plug(instance, vif)
plug_802qbg(instance, vif)
plug_802qbh(instance, vif)
plug_bridge(instance, vif)

Ensure that the bridge exists, and add VIF to it.

plug_hw_veb(instance, vif)
plug_ib_hostdev(instance, vif)
plug_iovisor(instance, vif)

Plug using PLUMgrid IO Visor Driver

Connect a network device to their respective Virtual Domain in PLUMgrid Platform.

plug_ivs(instance, vif)
plug_ivs_ethernet(instance, vif)
plug_ivs_hybrid(instance, vif)

Plug using hybrid strategy (same as OVS)

Create a per-VIF linux bridge, then link that bridge to the OVS integration bridge via a veth device, setting up the other end of the veth device just like a normal IVS port. Then boot the VIF on the linux bridge using standard libvirt mechanisms.

plug_macvtap(instance, vif)
plug_midonet(instance, vif)

Plug into MidoNet’s network port

Bind the vif to a MidoNet virtual port.

plug_ovs(instance, vif)
plug_ovs_bridge(instance, vif)

No manual plugging required.

plug_ovs_hybrid(instance, vif)

Plug using hybrid strategy

Create a per-VIF linux bridge, then link that bridge to the OVS integration bridge via a veth device, setting up the other end of the veth device just like a normal OVS port. Then boot the VIF on the linux bridge using standard libvirt mechanisms.

plug_tap(instance, vif)

Plug a VIF_TYPE_TAP virtual interface.

plug_vhostuser(instance, vif)
plug_vhostuser_fp(instance, vif)

Create a fp netdevice interface with a vhostuser socket

plug_vhostuser_ovs(instance, vif)

Plug a VIF_TYPE_VHOSTUSER into an ovs bridge

plug_vrouter(instance, vif)

Plug into Contrail’s network port

Bind the vif to a Contrail virtual port.

unplug(instance, vif)
unplug_802qbg(instance, vif)

unplug_bridge(instance, vif)

No manual unplugging required.

unplug_hw_veb(instance, vif)
unplug_ib_hostdev(instance, vif)
unplug_iovisor(instance, vif)

Unplug using PLUMgrid IO Visor Driver

Delete network device and to their respective connection to the Virtual Domain in PLUMgrid Platform.

unplug_ivs(instance, vif)
unplug_ivs_ethernet(instance, vif)

Unplug the VIF by deleting the port from the bridge.
