Test Day:2009-09-17 Virtualization VT-d

What to test?
This part of today's Fedora Test Day will focus on testing the KVM PCI Device Assignment feature added in Fedora 11.

Since several improvements have been made to the feature since Fedora 11 and it is very closely related to the SR-IOV feature in Fedora 12, it is worthwhile re-testing the feature.

If you come to this page after the test day is completed, your testing is still valuable, and you can use the information on this page to test VT-d and provide feedback.

Who's available
Mark McLoughlin is your host for today.

The following people have also agreed to be available for testing, workarounds, bug fixes, and general discussion:


 * add your name here

What's needed to test

 * A fully updated Fedora 12 Rawhide machine. See instructions on the main test day page.
 * At least one guest image installed before the test day (suggested reading - Virtualization_Quick_Start)
 * A host machine which has Intel VT-d or AMD IOMMU support

Test Cases
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

$> virsh nodedev-list --tree computer |   ...    +- pci_8086_10bd |  |    |   +- net_00_13_20_f5_f9_5a ... $> virsh nodedev-dumpxml pci_8086_10bd pci_8086_10bd computer  0      0       25       0       82566DM-2 Gigabit Network Connection Intel Corporation

Follow each of these test cases:


 * 1) libvirt nodedev operations
 * 2) assigning a device using libvirt
 * 3) assigning a device using virt-manager
 * 4) virt-install --host-device
