The nova-lxd driver has to take a slightly different approach to virtual interface wiring due to a lack of an equivalent to 'launch and pause' in LXD. For some interface types, the last mile tap device needs to be present for vif plugging to complete successfully which occurs prior to the instance being launched; This change refactors the vif module to create veth pairs directly in nova-lxd, rather than delegating this to LXD as part of a bridged network interface type. This allows vif plugging to complete prior to the instance being created in LXD. The side effect of this change is that all currently supported interface types are now configured as 'physical' interfaces in LXD profiles for instances - wiring to bridges is handled directly by the nova-lxd driver instead. This change has been validated with: ovs driver + iptables hybrid firewall driver ovs driver + openvswitch native firewall driver linuxbridge driver + iptables hybrid firewall driver The VIF wiring approach is described in detail in the VIF wiring documentation included in this change.
