Logged generalz Sr. Taylor 1,149817 1 Are you sure your BIOS really supports IOMMU. An add-on device or on board > device? http://www.linux-kvm.org/page/How_to_assign_devices_with_VT-d_in_KVM? Unable to assign device "hostdev0" Summary: NIC passthrough failed: No IOMMU found.
They’ve got answers. Unable to assign device "hostdev0" seems to suggest that your hardware doesn't have an IOMMU, or it is not configured correctly. If I use virt-manager to add the wireless card as a PCI device, without first detaching it with virsh nodedev-detach (as mentioned above), then I get an error message from virt-manager Unable to assign device "hostdev0" Failed to deassign device "hostdev0" : Invalid argument qemu-kvm: -device pci-assign,host=02:00.0,id=hostdev0,configfd=23,bus=pci.0,addr=0x7: Device 'pci-assign' could not be initialized ' Expected results: NIC can be passthrough to guest
I have never had it not work for me if I get that far. Notice this also apply to the devices which only support MSI-X. Build the kernel make make modules_install make install 3. This site is not affiliated with Linus Torvalds or The Open Group in any way.

Taylor Sep 24 '14 at 20:13 Actually, I just found out that this processor supports VT-x but not VT-d, so I can't do IOMMU. –J.

Perhaps we should show whether IOMMU is enabled with 'xl pci-assignable-list ' to let user know more earlier. > > OK, I think this patch is probably still a good thing
Your config file looks good, the configuration of pciback looks good.One quick thought, please post the output for the 04:00.1 device from the following command. Instead, it is partially assigned, and after the failure is not available to be assigned to another guest. Why did the best potions master have greasy hair? CONFIG_DMAR_DEFAULT_ON is not set.
In order to use PCI passthrough, the CPU must support IOMMU/VT-d.If you get no output from that grep -E command, hardware virtualization support isn't available or configured correctly.Check your BIOS is Version-Release number of selected component (if applicable): virt-manager-0.8.4-4.el6.noarch How reproducible: always Steps to Reproduce: 1.
