+# In the case of SR-IOV, both physical_network and segmentation ID must be provided
+# For example to setup PVP using 2 different SR-IOV ports, you must put the appropriate physnet

+# Example of override configuration to force PVP to run on 2 SRIOV ports (phys_sriov0 and phys_sriov1)
+# using VLAN ID 2000 and 2001:
+# internal_networks:
+# left:
+# segmentation_id: 2000
+# physical_network: phys_sriov0
+# right:
+# segmentation_id: 2001
