vmbuilder default gateway not correct

[Sam Darwin]

Created a new vm on Ubuntu 14.04. The IP was 192.168.122.10 and the default gateway should have appeared as 192.168.122.1 however it was 192.168.122.11 .

# vmbuilder --version

--gw=ADDRESS Gateway (router) address in dotted form [default:
                        based on ip setting (first valid address in the
                        network)]. Ignored if ip is not specified.
