When using neutron network under xenserver, we must enable linux bridge in Dom0 as neutron will use linux bridge qbr in compute node for security group. But by default XenServer use openvswitch and disabled linux bridge. This patch is to remove this restriction. Change-Id: I0e8124ff2323810fdc46c717a750ce7e8f4aa0c6
