| Known bugs include:
| |
|
| |
| * [[rhbug:499259|499259]] - svirt denials breaks KVM PCI device assignment
| |
| * [[rhbug:499708|499708]] - SELinux blocks libvirtd sysfs writes for virNodeDeviceDettach()/Reattach()/Reset()
| |
| : Until this is fixed, all but the nodedev ops test case requires you to run SELinux in permissive mode
| |
| * [[rhbug:499352|499352]] - Re-enable CONFIG_DMAR_DEFAULT_ON
| |
| : You will need to boot the host with intel_iommu=on until this is fixed
| |
| * [[rhbug:499267|499267]] - Assigning a PCI device using virt-manager/virt-install fails
| |
| : Fixed in [http://koji.fedoraproject.org/koji/buildinfo?buildID=101049 python-virtinst-0.400.3-8.fc11]
| |
| * [[rhbug:499386|499386]] - libvirt's qemu driver interprets the <hostdev> "managed" attribute incorrectly
| |
| : Fixed in [http://koji.fedoraproject.org/koji/buildinfo?buildID=101058 libvirt-0.6.2-6.fc11]
| |
| * [[rhbug:499561|499561]] - libvirt does not automatically re-attach an assigned device in the host after guest shutdown
| |
| : Workaround is to run <code>virsh nodedev-reattach</code> after the guest has shut down
| |
| * [[rhbug:499637|499637]] - IOMMU: no free domain ids
| |
| : This may happen after a lot of testing; workaround is to reboot the host
| |
| * [[rhbug:499678|499678]] - libvirt should be able to reset a PCI function even if it causes other unused devices/functions to be reset
| |
| : multi-function PCI devices without Function Level Reset (FLR) can't currently be used; more code to handle this case is required in libvirt

| The first thing you need to do is choose which PCI device on your KVM host that you will use for testing. Probably the most obvious to test with is a NIC. You'll need the device's nodedev name, and you can find this with
