Re: [libvirt-users] is it possible to create a snapshot from a guest residing in a plain partition ?

Note that when you create an external snapshot, the partition becomes a read-only point in time (no further updates to that partition), and your new file.sn qcow2 wrapper file created by the snapshot operation stores all subsequent guest writes. (Well, unless you decide to do a commit operation to push the changes from the overlay back into the base file and get rid of the overlay) -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
