10.7.0
* **Security**
* CVE-2024-8235: Crash of ``virtinterfaced`` via ``virConnectListInterfaces()``
A refactor of the code fetching the list of interfaces for multiple APIs
introduced corner case on platforms where allocating 0 bytes of memory
results in a NULL pointer.
This corner case would lead to a NULL-pointer dereference and subsequent
crash of ``virtinterfaced`` if ``virConnectListInterfaces()`` is called
requesting 0 networks to be filled.
The bug was introduced in libvirt-10.4.0
* **New features**
* qemu: Introduce the ability to disable the built-in PS/2 controller
It is now possible to control the state of the ``ps2`` feature in the
domain XML for descendants of the generic PC machine type (``i440fx``,
``q35``, ``xenfv`` and ``isapc``).
* **Improvements**
* ch: support restore with network devices
Cloud-Hypervisor starting from V40.0 supports restoring file descriptor
backed network devices. So, create new net fds and pass them via
SCM_RIGHTS to CH during restore operation.
* ch: support basic networking modes
Cloud-Hypervisor driver now supports Ethernet, Network (NAT) and Bridge
networking modes.
10.6.0
* **Removed features**
* qemu: Require QEMU-5.2.0 or newer
The minimal required version of QEMU was bumped to 5.2.0.
* **New features**
* qemu: Add support for the 'pauth' Arm CPU feature
* Introduce pstore device
The aim of pstore device is to provide a bit of NVRAM storage for guest
kernel to record oops/panic logs just before it crashes. Typical usage
includes usage in combination with a watchdog so that the logs can be
inspected after the watchdog rebooted the machine.
* **Improvements**
* qemu: Set 'passt' net backend if 'default' is unsupported
If QEMU is compiled without SLIRP support, and if domain XML allows it,
starting from this release libvirt will use passt as the default backend
instead. Also, supported backends are now reported in the domain
capabilities XML.
* qemu: add a monitor to /proc/$pid when killing times out
In cases when a QEMU process takes longer to be killed, libvirt might have
skipped cleaning up after it. But now a /proc/$pid watch is installed so
this does not happen ever again.
* **Bug fixes**
* virt-aa-helper: Allow RO access to /usr/share/edk2-ovmf
When binary version of edk2 is distributed, the files reside under
/usr/share/edk2-ovmf. Allow virt-aa-helper to generate paths under that
directory.
* virt-host-validate: Allow longer list of CPU flags
During its run, virt-host-validate parses /proc/cpuinfo to learn about CPU
flags. But due to a bug it parsed only the first 1024 bytes worth of CPU
flags leading to unexpected results. The file is now parsed properly.
* capabilities: Be more forgiving when decoding OEM strings
On some systems, OEM strings are scattered in multiple sections. This
confused libvirt when generating capabilities XML. Not anymore.
10.5.0
* **New features**
* Introduce SEV-SNP support
SEV-SNP is introduced as another type of ``<launchSecurity/>``. Its support
is reported in both domain capabilities and ``virt-host-validate``.
* **Improvements**
* tools: virt-pki-validate has been rewritten in C
The ``virt-pki-validate`` shell script has been rewritten as a C program,
providing an output format that matches ``virt-host-validate``, removing
the dependency on ``certtool`` and providing more comprehensive checks
of the certificate properties.
* qemu: implement iommu coldplug/unplug
The ``<iommu/>`` device can be now cold plugged and/or cold unplugged.
* Pass shutoff reason to release hook
Sometimes in release hook it is useful to know if the VM shutdown was
graceful or not. This is especially useful to do cleanup based on the VM
shutdown failure reason in release hook. Starting with this release the
last argument 'extra' is used to pass VM shutoff reason in the call to
release hook.
* nodedev: improve DASD detection
In newer DASD driver versions the ID_TYPE tag is supported. This tag is
missing after a system reboot but when the ccw device is set offline and
online the tag is included. To fix this version independently we need to
check if a device detected as type disk is actually a DASD to maintain the
node object consistency and not end up with multiple node objects for
DASDs.
* **Bug fixes**
* remote_daemon_dispatch: Unref sasl session when closing client connection
A memory leak was identified when a client started SASL but then suddenly
closed connection. This is now fixed.
* qemu: Fix migration with disabled vmx-* CPU features
Migrating a domain with some vmx-* CPU features marked as disabled could
have failed as the destination would incorrectly expect those features to
be enabled after starting QEMU.
* qemu: Fix ``libvirtd``/``virtqemud`` crash when VM shuts down during migration
The libvirt daemon could crash when a VM was shut down while being migrated
to another host.
10.4.0
* **New features**
* qemu: Support for ras feature for virt machine type
It is now possible to set on/off ``ras`` feature in the domain XML for virt
(Arm) machine type as ``<ras state='on'/>``.
* SSH proxy for VM
Libvirt now installs a binary helper that allows connecting to QEMU domains
via SSH using the following scheme: ``ssh user@qemu/virtualMachine``.
* qemu: Support for ``virtio`` sound model
Sound devices can now be configured to use the virtio model with
``<sound model='virtio'/>``. This model is available from QEMU 8.2.0
onwards.
* network: use nftables to setup virtual network firewall rules
The network driver can now use nftables rules for the virtual
network firewalls, rather than iptables. With the standard build
options, nftables is preferred over iptables (with fallback to
iptables if nftables isn't installed), but this can be modified at
build time, or at runtime via the firewall_backend setting in
network.conf. (NB: the nwfilter driver still uses
ebtables/iptables).
* **Improvements**
* qemu: add zstd to supported compression formats
Extend the list of supported formats of QEMU save image by adding zstd
compression.
* qemu: Implement support for hotplugging evdev input devices
As of this release, hotplug and hotunplug of evdev ``<input/>`` devices is
supported.
* **Bug fixes**
* virsh/virt-admin: Fix ``--help`` option for all commands
A bug introduced in `v10.3.0 (2024-05-02)`_ caused that the attempt to print
help for any command by using the ``--help`` option in ``virsh`` and
``virt-admin`` would print::
$ virsh list --help
error: command 'list' doesn't support option --help
instead of the help output. A workaround for the affected version is to use
the help command::
$ virsh help list
* qemu: Fix ``virsh save`` and migration when storage in question is root_squashed NFS
Attempting to save a VM to a root_squash NFS mount or migrating with disks
hosted on such mount could, in some scenarios, result in error stating::
'Unknown error 255'
The bug was introduced in `v10.1.0 (2024-03-01)`_.
* qemu: Don't set affinity for isolcpus unless explicitly requested
When starting a domain, by default libvirt sets affinity of QEMU process to
all online CPUs. This also included isolated CPUs (``isolcpus=``) which is
wrong. As of this release, isolated CPUs are left untouched, unless
explicitly configured in domain XML.
* qemu_hotplug: Properly assign USB address to hotplugged usb-net device
Previously, the network device hotplug logic would try to ensure only CCW
or PCI addresses. With recent support for the usb-net model, USB addresses
for usb-net network devices are assigned automatically.
* qemu: Fix hotplug of ``virtiofs`` filesystem device with ``<boot order=`` set
The bug was introduced in `v10.3.0 (2024-05-02)`_ when attempting to reject
unsupported configurations. During hotplug the addresses are
assigned after validation and thus errorneously reject valid configs.
10.3.0
* **New features**
* qemu: Proper support for USB network device
USB address is now automatically assigned to USB network devices thus they
can be used without manual configuration.
* conf: Introduce memReserve attribute to <controller/>
Some PCI devices have large non-prefetchable memory. This can be a problem
in case when such device needs to be hotplugged as the firmware can't
foresee such situation. The user thus can override the value calculated at
start to accomodate for such devices.
* **Improvements**
* Improve validation of USB devices
Certain USB device types ('sound', 'fs', 'chr', 'ccid' and 'net') were not
properly handled in the check whether the VM config supports USB and thus
would result in poor error messages.
* virsh: Fix behaviour of ``--name`` and ``--parent`` used together when listing checkpoint and snapshots
The ``checkpoint-list`` and ``snapshot-list`` commands would ignore the
``--name`` option to print only the name when used with ``--parent``.
* Extend libvirt-guests to shutdown only persistent VMs
Users can now choose to shutdown only persistent VMs when the host is being
shut down.
* **Bug fixes**
* qemu: Fix migration with custom XML
Libvirt 10.2.0 would sometimes complain about incompatible CPU definition
when trying to migrate or save a domain and passing a custom XML even
though such XML was properly generated as migratable. Hitting this bug
depends on the guest CPU definition and the host on which a particular
domain was running.
* qemu: Fix TLS hostname verification failure in certain non-shared storage migration scenarios
In certain scenarios (parallel migration, newly also post-copy migration)
libvirt would wrongly pass an empty hostname to QEMU to be used for TLS
certificate hostname validation, which would result into failure of the
non-shared storage migration step::
error: internal error: unable to execute QEMU command 'blockdev-add': Certificate does not match the hostname
* Create OVS ports as transient
Libvirt now creates OVS ports as transient which prevents them from
reappearing or going stale on sudden reboots.
* Clear OVS QoS settings when domain shuts down
Libvirt now clears QoS settings on domain shutdown, so they no longer pile
up in OVS database.
10.2.0
* **New features**
* ch: Basic save and restore support for ch driver
The ch driver now supports basic save and restore operations. This is
functional on domains without any network, host device config defined.
The ``path`` parameter for save and restore should be a directory.
* qemu: Support for driver type ``mtp`` in ``<filesystem/>`` devices
The ``mtp`` driver type exposes the ``usb-mtp`` device in QEMU. The
guest can access files on this driver through the Media Transfer
Protocol (MTP).
* qemu: Added support for the loongarch64 architecture
It is now possible for libvirt to run loongarch64 guests, including on
other architectures via TCG. For the best results, it is recommended to
use the upcoming QEMU 9.0.0 release together with the development version
of edk2.
* qemu: Introduce virDomainGraphicsReload API
Reloading the graphics display is now supported for QEMU guests using
VNC. This is useful to make QEMU reload the TLS certificates without
restarting the guest. Available via the ``virDomainGraphicsReload`` API
and the ``domdisplay-reload`` virsh command.
* **Bug fixes**
* qemu: Fix migration from libvirt older than 9.10.0 when vmx is enabled
A domain with vmx feature enabled (which may be even done automatically
with ``mode='host-model'``) started by libvirt 9.9.0 or older cannot be
migrated to libvirt 9.10.0, 10.0.0, and 10.1.0 as the target host would
complain about a lot of extra ``vmx-*`` features. Migration of similar
domains started by the affected releases to libvirt 9.9.0 and older
does not work either. Since libvirt 10.2.0 migration works again with
libvirt 9.9.0 and older in both directions. Migration from the affected
releases to 10.2.0 works as well, but the other direction remains broken
unless the fix is backported.
* node_device: Don't report spurious errors from PCI VPD parsing
In last release the PCI Vital Product Data parser was enhanced to report
errors but that effort failed as some kernels have the file but don't allow
reading it causing logs to be spammed with::
libvirtd[21055]: operation failed: failed to read the PCI VPD data
Since the data is used only in the node device XML and errors are ignored if
the parsing failed, this release removes all the error reporting.
* qemu: set correct SELinux label for unprivileged virtiofsd
It is now possible to use virtiofsd-based ``<filesystem>`` shares even
if the guest is confined using SELinux.
* qemu: fix a crash on unprivileged virtiofsd hotplug
Hotplugging virtiofsd-based filesystems works now.
* virt-admin: Fix segfault when libvirtd dies
``virt-admin`` no longer crashes when ``libvirtd`` unexpectedly closes
the connection.
10.1.0
* **Security**
* ``CVE-2024-1441``: Fix off-by-one error leading to a crash
In **libvirt-1.0.0** there were couple of interface listing APIs
introduced which had an off-by-one error. That error could lead to a
very rare crash if an array was passed to those functions which did
not fit all the interfaces.
In **libvirt-5.10** a check for non-NULL arrays has been adjusted to
allow for NULL arrays with size 0 instead of rejecting all NULL
arrays. However that made the above issue significantly worse since
that off-by-one error now did not write beyond an array, but
dereferenced said NULL pointer making the crash certain in a
specific scenario in which a NULL array of size 0 was passed to the
aforementioned functions.
* **New features**
* nodedev: Support updating mdevs
The node device driver has been extended to allow updating mediated node
devices. Options are available to target the update against the persistent,
active or both configurations of a mediated device.
**Note:** The support is only available with at least mdevctl v1.3.0 installed.
* qemu: Add support for /dev/userfaultfd
On hosts with new enough kernel which supports /dev/userfaultfd libvirt will
now automatically grant QEMU access to this device. It's no longer needed to
set vm.unprivileged_userfaultfd sysctl.
* qemu: Support clusters in CPU topology
It is now possible to configure the guest CPU topology to use clusters.
Additionally, if CPU clusters are present in the host topology, they will
be reported as part of the capabilities XML.
* network: Make virtual domains resolvable from the host
When starting a virtual network with a new ``register='yes'`` attribute
in the ``<domain>`` element, libvirt will configure ``systemd-resolved``
to resolve names of the connected guests using the name server started
for this network.
* qemu: Introduce dynamicMemslots attribute for virtio-mem
QEMU now allows setting ``.dynamic-memslots`` attribute for virtio-mem-pci
devices. When turned on, it allows memory exposed to guest to be split into
multiple memory slots and thus smaller memory footprint (see the original
commit for detailed explanation).
* **Improvements**
* nodedev: Add ability to update persistent mediated devices by defining them
Existing persistent mediated devices can now also be updated by
``virNodeDeviceDefineXML()`` as long as parent and UUID remain unchanged.
* ch: Enable ``ethernet`` interface mode support
``<interface type='ethernet'/>`` can now be used for CH domains.
* viraccessdriverpolkit: Add missing vtpm case
Secrets with ``<usage type='vtpm'>`` were left unable to be checked for in
the access driver, i.e. in ACL rules. Missing code was provided.
* virt-admin: Notify users to use explicit URI if connection fails
``virt-admin`` doesn't try to guess the URI of the daemon to manage so a
failure to connect may be confusing for users if modular daemons are used.
Add a hint to use the URI of the dameon to manage.
* **Bug fixes**
* qemu_process: Skip over non-virtio non-TAP NIC models when refreshing rx-filter
If ``trustGuestRxFilters`` is enabled for a vNIC that doesn't support it,
libvirt may throw an error when such domain is being started, loaded from a
saved state, migrated, etc. These errors are now silenced, but make sure to
fix such configurations (after previous release it is even possible to
change ``trustGuestRxFilters`` value on live domains via
``virDomainUpdateDeviceFlags()`` or ``virsh device-update``).
* domain: Fix check for overlapping ``<memory/>`` devices
A bug was identified which caused libvirt to report two NVDIMMs as
overlapping even though they weren't. This now fixed.
* vmx: Accept empty fileName for cdrom-image
Turns out, ``fileName`` attribute (which contains path to CDROM image) can
be set to an empty string (``""``) to denote a state in which the CDROM has
no medium in it. Libvirt used to reject such configuration file, but not
anymore.
* qemu_hotplug: Don't lose 'created' flag in qemuDomainChangeNet()
When starting a domain, libvirt tracks what resources it created for it and
which were pre-existing and uses this information to preserve pre-existing
resources when cleaning up after said domain is shut off. But for macvtaps
this information was lost after the macvtap device was changed (e.g. via
``virsh update-device``).
* Fix virStream hole handling
When a client sent multiple holes into a virStream it may have caused
daemon hangup as the daemon stopped processing RPC from the client
temporarily. This is now fixed.
* nodedev: Don't generate broken XML with certain hardware
A broken node device XML would be generated in a rare case when a hardware
device had certain characters in the VPD fields.
* qemu: Fix reservation of manually specified port for disk migration
A manually specified port would not be relased after disk migration making
it impossible to use it again.
