Dear all, does anybody know if it is currently possible to do GPU passthrough in kvm? I have access to a dual Quadro 4000 setup and I would like to pass the second one to kvm for use in a VM.
I read a lot on internet and it seems feasible [1, 2, 3] and there is even a reported success case [5].
However when I start the VM the host reboots with PCIe error 928: Completion timeout.
My current setup is:
* Fedora 18 with 3.9.4-200 x86_64 * dmesg | grep -e DMAR -e IOMMU shows that they are both enabled * nvidia driver installed from rpmfusion * I use vfio assignment as per [4]
Thanks and regards,
Mario
