[Kimchi-devel] [PATCH] [Kimchi 3/9] Virt-Viewer launcher: control/vms.py and model/vms.py changes

[dhbarboza82 at gmail.com]

From: Daniel Henrique Barboza <danielhb at linux.vnet.ibm.com>

control/vms.py:
- added a new resource called VMVirtViewerFile that
returns an URL to download the virt-viewer launcher file.
- added a new URL called 'virtviewerfile' to allow
access to the new VMVirtViewerFile resource.

model/vms.py:
- turned get_graphics() into a staticmethod to be
used outside of the vms.py module.
