I use openswitch for it on ubuntu

apt-get install openvswitch-switch
systemctl enable openvswitch-switch
systemctl start openvswitch-switch
systemctl status openvswitch-switch

ovs-vsctl add-br external

cat << “EOT” > /etc/network/interfaces

auto external
iface external inet static
address 192.168.x.73
netmask 255.255.255.0
broadcast 192.168.x.255
gateway 192.168.x.1
dns-nameservers 192.168.x.101 192.168.x.102
mtu 9000

allow-hotplug eth0
auto eth0
iface eth0 inet manual
mtu 9000

ovs-vsctl add-port external eth0 && systemctl restart networking

And add new network to opennebula:

BRIDGE = “external”
BRIDGE_TYPE = “openvswitch”
DNS = “192.168.x.101”
GATEWAY = “192.168.x.0”
GUEST_MTU = “9000”
NETWORK_ADDRESS = “192.168.x.0”
NETWORK_MASK = “255.255.255.0”
PHYDEV = “”
SECURITY_GROUPS = “0”
TEMPLATE_ID = “2”
VN_MAD = “ovswitch”

For OVS check:

ovs-vsctl show
