That looks like something different. Maybe related, but not the same problem. Note, I can create VMs with virt-manager. Unfortunately, the reporter gave the perfect explanation "it doesn't work", so I don't know what he's experiencing. I suppose he may have switched off libvirtd and then virt-manager indeed might not be able to find interfaces.
The problem I describe here happens when starting up xend. Under some not yet known circumstances the network-bridge script won't be able to determine the interfaces to juggle with because the output of ip route list is not what it expects.
