AFAIR with Xen 4.3.0, Xen has to be patched with

wget ftp://ftp.enjellic.com/pub/xen/xen-4.2.0.ati-passthrough.patch -O - | patch -p1

Install xen (make & Co).

This patch below was sent to Xen mailing list a couple months ago. It should prevent you from getting error code 12.

Download the following script to manage domU.

Update it to your own needs.

When installing AMD driver avoid to install Catalyst Center -- to avoid blue screen.

I did it several time with my HD 7970 and it worked perfectly.

Is it possible that this patch was already included in the Xen source I downloaded about a week ago? It turns out that I was only getting code 12 when using the wrong qemu, so I guess it was being passed using standard pci passthrough.

Catalyst Center is installed now, and the problems I'm having are mostly not blue-screen-related. I'll remember that next time I'm installing it though.

Hello Toby,

Glad it's working!

I recall reading that the problem where a CCC install would bork the VM with a 100% chance was solved somewhere between the 12.x to 13.0 Radeon drivers.  Still, I've seen *some* VMs behave well and others fail spectacularly.  I never got it to the point where I was satisfied what the cause is, but the general rule I follow now is:

1) install bare driver, reboot host.

2) create a restore point (or snapshot the VM disk), then run the install again and install CCC (or VISION or whatever the name is now :P)

Just a note for reference and any stray, future googlers!

Cheers,

Andrew
