[virt-tools-list] --show-* options are broken

[Leonardo Augusto Guimarães Garcia]

Hi Cole,

Just FYI, commit 76887c9a3280da32d44d4276135a78d21dd12fe8 broke the 
--show-* functionality.

Traceback (most recent call last):
   File "/home/laggarcia/src/git/virt-manager/virtManager/engine.py", 
line 624, in _show_vm_helper
     details = self._get_details_dialog(uri, uuid)
   File "/home/laggarcia/src/git/virt-manager/virtManager/engine.py", 
line 602, in _get_details_dialog
     obj = vmmDetails(con.get_vm(uuid))
   File 
"/home/laggarcia/src/git/virt-manager/virtManager/connection.py", line 
625, in get_vm
     return self.vms[uuid]
KeyError: '927c2b5f-ae3a-4f5e-aaeb-4d7fb3846dce'

Basically connections vms are not populated yet when trying to open the 
dialog.

I am investigating the issue.

Best regards,

Leonardo Garcia
