Bug 467896

Description of problem:

Installed kvm and virt-manager using the instructions found here:
http://www.techotopia.com/index.php/Installing_and_Configuring_Fedora_KVM_Virtualization

Using virt-manager in an attempt to create an XP VM, I get to the final configuration step and when I press OK, i get the following error:

Unable to complete install '<type 'exceptions.UnboundLocalError'> local variable 'verr' referenced before assignment
Traceback (most recent call last):

Notes/Observations
I would like to know if I missed a step in setup or if this is in fact a bug. I do not see any groups relating to virtualization. Looking at some instructions I used when installing an older version of virt-manager on Ubuntu, I had to  also install package 'vde2' and add myself to the groups kvm, libvirtd and vde2-net.
