* [https://bugzilla.redhat.com/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]
: There is no workaround for this; this affects the virt-manager and virt-install test cases

* [[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

In order to test KVM PCI device assignment, you need:
In order to test KVM PCI device assignment, you need a host machine which has Intel VT-d or AMD IOMMU support.
 
# a host machine which has Intel VT-d or AMD IOMMU support
# the host booted with <code>intel_iommu=on</code> in order to enable VT-d support
# The <code>virt_manage_sysfs</code> selinux boolean enabled - <code>setsebool virt_manage_sysfs on</code>
# At least [https://koji.fedoraproject.org/koji/buildinfo?buildID=101058 libvirt-0.6.2-6.fc11] and [https://koji.fedoraproject.org/koji/buildinfo?buildID=101049 python-virtinst-0.400.3-8.fc11] installed

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
