SLES12 with Xen installed. I am trying to create a windows server 2012r2 VM. The server has 2 NIC's and during the creation of the VM, the 1st NIC is created as br0. This NIC is the one that SLES12 will use. We need to attach the 2nd NIC to a perimeter network and therefore can not use br0. How do you, in Xen, make a bridge for the 2nd NIC?
