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 [1] http://www.linux-kvm.org/page/VGA_device_assignment [2] https://bbs.archlinux.org/viewtopic.php?id=162768 [3] http://samos-it.com/removedetach-a-pci-device-linux-kvm-vga-passthrgough-nvidia-quadro-2000/ [4] https://fedoraproject.org/wiki/QA:Testcase_Virtualization_KVM_PCI_Device_Assignment [5] http://tavi-tech.blogspot.com.es/2012/05/vga-passthrough-kvm-fedora-17-and.html
