[libvirt-users] libvirt, snapshots, LVM, and existing VMs

Hello, I am running libvirt 0.8.3 with a couple VMs using a LVM VG that I had previously setup on my host. I did not use the storage pool functionality of libvirt to create the VG in the first place ('pool-list' is empty). Now I want to be able to take snapshots of the VMs. Having read this previous post [1] on the mailing list, I gather that libvirt does indeed support taking snapshots of VMs on an LVM. I suppose I need to create storage pool that includes the <backingStore> element. However, I am not sure how to go about creating this pool and making my existing VMs utilize it. Is what I am trying to do even possible? If so, what is the proper way to go about doing it? Best, Casey Link [1] http://www.redhat.com/archives/libvir-list/2009-February/msg00196.html
