I think he means this:
http://wiki.xen.org/wiki/Remus

<quote>
Remus provides transparent high availability to ordinary virtual
machines running on Xen. It does this by continually live migrating a
copy of a running VM to a backup server, which automatically activates
if the primary server fails. Key features:

The backup VM is an exact copy of the primary VM
(disk/memory/network). When failure occurs, the VM continues running
on the backup host as if failure had never occurred.
The backup is completely up-to-date: even active TCP sessions are
maintained without interruption.
Protection is transparent: existing guests can be protected without
modifying them in any way.
