SLES 12 SP3 QEMU/KVM RELATED SUPPORT STATEMENTS
|
||
|
|
|
||
|
|
Overview
|
||
|
|
--------
|
||
|
|
|
||
|
|
The QEMU based packages included with SLES 12 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)
|
||
|
|
is offered at the L3 (full support) level. KVM on the IBM System z (s390x)
|
||
|
|
is in technology preview, and KVM for the ARM64 architecture (AArch64) is L3
|
||
|
|
supported for certain partner-specific use cases. 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 provided 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), qemu-system-s390x (System z host), and
|
||
|
|
qemu-system-aarch64 (ARM64 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) 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 /usr/share/doc/packages/qemu/qmp-commands.txt.
|
||
|
|
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
|
||
|
|
now possible 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 12 SP3
|
||
|
|
or between hosts of the same version. Certain other restrictions also apply.
|
||
|
|
|
||
|
|
- Security considerations include secccomp2 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, SDL, 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 12 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
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
- KVM on System z using the qemu-system-s390x system emulator is not yet fully
|
||
|
|
supported. KVM on ARM64 (AArch64) usage outside of the supported partner
|
||
|
|
specific use cases is being evaluated and not yet L3 supported.
|
||
|
|
|
||
|
|
- Specifying and placing PCI devices on a PCI bridge allows for a greater number
|
||
|
|
of devices.
|
||
|
|
|
||
|
|
- 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
|
||
|
|
-----------------------------------------------------
|
||
|
|
|
||
|
|
- 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 use of "?" as a parameter to "-cpu", "-soundhw", "-device", "-M",
|
||
|
|
"-machine", "-d", and "-clock" 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:
|
||
|
|
-device ivshmem (use ivshmem-doorbell or ivshmem-plain instead)
|
||
|
|
|
||
|
|
- These previously supported command line options are no longer supported:
|
||
|
|
-device pci-assign, -device kvm-pci-assign (use -device vfio-pci instead)
|
||
|
|
|
||
|
|
- These previously supported command line options are no longer recognized:
|
||
|
|
-device pc-sysfw (no longer needed)
|
||
|
|
|
||
|
|
- Specifying a CPUID 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:
|
||
|
|
-no-kvm-irqchip (use -machine kernel_irqchip=off instead)
|
||
|
|
-no-kvm-pit
|
||
|
|
-no-kvm-pit-reinjection
|
||
|
|
-tdf
|
||
|
|
|
||
|
|
- 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.
|
||
|
|
|
||
|
|
- These previously unsupported command line options are no longer recognized:
|
||
|
|
-device ccid-card-passthru
|
||
|
|
-device cfi.pflash01
|
||
|
|
-device esp
|
||
|
|
-device exynos4210-ehci-usb
|
||
|
|
-device fusbh200-ehci-usb
|
||
|
|
-device icc-bridge
|

|
|
-device q35-pcihost
|

|
||
|
|
-device sysbus-ohci
|
||
|
|
-device tegra2-ehci-usb
|
||
|
|
-device testdev (use -device pc-testdev instead)
|
||
|
|
-device virtio-mmio
|
||
|
|
-device xln,ps7-usb
|
||
|
|
-enable-nesting
|
||
|
|
-kvm-shadow-memory (use -machine kvm_shadow_mem= instead)
|
||
|
|
-M mac
|
||
|
|
-nvram
|
||
|
|
-old-param
|
||
|
|
-osk
|
||
|
|
-pcidevice (use -device vfio-pci instead)
|
||
|
|
-qtest
|
||
|
|
-semihosting
|
||
|
|
|
||
|
|
- These previously supported monitor commands are no longer recognized:
|
||
|
|
cpu_set
|
||
|
|
pci_add (use device_add instead)
|
||
|
|
pci_del (use device_del instead)
|
||
|
|
|
||
|
|
- This previously unsupported QMP command is now supported under a new name:
|
||
|
|
x-input-send-event (use input-send-event instead)
|
||
|
|
|
||
|
|
- 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.
|
||
|
|
|
||
|
|
QEMU Command-Line and Monitor Syntax and Support
|
||
|
|
------------------------------------------------
|
||
|
|
|
||
|
|
- The QEMU program command-line syntax is as follows:
|
||
|
|
qemu-system-aarch64 [options]
|
||
|
|
qemu-system-i386 [options] [disk_image]
|
||
|
|
qemu-system-s390x [options]
|
||
|
|
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 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), qcow2 or qed 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-2.8
|
||
|
|
instead of pc-i440fx-2.6) if possible.
|
||
|
|
|
||
|
|
- The following command line options are supported:
|
||
|
|
-add-fd ...
