Just as long as you realise that your "backups" are in fact almost
certainly corrupted to some extent or other. Wether that is an issue
for you depends heavily on the type of operations your DomU does. If
it's "write-little" and has journalled filesystems then it's probably
not serious. If it's "write-heavy", and especially if it runs
applications that do their own caching (like DBs), then it could be
more serious.
Your snapshot has a state somewhat akin to what you'd have if you
just yanked the power cord on a bare-metal server.
