[libvirt] Problem with version 5.5.x

[Raghav Gururajan]

Hello Folks!

The distro I use (Guix System) has updated it's libvirt version from
5.4.x to 5.5.x, few days ago.

After the update, there is this following error:
"libvirt.libvirtError: Unable to read from
'/sys/fs/cgroup/unified/machine/cgroup.controllers': No such file or
directory".

It appears that libvirt is searching
"/sys/fs/cgroup/unified/machine/cgroup.controllers" path, instead of
"/sys/fs/cgroup/unified/cgroup.controllers" path; as the directory
"machine" does not actually exist.

The libvirt was working just fine before the update. So it seems like a
critical bug with version 5.5.x that needs to be patched ASAP.

Thank you!

Regards,
RG.
