Are the instructions for passing a device at: http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM supposed to work for passing one of four onboard nics to a guest? I ask because not only did it not work, it made my server a very unhappy camper. Server: HP DL380 G6, 1 E5540, 6 GB RAM (3x2), latest BIOS SMT enabled, VT-d2 enabled Host OS: Fedora core 9 OS, kvm.git 66b0aed4a9e15..., pxe booted Device is last of the four on-board nics (the host is using the first one). Commands: modprobe pci-stub echo "14e4 1639" > /sys/bus/pci/drivers/pci-stub/new_id echo "0000:03:00.1" > '/sys/bus/pci/devices/0000:03:00.1/driver/unbind' echo "0000:03:00.1" > /sys/bus/pci/drivers/pci-stub/bind Those commands worked fine. At this point I tried to mount the 4th logical disk (host OS is run via pxe and automounting of drives is not setup) and it failed. Since that disk holds the guest I wanted to run, I decided to reboot and start fresh. During reboot the server hung after a few BIOS initialization screens but before the PXE attempt. There was a 1 line message on the screen about an unknown NMI. The IML for the server shows a couple of critical errors - description is "Unknown Event (Class 6, Code 4). A second reboot attempt hung at the same place. I had to disable VT-d2 in the BIOS to get it to come back. Any ideas? david -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
