[PATCH 0/2] qemu: Don't crash on empty USB cdrom hotplug
by Peter Krempa
Fix the main crash cause and also forbid empty USB devices as qemu
doesn't accept them.
Peter Krempa (2):
qemu: block: Allow NULL 'data' in 'qemuBlockStorageSourceChainDetach'
qemu: validate: Reject empty USB disks

[PATCH] qemu: Add support for RAPL MSRs feature
by Anthony Harivel
Add the support in libvirt to activate the RAPL feature in QEMU.
This feature is activated with -accel kvm,rapl=true,path=/path/sock.sock
in QEMU.
The feature is activated in libvirt with the following XML
configuration:
<kvm>
[...]
<rapl state ='on' socket='/run/qemu-vmsr-helper.sock'/>
[...]
</kvm>
See: https://gitlab.com/qemu-project/qemu/-/commit/0418f90809aea5b375c859e744c...

[PATCH] security: apparmor: Allow QEMU read /proc/sys/vm/max_map_count
by Michal Privoznik
In its commit v9.0.0-rc0~1^2 QEMU started to read
/proc/sys/vm/max_map_count file to set up coroutine limits better
(something about VMAs, mmap(), see the commit for more info).
Allow the file in apparmor profile.

New features tests fails
by Anthony Harivel
Hi,
I'm trying to implement the libvirt part of a new feature that has
landed in QEMU staging [1].
The current draft of this implementations is the following [2].
It compiles on top of master.
But when I want to run the tests suites, I hit an issue I don't managed
to find the problem.
It runs until:
[...]
278/279 libvirt:bin / qemuxmlconftest FAIL 8.63s exit status 1
[...]
then it tells me to run the following to understand the issue:
VIR_TEST_DEBUG=1 VIR_TEST_RANGE=850-851,854-855 /home/aharivel/work/libvirt/build/tests/qemuxmlconftest
It outputs this:
[...]
850) QEMU XML def -> XML kvm-features.x86_64-latest ...
In '/home/aharivel/work/libvirt/tests/qemuxmlconfdata/kvm-features.x86_64-latest.xml':

Offset 527
Expect [/]
Actual [ socket='(null)'/]
[...] ... FAILED
I certainly did something wrong in the implementation but I don't figure
it out. I understand the Expect / Actual tests.
I'm guessing the issue is that it needs to run the QEMU version where the
feature is possible but I don't see how can tell the test to run this
particular version.
Any advise would be greatly appreciate.
Thanks
Regards,
Anthony

[PATCH 0/3] Fix ARP table parsing over netlink messages
by Martin Kletzander
Somehow it happened that some kernels (I noticed this with 6.10.0 and 6.10.2 on
various machines) started sending NLMSG_DONE message (as they probably should've
even before), but our check for it could've never worked and now `virsh
domifaddr --source arp` sometimes fails with "wrong nlmsg len". So I set out on
a quest to tame the netlink beast and though fierceful debugging and... Oh, I
forgot, nobody reads cover letters. Never mind.
Martin Kletzander (3):
virarptable: Properly calculate rtattr length
virarptable: Fix check for message length
virarptable: End parsing earlier in case of NLMSG_DONE

[PATCH 0/3] Implement support for QCOW2 data files
by Nikolai Barybin
There are use cases when the existing disks (i.e. LVM) are wanted
to be used with advanced features. For this purpose QEMU allows
data-file feature for qcow2 files: metadata is kept in the qcow2
file like usual, but guest data is written to an external file.
These patches enable support for this feature in libvirt.
Nikolai Barybin (3):
conf: add data-file feature and related fields to virStorageSource
storage: add qcow2 filename parsing from header
qemu: enable qcow2 data-file attach to VM on start

Shared LVM and starting/stopping volumes
by dajester2005＠gmail.com
Ran into a situation using a shared LVM2 volume group, where if there were volumes locked by a server, the pool could not be started on another server due to "vgchange -aly" not being able to acquire locks on all volumes in the pool. This was referenced in issue #38 on gitlab.
Long story short, I've experimented with adding APIs for starting/stopping individual volumes in a storage pool, and implementing that API in the logical backend driver. I'm not a C developer by trade, but all the existing tests pass. I'd like to submit this for some feedback, and see what would be needed to incorporate this, or similar API: https://gitlab.com/dajester2013/libvirt/-/tree/shared-lvm-storage-mods
