[fedora-virt] Virtualization Test Day

Thu May 7 22:52:29 UTC 2009

Hey,
	Okay, I think we made heaps of progress today. To give you an idea of
what went on today, see below for the list of bugs that were filed
during the test day.

	You can also take a peak at the wiki:

  https://fedoraproject.org/wiki/Test_Day:2009-05-07_Virtualization

	for results from people's testing. I especially like the Guest Installs
page:

  https://fedoraproject.org/wiki/Test_Day:2009-05-07_Virtualization_Guest_Installs

	Thanks to everyone who got stuck in, but I thought it would be nice to
credit the people who filed bugs ... so, from a quick query:

      7 clalance
      6 markmc
      5 berrange
      4 mtosatti
      4 jlaska

	No doubt the testing will continue and there'll be a bunch more bugs in
my inbox in the morning :-)

Thanks again,
Mark. 

Device assignment:

  https://bugzilla.redhat.com/499614
    System locks up when booting with "intel_iommu=on"

    A report from Fujitsu that intel_iommu=on locks up one of their
    machines at boot. Likely a BIOS bug.

  https://bugzilla.redhat.com/499637
    IOMMU: no free domain ids

    Looks like a DMAR domain ID leak in the kernel.

  https://bugzilla.redhat.com/499261
    KVM PCI device assignment fails with
    "assigned_dev_register_regions: Error: Couldn't mmap 0xffa40000!"

    This turned out to be libvirt interpreting managed=yes
    incorrectly.

  https://bugzilla.redhat.com/499678
    libvirt should be able to reset a PCI function even if it causes
    other unused devices/functions to be reset

    libvirt's PCI reset logic needs work. Not trivial.

  https://bugzilla.redhat.com/499561
    libvirt does not automatically re-attach an assigned device in the
    host after guest shutdown

    Should be fixable.

  https://bugzilla.redhat.com/499386
    libvirt's qemu driver interprets the <hostdev> "managed"
    attribute incorrectly

    libvirt was treating managed=yes as managed=no.

  https://bugzilla.redhat.com/499708
    SELinux blocks libvirtd sysfs writes for
    virNodeDeviceDettach()/Reattach()/Reset()

    Fixed by latest selinux-policy.

  https://bugzilla.redhat.com/499259
    svirt denials breaks KVM PCI device assignment

    Not trival to fix correctly.

  https://bugzilla.redhat.com/499267
    Assigning a PCI device using virt-manager/virt-install fails

    virtinst's code to detach/reset the device before starting the
    guest was broken. Cole cooked up a patch to fix it.

  https://bugzilla.redhat.com/499352
    Re-enable CONFIG_DMAR_DEFAULT_ON

    Somewhere along the way, DMAR got disabled by default. Even though
    the original issue was fixed, it didn't get re-enabled.

VNC Authentication:

  https://bugzilla.redhat.com/499589
    virt-manager console widget doesn't know how to collect a 'username'
    for authentication with VNC

    virt-viewer doesn't know how to provide a username/password to
    libvirt connections

  https://bugzilla.redhat.com/499595
