Re: [Xen-devel] one video card - can I PCI-pass-through to DomU?

Hello guys,
first want to say that I've been a happy user of Xen for about 6
months already - replaced bunch of old servers with just 2 machines
reducing power consumption and increasing reliability at the same time
(not speaking about systems maintenance!).
But now I got a problem. In short - is it possible to "PCI
pass-though" to HVM guest the only graphical card on a physical server?
I've been running several servers with Xen (3.4.2/3.4.3) with a bunch
of VMs (both PV and HVM, Win/Linux) and it works great. Now I have one
Windows application that seems can't be virtualized due to some
graphics activity (basically lot of grids needs to be displayed and
updated - and it all in Visual Basic) - neither standard VGA or cirrus
logic modes can render it so it would perform good enough. So the idea
is to give my physical server's card to this particular VM.
I guess if I would have 2 video cards in the server passing through
the second card to HVM (windows 2003x32 server) would be not a
problem, would it? But if I only have 1 card - is it possible at all?
You can assign the only one gfx card to guest. then you need to access
host via network or serial console, etc.

Thank you,
