class LibvirtBridgeDriver(get_connection)

Bases: nova.virt.libvirt.vif.LibvirtGenericVIFDriver

Retained in Grizzly for compatibility with Quantum drivers which do not yet report ‘vif_type’ port binding. Will be deprecated in Havana, and removed in Ixxxx.

class LibvirtGenericVIFDriver(get_connection)

Bases: nova.virt.libvirt.vif.LibvirtBaseVIFDriver

Generic VIF driver for libvirt networking.

get_config_802qbh(instance, network, mapping, image_meta, inst_type)

get_config_bridge(instance, network, mapping, image_meta, inst_type)

Get VIF configurations for bridge type.

get_veth_pair_names(iface_id)

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_ovs(instance, vif)

plug_ovs_bridge(instance, vif)

No manual plugging required.

plug_ovs_ethernet(instance, vif)

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.

unplug(instance, vif)

unplug_802qbg(instance, vif)

unplug_802qbh(instance, vif)

unplug_bridge(instance, vif)

No manual unplugging required.

unplug_ovs(instance, vif)

unplug_ovs_bridge(instance, vif)

No manual unplugging required.

unplug_ovs_ethernet(instance, vif)

Unplug the VIF by deleting the port from the bridge.

unplug_ovs_hybrid(instance, vif)

UnPlug using hybrid strategy

Unhook port from OVS, unhook port from bridge, delete bridge, and delete both veth devices.
