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?

From the point of view of "giving options to end users" then it probably should be. To implement in QEMU/KVM, it sounds like it could be done by using a snapshot(s), plus nuking the snapshot when the vm is shut down?
