Hi,

I've tried to run a Parabola installation inside libvirt LXC (inside a
guix system intallation) and it gives me the following error:
> Unable to complete install: 'internal error: guest failed to start: Failure in libvirt_lxc startup: Unable to create directory /sys/fs/cgroup/unified: No such file or directory
> '
> 
> Traceback (most recent call last):

Is it already fixed in libvirt master branch? Or is it a new bug?

Also is there any existing workarounds?

Denis.
