Re: [Qemu-devel] Regarding Intel IGD passthru support for QEMU/KVM

[Raghavan Santhanam]

Hi Gerd,

Okay, thanks for the update.

By the way, it's great to see the commitment of Qemu developers in the

open-source community. Appreciate your entire team's effort right from

the the inception of QEMU by Fabrice Bellard!

Best,

Raghavan

It's in progress.  The xen code in the code base seems to have problems
though, recent testing showed that it'll only work with recent linux
kernels.  Older linux kernels and windows guest drivers do not work
correctly.  So this is not just about enabling kvm support, but also
about figuring why things are not working correctly on xen ...
