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:
for results from people's testing. I especially like the 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:
No doubt the testing will continue and there'll be a bunch more bugs in
my inbox in the morning :-)
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.
IOMMU: no free domain ids
Looks like a DMAR domain ID leak in the kernel.
KVM PCI device assignment fails with
"assigned_dev_register_regions: Error: Couldn't mmap 0xffa40000!"
This turned out to be libvirt interpreting managed=yes
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.
libvirt does not automatically re-attach an assigned device in the
host after guest shutdown
Should be fixable.
libvirt's qemu driver interprets the <hostdev> "managed"
libvirt was treating managed=yes as managed=no.
SELinux blocks libvirtd sysfs writes for
Fixed by latest selinux-policy.
svirt denials breaks KVM PCI device assignment
Not trival to fix correctly.
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.
Somewhere along the way, DMAR got disabled by default. Even though
the original issue was fixed, it didn't get re-enabled.
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
virt-viewer mixes up password and username credentials for VNC
failure to install new kvm packages on FC10 -> FC11 DVD upgrade
Graphics crashes when vmware video card is selected
After OS install, reboot causes the guest to shutdown
32 bit KVM guest hangs enabling NX protection; booting with -cpu
KVM guest fails to boot with if=virtio; works with if=ide
Installation of guest using Network boot(PXE) is failing
Reboot fails when using qemu -kernel
[PATCH] qemu-kvm: avoid harmless unhandled wrmsr 0xc0010117 messages
info balloon is repeated in qemu log once per second
libnuma: Warning: /sys not mounted or invalid
'virsh destroy' destroys multiple VMs
VM migration fails with "TCP migration is not supported with this
libvirt VM migration fails with "error: Unknown failure"
libvirtd AVC denials - uml backend writing to /root/
AVC denial from virsh dominfo - libvirtd (virtd_t) "getattr"
Guest with source-less cdrom fails to start :: Failed to set
SELinux is preventing libvirtd (virtd_t) "getattr"
svirt error when starting guest - SELinuxSetSecurityLabel: unable
to set security context 'system_u:system_r:svirt_t:s0:c152,c660':
Hotplugging vcpus to an F-11 64-bit Xen domU doesn't work
Cannot balloon a F-11 Xen domU guest above the initial starting
F-11 Xen 64-bit domU cannot be started with > 2047MB of memory
F-11 Xen 64-bit domU stack traces when unmounting a disk
F-11 Xen 64-bit domU hangs when trying to format a fake 5TB disk
F-11 Xen 64-bit domU does not give memory back to the dom0
F-11 Xen 64-bit domU cannot crashdump
virtinst: Debian Lenny cannot handle virtio NIC
failure to add more than 16 virtio-blk devices in virt-manager
virtinst incorrectly guesses os variant from F11Preview .treeinfo
virt-manager Scaling->Always - scales the guest screen up but not
inconsistency between reported device names / guest device names in
When window focus set to click - <ctrl><alt> grabs pointer even
when virt-manager isn't focused
hot-removing in-use virtio-blk device in virt-manager should fail
RFE - include virt type in virt-manager Guest->Details tab
virt-manager should run stats refresh operation in a background
thread per connection
anaconda in a KVM guest only occupies 800x600 of a 1024x768 screen
F11Preview: anaconda writes ifcfg-eth0 with unquoted NAME parameter
