Description of problem: After upgrading to virt-manager/virt-manager-common 1.0.0-3.fc20, I can't view the VM console or VM details in virt-manager. I receive the following error on the screen: Error launching details: 'NoneType' object has no attribute 'cpus' Version-Release number of selected component (if applicable): Working version: 0.10.0-5.git1ffcc0cc.fc20 Non-working version: 1.0.0-3.fc20 How reproducible: I build Xen HVM VM's in virt-manager 0.10.0-5 and was able to view/edit details and view the VM console without issues. After upgrading to virt-manager 1.0.0-3, I could no longer view/edit details or view the VM console. I was given the "Error launching details: 'NoneType' object has no attribute 'cpus'" error in virt-manager. Steps to Reproduce: 1. Build a Xen VM in virt-manager 1.0.0-3 2. When the installation begins, you'll see the previously mentioned error 3. The VM will boot successfully but you can't view console/details in virt-manager Actual results: Error -> 'NoneType' object has no attribute 'cpus' Expected results: I'd expect to see the standard virt-manager window containing the VM console and details. Additional info: This affects PV and HVM Xen VM's from what I've seen. Downgrading to virt-manager 0.10.0-5 fixes all the problems. Restarting libvirtd had no effect.
