Alternatively can we use a bridge to attach the nic interfaces(of n number of virtual machines) ? If yes then is there any specific neutron command to add a bridge and attach nics to it, this is required since as far as i know nova needs a network to spawn an instance.
if there is no specific neutron command to add bridge is there any plugin for that ( ML2 ?? )? ..
