Ubuntu – KVM-Guest does not boot: qemudParsePCIDeviceStrs

kvm-virtualizationlibvirtlvmUbuntu

I have a Server running Ubuntu 10.10 Server-Edition kvm, and libvirt (both ubuntu-native packages)
HDD-Partitioning was done with LVM. Then I created some VMs with Virt-Manager and assigned LVM-Volumes to the VMs.

Now the VMs do not boot. Virt-Manager shows a CPU-Usage of 100% for this Guest and the VNC-Connection states

Booting from Hard Disk

The VM-specific logfiles do not show any abnormality only syslog shows a warning

warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed

What can I do to find the error?

Can you try stopping AppArmor "sudo /etc/init.d/apparmor stop; sudo /etc/init.d/apparmor teardown"

then restarting the VM!
