http://linux-vserver.org/Vserver+DRBD looks promising, since 90% of the changes will be made in the vservers on the node
The HowTo tells how to give a vserver its own partition, and use drbd to keep this in sync over 2 nodes.
Would it also work to mount the DRBD device as /var/lib/vservers, instead of /var/lib/vservers/<vserver-name> , and hereby take all vservers in 1 go?
