Hmm, maybe I'm not clear on what you are asking. If you are trying to recreate
your virtual machines, and you have the LVM volumes in place, just do

virsh define <xmlfile>

If you mean that you're host crashed while your guests were running, there
isn't much you can do except try to restart your VMs and see what happens.
