libvirt users - Mar 2013 - managedsave results in unexpected shutdown from inside Windows

Hi,

I'm facing a strange behaviour of windows 2008 guests. After a virsh
managedsave and start, the windows guest open a "unexpected shutdown"
window.

The window looks like this one (randomly taken from the web):

  http://toastytech.com/guis/srv2k3login2.jpg

This happens in all virtualized windows in a hypervisor.

Has anyone else experienced such issue?

Thanks,

 if a windows2003 directly poweroff (not normal shutdown),then this window
will open when bootup.

That shouldn't be happening - a start after a managedsave should be
restoring the guest to the same state as at the save.  It sounds like
you may have run into a corrupted managedsave file, so libvirt punted
and booted the guest from scratch instead of restoring state; booting
from scratch without a clean shutdown would explain the symptoms of the
OS complaining.

Did you upgrade qemu in between when you saved your guest and restarted
it?  If so, this may be more of a qemu bug about not handling incoming
migration of data generated from an older qemu.  Are you sure that the
managed save data was not corrupted, such as a power outage occurring
before the managed save file was completely flushed to disk?
