Hi Mats,
Thank You for the answer. Yes, it is Windows on HVM. With linux as domU it
works OK. So it is clear.
I have also the problem with the shutdown of such windows domain - the VM is
always "turned off", so Windows are not shut down correctly (again, with
Linux as domU it is no problem).
What would You recommend, is there any possibility to get this both
functionalities working for windows (also not with HVM), could You point me
to some description how to configure it to get it working? Or is the only
chance to wait for xen 3.0.5 or maybe later?
Thank You very much for response,
Archie.

Does vm_w2ksrv_01 mean that this is a Windows guest -> a HVM guest? In
that case it's not "supposed to work". The code to implement HVM
save/restore was introduced into unstable a few weeks back. It works
most of the time at present, but there are a few bugs to fix still - in
particular, fixing that a domain may be in the middle of a IO
transaction when it gets stopped - the current code in xen-unstable
isn't coping with this very well... There is work in progress to fix
this... I think this is a "required" feature for 3.0.5, so 3.0.5 should
have working save/restore - Live migration may or may not be included in
that.
