You can do it your way - but you've got to shutdown the domu before

be able to dump a running domu-filesystem-image after calling
xfs_freeze
(inside the domu). However, I wouldn't recommend using XFS as root
filesystem.
The other option is to use some kind of network backup client in
your domu
or tar/cpio/dump all necessary partitions somewhere.
I just tar all my domu's root-partitions into a network filesystem
directory.
I use LVM, and a script running in dom0 I knocked up to create
snapshots of
each running domU in turn, then rdiff-backup to send the data off
somewhere
else.
Hi Mike,
I'd read about problems with LVM snapshots on earlier 2.6 kernels and
didn't immediately turn up anything that indicated it had been
resolved. Any issues to watch out for or has it all been relatively
plain sailing for you?
