Bug 598272

Can you provide:

sudo virsh dumpxml $vmname
lsusb

I think I know where the error is coming from, but just want to confirm.

You can probably work around this by removing the USB device XML attached to your guest, easiest way is to use virt-manager.

Below are the virsh command output that you requested.  I did delete the USB devices from two VMs and then rebooted.  Same error this did NOT fix the problem.  I also rolled back the Virt-manager to the previous version, this did NOT fix the problem.  This appears to be related to a Python library patch.

Fix posted upstream

Is there an estimated relaese date for this fix?  I have been without a working VM for over a week now.

As mentioned in Comment 1, you should be able to work around this by removing the USB device from your guest. In virt-manager, go to the details section for your problematic VM, select all USB devices, click 'Remove' in the bottom right corner. You won't have access to the USB device, but the guest should run.

I'll be building a new libvirt package this week.

libvirt-0.7.1-18.fc12 has been submitted as an update for Fedora 12.
http://admin.fedoraproject.org/updates/libvirt-0.7.1-18.fc12

I have now upgraded to FE-13 and cannot use a USB device with a VM.  I performed a complete rebuild and then upgraded from the testing-updates repo.  The virt-manager version installed is 0.8.4-1.fc13.  This bug needs to be carried forward to FE-13.

I also built this change for F13, the updated F12/F13 packages should be hitting the respective updates-testing very soon.

libvirt-0.7.1-18.fc12 has been pushed to the Fedora 12 testing repository.  If problems still persist, please make note of it in this bug report.
 If you want to test the update, you can install it with 
 su -c 'yum --enablerepo=updates-testing update libvirt'.  You can provide feedback for this update here: http://admin.fedoraproject.org/updates/libvirt-0.7.1-18.fc12

The USB libvirt launch problem for FE-13 has been corrected when updating to these packages: 

libvirt.x86_64 0:0.7.7-5.fc13                                                 
libvirt-client.x86_64 0:0.7.7-5.fc13                                          
libvirt-python.x86_64 0:0.7.7-5.fc13

libvirt-0.7.1-18.fc12 has been pushed to the Fedora 12 stable repository.  If problems still persist, please make note of it in this bug report.
