Hi Anda,

physnet is used for physical NIC mapping on provider networks.

"The physical_device_mappings parameter is not limited to be a 1-1 mapping
between physical networks and NICs. This enables you to map the same
physical network to more than one NIC. For example, if physnet2 is
connected to eth3 and eth4, then physnet2:eth3,physnet2:eth4 is a valid
option."
