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!
