I don't think Roller Derby applies here. Virt-manager and virsh support VM snapshots. You could schedule snapshots with a script using virsh. But I don't know that it will create LVM snapshots, and even if it did you wouldn't want it to because they're slow. There soon will be LVM thinp support in libvirt but I don't think it's there yet. Instead, use qcow2 files for this. In my "Fedora 20 installation as a benchmarking tool" tests, the fastest installs I got were Btrfs in the guest, writing into a qcow2 file with xattr +C on a Btrfs host, with the unsafe cache setting. Even plain ext4 on an LV wasn't faster.
