i don't even bother creating the destination vserver if it will be a mirror of
the original, i simply rsync /etc/vservers/* and /vservers/*.

we do that every 6 hours to update files that have changed, or add new guests
with no problems. you will see 'file vanished before copy' and 'ignoring
socket' errors, but they are nothing.

we use rsync -a --perms --delete <and the rest of the copy line>

if i install a new guest, when i wake it is on the mirror server ready to go.
and yes i have tested the new copies and they run as perfectly as the
original ones.
