[libvirt PATCH] lxc: remove no longer working netns check
by Leigh Brown
Since iproute2 v6.12.0, the command "ip link set lo netns -1" can
no longer be used to check for netns support, as it now validates
PIDs are not less than zero.
Since every kernel we care about has the support, just remove the
check.

[PATCH v3 0/5] ch: handle events from cloud-hypervisor
by Purna Pavan Chandra Aekkaladevi
changes from v2->v3:
* Remove patch 'utils: Implement virFileIsNamedPipe' as it is no more needed.
* Remove the eventmonitorpath only if it exists
* Added domain name as a prefix to logs from ch_events.c. This will make
debugging easier.
* Simplified event parsing logic by reserving a byte for null char.
changes from v1->v2:
* Rebase on latest master
* Use /* */ for comments
* Remove fifo file if already exists
* Address other comments from Praveen Paladugu
cloud-hypervisor raises various events, including VM lifecylce operations
such as boot, shutdown, pause, resume, etc. Libvirt will now read these
events and take the necessary actions, such as correctly updating the
domain state. A FIFO file is passed to `--event-monitor` option of
cloud-hypervisor. Libvirt creates a new thread that acts as the reader
of the fifo file and continuously monitors for new events. Currently,
shutdown events are handled by updating the domain state appropriately.

[libvirt PATCH] qemu: tpm: do not update profile name for transient domains
by Ján Tomko
If we do not have a persistent definition, there's no point in
looking for it since we cannot store it.
This fixes the crash when starting a transient domain.

Release of libvirt-10.10.0
by Jiri Denemark
The 10.10.0 release of both libvirt and libvirt-python is tagged and
signed tarballs are available at
https://download.libvirt.org/
https://download.libvirt.org/python/
Thanks everybody who helped with this release by sending patches,
reviewing, testing, or providing feedback. Your work is greatly
appreciated.
* New features
* qemu: add multi boot device support on s390x
For classical mainframe guests (i.e. LPAR or z/VM installations), you
always have to explicitly specify the disk where you want to boot from (or
"IPL" from, in s390x-speak -- IPL means "Initial Program Load").
In the past QEMU only used the first device in the boot order to IPL from.
With the new multi boot device support on s390x that is available with QEMU
version 9.2 and newer, this limitation is lifted. If the IPL fails for the
first device with the lowest boot index, the device with the second lowest
boot index will be tried and so on until IPL is successful or there are no
remaining boot devices to try.
Limitation: The s390x BIOS will try to IPL up to 8 total devices, any
number of which may be disks or network devices.
* qemu: Add support for versioned CPU models
Updates to QEMU CPU models with -vN suffix can now be used in libvirt just
like any other CPU model.
* qemu: Support for the 'data-file' QCOW2 image feature
The QEMU hypervisor driver now supports QCOW2 images with 'data-file'
feature present (both when probing form the image itself and when specified
explicitly via ``<dataStore>`` element). This can be useful when it's
required to keep data "raw" on disk, but the use case requires features
of the QCOW2 format such as incremental backups.
* swtpm: Add support for profiles
Upcoming swtpm release will have TPM profile support that allows to
restrict a TPM's provided set of crypto algorithms and commands. Users can
now select profile by using ``<profile/>`` in their TPM XML definition.
* Improvements
* qemu: Support UEFI NVRAM images on block storage
Libvirt now allows users to use block storage as backend for UEFI NVRAM
images and allows them to be in format different than the template. When
qcow2 is used as the format, the images are now also auto-populated from the
template.
* qemu: Automatically add IOMMU when needed
When domain of 'qemu' or 'kvm' type has more than 255 vCPUs IOMMU with EIM
mode is required. Starting with this release libvirt automatically adds one
(or turns on the EIM mode if there's IOMMU without it).
* ch: allow hostdevs in domain definition
The Cloud Hypervisor driver (ch) now supports ``<hostdev/>``-s.
* ch: Enable callbacks for ch domain events
The Cloud Hypervisor driver (ch) now supports emitting events on domain
define, undefine, start, boot, stop and destroy.
* Bug fixes
* qemu: Fix reversion and inactive deletion of internal snapshots with UEFI NVRAM
In `v10.9.0 (2024-11-01)`_ creation of internal snapshots of VMs with UEFI
firmware was allowed, but certain operations such as reversion or inactive
deletion didn't work properly as they didn't consider the NVRAM qcow2 file.
* virnetdevopenvswitch: Warn on unsupported QoS settings
For OpenVSwitch vNICs libivrt does not set QoS directly using 'tc' but
offloads setting to OVS. But OVS is not as feature full as libvirt in this
regard and setting different 'peak' than 'average' results in vNIC always
sticking with 'peak'. Produce a warning if that's the case.
Enjoy.
