Uhm, just to get clear in this topic,
the great work of James is not that useful as it supposed in this thread.
leaks reliable support for exactly those Windows Versions with best
So there is the choice to exploit Hyper-V guest integration services or
absolutely ugly hacking around in a win2008 x64 guest policies with a
great chance to get the guest perfectly and unrecoverable meshed up.
So it would be great at least to have things like shutdown notification
of the box, as it will be with an viridian interface implementation
When you say "shutdown notification" I assume you mean dom0 telling a
hvm guest to shutdown , in which case "xm trigger<domid> power" seems
to do the job with no additional drivers or services required, and
should work on most operating systems.
Perhaps I misunderstood..
Hm no it is fine but when I shutdown dom0 the windows system just get killed
(xm shutdown is issued afaik). Furthermore this won't include a back channel
Yes thats right when the system shuts down xm shutdown is called, I
don't know what happens if a guest fails to shutdown, myself I'd
probably want it to be xm destroyed after a timeout as thats probably
what I'd end up doing anyway, I could easily modify the script for you
so that after trying xm shutdown it sends xm trigger<domid> power to
any remaining domains and if any still fail to shutdown I could make
it destroy them.
Its something I looked into and could do in few minutes, I just didn't
bother because all of our servers have remote kvm and 99% of reboots
are supervised, but let me know if you'd like me to make a patch for
Would be great until a more sophisticated way is realized.
(does it work?) and not every system surely shutsdown when powerbutton is
pressed, maybe there must be a bit configured...
Again if xen provides a feature using viridian API win2008 x64 guests
use it without ANY modification.

I don't think anyone's doing that, but there is a choice of Xen PV
drivers for Windows that will do the job. Are the PV driver interfaces
even public? I don't remember seeing them in the hyper-v spec, though
haven't read the latest version.
They were implicitly published, at least to some extent, in the form of
the big HyperV PV driver dump for Linux. But I don't think those
drivers are very featureful yet, though they claim to be planning to
release more updates.
