I was following instructions described in this KVM document: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM When I get to the unbind step: echo 0000:01:00.0 > /sys/bus/pci/devices/0000:01:00.0/driver/unbind In Raring I got a kernel Oops. Please note at this point I am not running the kvm guest, just trying to unbind the PCI device. I do have VT-d enabled in the bios and a processor that supports IOMMU. This problem is repeatable and appears to be isolated to the unbind command. However, in Saucy, I do not get a kernel oops, but executing unbind as root puts back into non-root user account. After going back as root, I am not able to perform the next step to bind the device. root@ubuntu:/home/ubuntu# echo 0000:01:00.0 > /sys/bus/pci/drivers/pci-stub/bind bash: echo: write error: No such device ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: linux-image-3.8.0-23-generic 3.8.0-23.34 ProcVersionSignature: Ubuntu 3.8.0-23.34-generic 3.8.11 Uname: Linux 3.8.0-23-generic x86_64 ApportVersion: 2.9.2-0ubuntu8.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: bruzer 2169 F.... pulseaudio /dev/snd/controlC1: bruzer 2169 F.... pulseaudio CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found.
