Checkpointing should work with the current code in 3.1 for both HVM and
PV domains. Previous versiosn should support PV domains but not HVM.
The command for this is "xm save -c domid_or_domname savefile"
To restart a checkpointed domain, you use "xm restore savefile".
I say should, as this is not something I have tested in itself. However,
I'm quite sure that it works, as checkpointing is essentially the same
as a save, except that after the data has been saved, instead of
"removing" the guest, it's "unpaused".
Have you tried it, and if so, did it work?
[Note of course that the disk-content on such a saved domain isn't
guaranteed to be consistent, so you may want to "snapshot" the diskimage
at the same time.
