Re: [Xen-users] vga passthrough help needed.
I didn't apply any patches just used the stock Debian 4.1.3 package.
As I said I have pretty the same GPU... and it works.
Though I too had the domU Win8 crashing when trying to install Catalyst 12.8 and 12.9. Worked around the issue by extracting the files and installing the drivers through Device Manager point to the extracted files directory.
I should noted that Win8 was installed via VNC, updated
.cfg with PCI devices used gfx_passthrouh=0, booted to Win8, defined the HD5450 powered screen has the primary display and then proceeded to install AMD driver - though the VM worked just fine with MS supplied drivers.
