Control: tags 931243 + fixed-upstream
This issue has been recognized and fixed by the upstream developers at
https://libvirt.org/git/?p=libvirt.git;a=commit;h=1d49cdcd116186e079db5668893da17f56141652
The below is the upstream commit log:
util: vircgroupv2: don't error out if enabling controller
I found a much better workaround.
rtkit works fine after the CGroup V2 CPU controller is enabled.
So, if the V2 CPU controller is enabled before a user process gets
the realtime priority, libvirt-daemon works also fine.
I made the following lines to
Package: libvirt0
Version: 5.2.0-2
Followup-For: Bug #931243
Control: found 931243 5.2.0-2
Dear Maintainer,
I installed version 5.2.0-2 from the experimental and
confirmed that this issue still exists in 5.2.0-2.

Dear Maintainer,
* libvirt0 tries to add "cpu" controller under the cgroup v2
(a.k.a. unified cgroup hierarchy), which can be enabled by
"systemd.unified_cgroup_hierarchy=1" boot option in /etc/default/grub
