    XenAPI: Create linux bridge in dest host during live migration
    
    We found VM can live migrate successfully with XenServer hypervisor,
    but after migrating to dest host, we cannot ping the VM's floating
    or fixed IP any more. The problem is, during live migration, we only
    create the network in dest host which the VM's VIF connect to, but we
    don't establish the linux bridge and the corresponding veth pair to
    integration bridge br-int.

Title:
  VM cannot get fixed IP after live migration successfully

Bug description:
  I'm using XenServer 7.0 XenAPI driver + upstream

  I found VM can live migration successfully with XenServer hypervisor, but after migrating to destination host, we cannot ping the VM's floatig or fix IP anymore. 
  After using our XenCenter to login to the VM, I found the VM even doesn't have fixed IP via DHCP. So checking the coded and found out although live migration is done successfully, but during live migration, the driver  only create the network in destination host for the VM's VIF to connect, but lack of linux bridge and the corresponding connection to ovs bridge br-int.
