Thanks! The vanilla snapshot-create-as and revert commands work just exactly the way I’d
want them to. I’d gotten a bit confused by the documentation and went down a rabbit hole
with external snapshots.
Is there any way to make the snapshot and restore faster, like maybe by a decimal order of
magnitude? For example, will PXE booting the VM and running it entirely off of a RAM disk
and also using a RAM disk for the backing store help?

According to this page:
https://wiki.libvirt.org/page/Snapshots
It saves complete memory state, or crash-consistent disk state, but not both.
You probably want to test it thoroughly and see how it does. I only use the
disk-consistent snapshots.
