Description of problem:

traceback creating a KVM fully virtualized x86_64 guest with LVM logical volume as disk.  Looks to be a typo 'verr' vs 'ver'?

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Launch virt-manager
2. Create a KVM x86_64 fully virtualized guest
3. Select Network tree installation method
4. Choose http://download.fedora.redhat.com/pub/fedora/linux/development/x86_64/os
5. Select a LVM logical volume as the backing store (/dev/linux/vguest1), select Next
Actual results:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/create.py", line 303, in forward
    if(self.validate(notebook.get_current_page()) != True):

Perhaps just a variable not being initialized?
