It can, but not much :) I recently reverted the GNOME Boxes change
that installed guests with uefi. I wrote a [humorous] commit message
about it with a few details
Long story short, Libvirt/qemu don't seem to be able to perform AND
revert to snapshots of UEFI guests.
Yeah, that's a pretty frustrating bug that's been causing pain for countless
years. The main problem is at the QEMU level, because its "savevm" command
does not provide any way to mark certain block devices as skipped/ignored.
Conceptually, fixing that problem is easy, but it has come up against the
fact that "savevm" has a pile of other problems in QEMU. Any suggestion to
fix the easy problem has ended up blocked by requirement to fix the hard
problems. I think this is a mistake on QEMU's part - given that no one
has made any serious proposal to fix the hard problem in 10 years, it is
unreasonable for QEMU to block fixes for the easy problems.
Unfortunately getting someone motivated to fix any of this is hard as the
big mgmt tools like oVirt and OpenStack don't care about internal snapshots,
instead using the more general external snapshots.
It is all rather an unpleasant mess :-(
