Maybe the problem is that OpenVZ and Virtuozzo are not identical. See
this thread on the user list about the difference between ctid and
vpsid:

https://www.redhat.com/archives/libvirt-users/2011-May/msg00070.html
https://www.redhat.com/archives/libvirt-users/2011-July/msg00031.html

I looked this up in the OpenVZ source history at that time and vpsid
was changed to ctid at some time. So the OpenVZ driver needs to deal
with this difference as it seems that Virtuozzo is based on newer
OpenVZ that uses ctid.
