Revision as of 14:01, 7 May 2009

See Test_Day:2009-05-07_Virtualization.

This test area is concerned with testing the KVM PCI Device Assignment feature added in Fedora 11.

Known bugs include:

  • 499259 - svirt denials breaks KVM PCI device assignment
Until this is fixed, all but the nodedev ops test case requires you to run SELinux in permissive mode
  • 499352 - Re-enable CONFIG_DMAR_DEFAULT_ON
You will need to boot the host with intel_iommu=on until this is fixed
  • 499267 - Assigning a PCI device using virt-manager/virt-install fails
Fixed in python-virtinst-0.400.3-8.fc11
  • 499386 - libvirt's qemu driver interprets the <hostdev> "managed" attribute incorrectly
Fixed in libvirt-0.6.2-6.fc11
  • 499561 - libvirt does not automatically re-attach an assigned device in the host after guest shutdown
Workaround is to run virsh nodedev-reattach after the guest has shut down

Prerequisites

In order to test KVM PCI device assignment, you need:

  1. a host machine which has Intel VT-d or AMD IOMMU support
  2. the host booted with intel_iommu=on in order to enable VT-d support
  3. SELinux in permissive mode
  4. At least libvirt-0.6.2-6.fc11 and python-virtinst-0.400.3-8.fc11 installed

Please upload your smolt profile using smoltSendProfile and add its URL to the table below.

Also, it would be useful to post your PCI bus topology - e.g. post the output of lspci -t -v to Fedora's pastebin.

Tests

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
  <device>
    <name>pci_8086_10bd</name>
    <parent>computer</parent>
    <capability type='pci'>
      <domain>0</domain>
      <bus>0</bus>
      <slot>25</slot>
      <function>0</function>
      <product id='0x10bd'>82566DM-2 Gigabit Network Connection</product>
      <vendor id='0x8086'>Intel Corporation</vendor>
    </capability>
  </device>

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

Results

If you have problems with any of the tests, file a bug report in bugzilla.
