As Mark pointed out, checking the permissions should be enough, so
"ls -lZ" will do. I don't know if "Local on host" means exactly what I
think, but in case it's not managed using vdsm, that directory may need
to me mounted from somewhere, libvirt itself doesn't do that (unless
it's in network filesystem pool).

In case this goes down to a problem in libvirt, feel free to say what's
wrong and I'll see what I can do about it.
