Actually, an even better way (with better tools integration) would be:
xm create mydomain
xm fs_snapshot mydomain
+---> freezes domain filesystem
+---> does a block level snapshot with LVM or qcow
+---> unfreezes domain filesystem
<user now backs up the snapshot at their leisure>

It's mostly a question of Linux kernel hacking, I think, plus adding support
to the Xen tools. Xen itself would definitely not need to be touched.
I've actually been having a look at this today and trying to code up a little
example implementation. You're welcome to have a go too if you want,
particularly if you're into kernel hacking. But I'll put my code online if I
get anywhere, anyhow.

Lots of people seem to be interested in this sort of thing, so I think it's
worth looking into.
Cheers,
Mark
