Thanks for the suggestion.

Another one, although I'm sure that some will loudly protest about it :-) I've had excellent results with rsyncing the complete content of Xen VMs to other Xen VMs. It works flawlessly even for MySQL database in full swing. Maybe it makes a difference if you use InnoDB, I'm using MyISAM whereever I can for reasons of speed and robustness. I've rsynced even heavy use servers with no problems (did a lot of tests to make sure the results worked). Before doing it this way I checked out the LVM snapshot options (e.g. mount a snapshot and rsync that snapshot) as this is usually recommended but found them not really fitting me.
