[Xen-devel] VT-d issues

["Kamala Narasimhan" <Kamala.Narasimhan@xxxxxxxxxx>]

I tried VT-d pass-through with the latest xen-unstable and encounter the
following issue(s) -

1) When I pass through a network adapter (doesn't matter which kind),
while I see the device within guest OS (tested with Vista and XP guest),
I encounter a machine reset when the driver for the passed through
network adapter is being installed (either through plug and play or by
manual installation).  I have attached information about the system in
question.  Has anyone tried pass-through on a system with the exact
configuration provided in the attachment (including stepping; Note -
network pass-through works on a machine with almost similar
configuration except for stepping # difference)?  Also, attached is bug
check info if that is useful.
2) On a different machine, I encounter a bugcheck similar to the one
entered in http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1244
only when I shutdown a domain that pass-through a Intel 82566DM-2
network adapter.  As the bug report wasn't specific about the device
that is passed through when the machine reset happens, thought I would
mention in case this helps narrow down the problem.

Thanks,
Kamala
