Re: [Xen-users] VGA Passthrough / Xen 4.2 / Linux 3.9.2

Aloha Gordon,

When you say "BSOD on subsequent start-ups," are you saying that on the boot after AMD driver installation your system BSODs?  How do you manage to get around that, by simply restarting the host?

I believe I finally figured out what miraculously made things work: I
reduced the domU memory from 8GB to 2GB.

With 8GB it BSODs at startup.

With 2GB it "just works".

Now on to fighting the more minor issues (none of my USB devices work
after domU reboot, ejecting them doesn't help) and the issues that
everybody else is having (BSOD on subsequent domU start-ups after
shutting it down once).
