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?

Remus works with HVM domains via normal xenstore based suspend/resume.
Only PV-HVM support is "disabled" for the moment.

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

Yes. the logs would be great. Also, by frozen, do you mean the domain remains
in "suspended" state? or is Windows hung?
