[virt-tools-list] [PATCH 1/4] IPv6 support v2: update gui python and ui



The purpose of this update is:

1. replace use of IPy with ipaddr since ipaddr has needed
functionality and IPy does not.
2. Update the glade-3 ui (vmm-host.ui) to provide
for IPv6 as well as IPv4.  If either IPv4 or IPv6
is not defined, its respective frame is hidden.
3. The DNS Domain Name is added to the basic frame.
4. IPv4 forwarding is moved to the basic frame and ipv6
forwarding is added.
5. If an IPv4 address is not defined then the IPv4
is set to Isolated network, internal rout only.
6. IPv6 network has three values for Forwarding:
Isolated network, Isolated network with internal forwarding,
and Routed network.
7. Add network definitions to tests/testdriver.xml which
include IPv6 and other new parameters now being handled.

This patch includes the fix for getting a KeyError exception
when deleting a network definition.

In this update, createnet.py has been changed to use
ipaddr but it still only handles IPv4 network creation.
