The [libvirt] tag in the prefix is done automatically, you don't have to

Basically it's what's written. "virsh hostname" will give you the
hostname of the hypervisor (host), but "virsh domhostname <domain>" is
trying to get the hostname of the specified domain (guest).

I don't know about anyone trying to work on this, but it doesn't mean it
won't change. It's possible to implement it for some other hypervisors
as well, but nobody had the need to, I guess.
