.. note:: `INTF_MGMT_IP_GW` and `INTF_MGMT_CIDR` parameters are used by the VM to automatically configure virtual interface and route to allow an external access through SSH.
+.. note:: ``INTF_MGMT_MTU`` allows to specify the MTU of the management
+ interface in bytes.
+
+ If ``INTF_MGMT_MTU`` is not specified, the MTU will be configured to
+ the conservative value of 1500: this will reduce the risk to get an
+ unmanageable VM.
+
+ ``INTF_MGMT_MTU`` can also be set to the special value ``auto``: in
+ that case, the MTU will not be configured and it will keep the value
+ set by the hypervisor (default nfvbench behavior up to version
+ 5.0.3).
Using pre-created direct-physical ports on openstack, mac addresses value are only known when VM is deployed. In this case, you can pass the port name in config:
