Shutdown/restart bug

Shutdown/restart bug

I've been having some problems with Windows HVM domains not shutting down
cleanly.  I have the latest GPLPV drivers installed... although that
doesn't appear to be related.

The symptoms are exactly like this bug and it only occurs with xl.
http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1769

In addition to that, it only seems to occur with a secondary graphics card
being passed through.
I end up with a null domain that I can't shutdown.

Killing the qemu-dm process with kill pid sorts that out though.

I'm running dom0 kernel 2.6.32.50.

I think that was a bug with Xen. Have you tried to upgrade to the most
recent version?

I don't recall that having an impact, but maybe it did..
Do you see the problem if you are running with the 3.3 kernel?

Konrad, thanks for the reply.

No I haven't tried the latest Xen. It'd be good to test that just to see
whether this bug is still there.
Also kernel 3.3 would be worth trying.
I'll get onto this next week and feedback.

I've seen "zombie" VMs hanging around after passing a device through
as well.  Xen reports that there is an outstanding reference to one of
the domain's pages.  It's fairly short on my to-do list.  I'll send
you an e-mail when I've got it fixed at my end, and you can see if it
fixes it for you as well.

P.S.: FYI, the convention on xen-devel is to reply in-line, not to
top-post. :-)  (Catches me out sometimes too.)
