[plug] LVM on Linux

Natch, the link now gives a 404. In any case, I was reading it as a 
precursor to asking a question, so I'll just ask the question:

Does anyone know if you can create an LVM2 snapshot, muck around with 
the partition (well, entire Xen VM in this case), then revert any and 
all changes? I do it regularly with my VMWare Server test VM. Hmm, what 
about using Xen somehow for that purpose, rather than the underlying LVM 
partition? FYI I'm very new to Xen.

Searching hasn't been promising...
"Unfortunately, open source Xen doesn't offer support for snapshots"

It looks to me that I'll have to create an lvm-snapshot (or turn the 
machine off) then dd a copy of the VM. When I'm done, a 'revert' is 
simply deleting the copy.

Any better ideas?
