i use opennebula to create vm,the network chose openvswitch,but when i create a new vm,i found that the port link_speed is already set only 10Mbps, so i check the support , it can use 100Mbps,but i cant modify the link_speed,does anyone can help me to modify the port link_speed value, it seems that the cmd "ovs-vsctl set interface vnet0 link_speed=100000000 " does not work ,here is the detail:
