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 HV= M
domains without PV drivers (e.g. via emulated hibernation). Perhaps the
Remus guys know?

Remus works with HVM domains via normal xenstore base= d suspend/resume.
Only PV-HVM support is "disabled" for the mo= ment.

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

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