Is there a means of snapshotting before you start up xen, and then
reverting after you shut it down?

Does anyone knows if Xen and KVM support snapshots (regardless if
Libvirt provides the API for them).
It's currently on the Xen to-do list, but apart from some research
papers I'm not aware of them implementing it. Perhaps recently.
Checkpointing is tricky to get right because you have to take a
snapshot of the memory and disk at exactly the same moment.
Note that neither Xen's live migration nor the domain save features
are real checkpoints, because they both only consider the memory.
If yes, will libvirt add API for it?
If it's supported, then why not.
