Do you have pv drivers installed which support checkpoint suspends? I'm
not sure if such a thing even exists for Windows.

I'm also not entirely sure that checkpointing was ever supported for HVM
domains without PV drivers (e.g. via emulated hibernation). Perhaps the
Remus guys know?

/var/log/xen/xl-<domname>.log. You can also do "xl -vvv <command>" to
get some additional debug output.
