[libvirt] Ephemeral VM operation

[Dave Allan]

A number of hypervisors have a mode in which changes made to storage
are not persisted across a reboot of the VM.  qemu uses the -snapshot
flag; VMware refers to this functionality as non-persistent disk[1].  Is
this functionality something that is interesting to libvirt?
