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.
