SLES 15 SP2 QEMU/KVM RELATED SUPPORT STATEMENTS
|
|
|
|
Overview
|
|
--------
|
|
|
|
The QEMU based packages included with SLES 15 SP2 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) 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 SP2,
|
|
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 SP2
|
|
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 SP2 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 options is now considered deprecated:
|
|
-device scsi-disk (use scsi-hd or scsi-cd)
|
|
|
|
- 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)
|
|
|
|
- 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:
|
|
-bt
|
|
|
|
- These previously unsupported command line options are no longer recognized:
|
|
-device at24c-eeprom
|
|
-device mmio_interface
|
|
-device ssi-sd
|
|
-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
|
|
cpu-add
|
|
migrate_set_downtime
|
|
migrate_set_speed
|
|
|
|
- These previously supported monitor commands are no longer recognized:
|
|
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:
|
|
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
|
|
|
|
- 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-4.2
|
|
instead of virt-3.1) if possible.
|
|
