Note:
For DSR Topology it is recommended to add all interfaces on each VM, even when the VM does not require that interface or does not use a VLAN.
This is to use a standard when the topology is created from NOAM GUI.

Add all interfaces as needed. Once the other networks are added, the NICs appears.

After adding all bridges, verify and begin the VM installation.
