Hello,
i was able to passthrough an AMD 7870 videocard to my win7 guest
machine.
Would you add it to http://www.linux-kvm.org/page/VGA_device_assignment?
sure, i will prepare something
my host is ubuntu 12.04 with stock kernel.
my system contains:
dq67sw q67 mainboard
i5-2400s cpu
sapphire 7870 amd videocard
xonar d2x (problems to passthrough)
for full functionality i just needed two options
- kernel : iommu=on
- kvm module: ignore_msrs=1
(if i would not set it the guest os would crash with a bluescreen)
Can you report (=> kernel log) which MSRs are unknown to KVM?

i hope thats the info you need, i booted it with ignore_msrs=1 since
if i dont do that i get less output.
(do you need it without the "option"?)
the unigine benchmark ran flawlessly
also the benchmark included in windows gave my videocard
similar values (7.7) comparable with my native win7 (7.9)
now to my questions...
1. is it possible to reset the videocard properly to be able to
reboot the vm?
Which versions of kernel and qemu-kvm are involved via your distro? Can
you retry with latest Linux (3.5-rcX) / lastest qemu-kvm? Maybe
something got fixed meanwhile.
In general, there are many adapters that require special procedures to
perform resets. This one may fall into that category as well.
i will do a test today.
2. the xonar d2x is a very nice audio card, it would be very handy
to be able to use it in the vm. in my oppinion the card is a
d2 with a pci-e to pci bridge.
i tried to passthrough the card alone and with the pci-bridge
that was shown though lspci, but i had no success.
maybe you guys here have an idea on that topic?
Any further details about the error? Does the adapter work with a Linux
guest or provide more information that way?

Perhaps you are assigning a device that shares an IRQ with another device?
