Bug Description

Using nova-lxd with LinuxBridge/VLAN segmentation doesn't create the VLAN tagged interface on the compute.

Seems in vif.py, function plug_bridge() checks for the 'should_create_vlan' meta tag on the network, but it is never set.
Browsing nova code, it is set only in network/manager.py, VlanManager class, which seems to be not instantied by nova-lxd.

Seems I was wrong, it is the job of the neutron agent to create the VLAN interface, but it is not notified to do it.

After some debugging, it seems that the linuxbridge agent scans only for tap devices in get_all_devices, but lxd creates veth interfaces. Maybe LXD with the LinuxBridge agent will never work?

Linuxbridge has not been a specific test target to date; however its quite possible that the switch to using os-vif in the Ocata cycle will resolve this problem.
