I heard the good news you published from Xen Maillist.That
really inspired me. Recently i was working on vt-d graphic passthrough
experiment. That was a real tough job for me. I faced some problems that you
may also met before. So i hope you can give me any advises or informaitons.
Any reply appreciated!
HardWare: Q35 matherboard + PCIE NVIDIA 9400 + PCI
ATI R128 + IGD Intel
Two Monitors connected with respective
cards
OS : Domain0 (Gentoo X86_64 2.6.28)
DomainU (Ubuntu i386 / windows xp /
RedHat Ent4.5)
Xen3.3.1
At first ,I assumed the Matherboard integrated graphic card for Domain0 then
passthrough the PCIE NVIDIA graphic card for DomainU.
But My Matherboard cann't support those two cards work together.
And Everytime i use the PCIE card render for Domain0, the
VT-D can't be Enable Because of the RMMR incorrect.
See:

Use this work around and (/* the whole “if”
section */) and recompile Xen
I think VT-d is needed for this to work …
Considered that reason , the PCIE card was aborted in my experiment.
Now I use the integrated card as the primary card ,the ATI PCI graphic card as
the secondly.
Now i face the problem is
that the DomainU asigned the ATI card can't displaied on the Monitor connected
with the ATI card.
