Description of problem:
I tried to create a fully-virtualized domain on x86_64 Xen (kernel
2.6.18-1.2747.el5xen).  After getting to the last screen and clicking on
"Finish", the "Creating Domain" dialog comes up for a few seconds, and then
disappears and drops me back at the last dialog.  On the console, I get the
following message:

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/create.py", line 388, in finish
    vm = self.connection.get_vm(guest.uuid)
  File "/usr/share/virt-manager/virtManager/connection.py", line 60, in get_vm
    return self.vms[uuid]
KeyError: 'c845d431-23e6-60b7-7186-7cd2fdfdb392'

It would seem that connection.py is trying to access an array element that isn't
there, but since my knowledge of python is so limited, I won't speculate further
than that.

Version-Release number of selected component (if applicable):
virt-manager 0.2.5-1.el5
