an issue: bsc#1172384 bsc#1174386 bsc#1174641 bsc#1174863 bsc#1175370
  bsc#1175441 bsc#1176494 CVE-2020-13361 CVE-2020-14364 CVE-2020-15863
  CVE-2020-16092 CVE-2020-24352
  and the following feature requests are satisfied by this package:
  jsc#SLE-13689 jsc#SEL-13780 jsc#SLE-13840
- To be more accurate, and to align with other qemu packaging
  practices, rename the qemu-s390 package to qemu-s390x. The old
  name (in the rpm namespace) is provided with a "Provides"
  directive, and an "Obsoletes" done against that name for prior
  qemu versions, as is standard practice (boo#1177764 jsc#SLE-17060)
- Take this opportunity to remove some ancient Split-Provides
  mechanisms which can't conceivably be needed any more:
  qemu-block-curl provided: qemu:%_libdir/%name/block-curl.so
  qemu-guest-agent provided: qemu:%_bindir/qemu-ga
  qemu-tools provided: qemu:%_libexecdir/qemu-bridge-helper
- Disable linux-user 'ls' test on 32 bit arm. It's failing with
  "Allocating guest commpage: Cannot allocate memory" error, which
  we should hunt down, but for now we don't want it to prevent the
  package from being built

SLES 15 SP3 QEMU/KVM RELATED SUPPORT STATEMENTS
Overview
--------
The QEMU based packages included with SLES 15 SP3 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 SP3
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 SP3 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
-----------------------------------------------------
- http://wiki.qemu-project.org/Features/LegacyRemoval
This website tracks feature 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 is also tracked
in Appendix B of the qemu-doc.* files installed with the qemu package.
- 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.
- This previously supported command line option is now considered deprecated:
-device virtio-blk,scsi= (use virtio-scsi instead)
-device virtio-blk-pci,scsi= (use virtio-scsi instead)
-realtime mlock= (use -overcommit mem-lock= instead)
- 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)
-sdl
-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
-device ide-drive (use ide-hd or ide-cd)
-device scsi-disk (use scsi-hd or scsi-cd)
-soundhw (use -device ... instead)
-tb-size
- These previously unsupported command line options are no longer recognized:
-device mmio_interface
-device ramfb
-device vhost-user-vsock-pci-transitional
-device vhost-vsock-pci-transitional
-device virtio-iommu-pci-transitional
-enable-hax
-tdf
-xen-create
- These previously supported QMP commands are now deprecated:
change (use blockdev-change-medium or change-vnc-password instead)
cpu-add
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
migrate_set_downtime
migrate_set_speed
- These previously supported monitor commands are no longer recognized:
cpu-add
pci_add (use device_add instead)
pci_del (use device_del instead)
- These previously unsupported monitor command are now deprecated:
acl_add ...
acl_policy ...
acl_remove ...
acl_reset ...
acl_show ...
- These previously unsupported monitor commands are no longer recognized:
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-5.2 instead of s390-ccw-virtio-4.2) if possible.
- The following command line options are supported:
-accel ...
-add-fd ...
-alt-grab
-append ...
-audio-help
-audiodev
-bios ...
-blockdev ...
-boot ...
-cdrom ...
-chardev ..
