We should make use of this --name parameter then - I guess it didn't
exist when we first wrote the driver. It is useful to users to have
separate ID vs Name parameters - and in fact the current reusing of
'ID' for the name, causes a little confusion in virsh's lookup routines
because it can't tell whether the parameter its given is a name or an
ID, since they are identical.

There is still a question of how to specify both a name and CTID in XML description.
By default, CTID can be obtained as openvzGimmeFirstUnusedCTID(), but actually
I think that there exists a number of persons interested in giving CTIDs manually.
