Dear All,

I need setup vlan on interface enp6s0. Please give help me resolve this case.

Thanks all.

hello, in that case you have to Add new network, select 802.1q, Select Automatic or Manual VLAN ID (in this example I use ID 101), as Physical device write enp6s0 and add address range. thats all. Opennebula on background when you deploy first VM to that network, creates new interface enp6s0.101, which is tagged vlan 101 and also creates new bridge with that interface. VM interface will be added to that newly created bridge.

update: if your switch supports dynamic vlans, you can add custom ip link params to enable gvrp protocol. In that case vlan will be automatically created on switch. So you can adding new networks just via sunstone.

IP_LINK_CONF gvrp=on
