Note the error message. It takes more to assign a device to a guest than just asking for it in virt-manager. First your hardware has to be capable of it. Then you have to add the proper options to your kernel commandline to enable it. And if you want to use VFIO device assignment (which is much preferred if you're running F20 or better) you will need to make sure the vfio-pci kernel module is loaded. This (slightly outdated, because it doesn't reference VFIO) guide describes some of that: https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Host_Configuration_and_Guest_Installation_Guide/chap-Virtualization_Host_Configuration_and_Guest_Installation_Guide-PCI_Device_Config.html Beyond that, if the device you're assigning is a virtual function (VF) of an SRIOV-capable network card, you should read this: http://wiki.libvirt.org/page/Networking#PCI_Passthrough_of_host_network_devices I'm preemptively closing this bug. If you still have problems, please ask in IRC on #virt (irc.oftc.net) or send email with details of your hardware and kernel commandline to libvirt-users before re-opening. (In the end, it is possible that assigning your selected network device to a guest simply isn't possible.) |
Description of problem: After create a Fedora 20 VM and attach a PCI device which is a NIC in virt-manager and start VM I receive this errors: Error starting domain: internal error: process exited while connecting to monitor: qemu-system-x86_64: -device pci-assign,configfd=26,host=3f:00.0,id=hostdev0,bus=pci.0,addr=0x9: No IOMMU found.
