I only tried the nvidia card because some people found success with rather old drivers.
The problem I'm having is as follows:
I have one monitor plugged into my onboard graphics, and another plugged into the AMD card.
Now, when I have the AMD card set as the primary graphics card, I dettach it and the screen goes black.
It does not automatically switch over to the other graphics (integrated). Sometimes I'll get what looks like Zen console output.
As such, I've been booting my computer with my onboard as the main, and working it that way, but as stated the drivers are giving me blue screens.
Not sure if this information is relevant or not. If i'm reading the guide correctly, it should switch over to onboard right?
I just made 2 new USB's with Fedora and Linux Mint.
Going to try fedora first. If I get immediate success, i'll just use that. Otherwise I'll install mint and use that until I can find the problem (Since i prefer mint).
I'll be posting in this thread later tonight with my initial success/failures for fedora. Thanks for the help so far guys.
OK, my setup is slightly different, using only one screen. However, what you describe seems perfectly normal, i.e. your screen going blank when you detach it.
I am not aware of any mechanism that can make Linux switch to another GPU after you detach it from the initial graphics adapter.
You already pointed to the right direction:
1. Use your integrated GPU (in the 3570) as your primary graphics adapter for Xen / Linux.
2. Blacklist the driver for the secondary graphics adapter - the one you are going to use for Windows. This may not be necessary, but in my case the driver got in the way with detaching / assigning it to the Windows domU.
3. Try the AMD card first, as you got more chances for success.
4. Install Windows domU
5. After 2 Windows domU reboots, your Windows installation should be ready to install the graphics driver for your AMD graphics adapter. At this point you are still working with virt-manager and a VNC screen.
5a. Open Device manager and go to the graphics adapter section. You should have two cards listed, one with a yellow triangle. Right-click the one with the triangle and install the driver.
When doing my installation with the Nvidia card, I went to the nvidia website and let it discover my card and download the correct driver. Perhaps ATI has a similar feature on their website. Try the latest ATI driver for Windows 7 (or whatever Windows you install). Windows will probably need another reboot.
5b. After the reboot you should be seeing the initial boot sequence in the virt-manager VNC screen, until the driver loads and switches to the actual graphics card (your ATI or Nvidia card). Make sure your second screen is connected and working. The Windows login screen should appear on your second (physical) screen.
5c. In case Windows BSODs here, there is a driver issue or an issue with the graphics card - it may not support VGA passthrough. One last thing to check: Make sure VT-d is enabled (in your BIOS) and working.
