Re: [Xen-users] Intel IGD passthrough in xen 4.4

[Reinis Veips <reinis.veips@xxxxxx>]

Hi Andre,

I just tried a fresh installation of Win7 (I may have started the previous
install without qemu-xen-traditional), but I am still unable to get it working.

I did install Intel drivers in domU, but there is still no video output.

I also realized that I need to pass through (or at least hide from dom0)
 CPU's integrated audio controller (otherwise alsa on my dom0 wasn't too happy).

The latest config I am using is- do you notice anything out of the ordinary?
