As n subject, is there a safe way to "hot" copy the VMs based on files. The
best is using LVM Snapshot, I guess, but what if I can't for other reason?


to be safe, it has to be an 'atomic' copy from the point of view of
the guest.  in fact, it has to be both atomic and synchronous with a
copy of the machine state.


What do you mean with "atomic" copy?

Thanks,
Jan
