Description Major Hayden 🤠 2014-03-05 04:29:22 UTC
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.

Just made the edits from Cole's commit on my server and that fixed the bug. I'm able to view VM consoles and details without issue.
