GPGPU passthrough in linux kvm

GPGPU passthrough in linux kvm

[Adhyas Avasthi]

I read an old email thread which talked about GPGPU passthroughin
linux-kvm. Was this implemented?

If not, are there some quick hacks I can use to enable it in my tree?
Right now, I try to follow the same commands as I do for NIC
passthrough, but it complains that my device is busy. I have two
NVidia Graphics cards on my box.

I'm working on it. It doesn't work because graphics cards have BIOSes.

I need to debug some issues with the BIOS of my 9600GT, but I think
I'm quite close to succeed.

Are you still working on implementing this feature?
Did you make some progress in debugging the BIOS issue?
I am still very much looking forward to kvm being able to pass a video 
card to a VM.

hope you soon have success so kvm can do GPU passthrough

we can not let xen be the only one who can do this see beta XenServer 5.6
now with GPU passthrough
