Octavia LB LXD

Hi,
Deployed and working an instance of openstack (3 node control plane, 6 node for ceph and 6 worker whit GPU) .
Now i need to configure OCTAVIA LB, but all documents deploy on node, i would like to deploy on LXD, for flexibility reasons.
My confusion is on the OVN-Chassis configuration, on the worker node, where i set a bond in LACP of 2 nic (25Gb) and on top a bridge, in ma conf i’m pointing to them:
" bridge-interface-mappings: br0:bond0
ovn-bridge-mappings: tenantvlan:br0
"
but on the LXC i’ll found only the eth nic ( in my case public, internal and overlay).
i tryed 2 confs, fist using same ovn-chassis of the worker, but the octavia manager don’t reach the amphore image, that is hold in pendig-creation
Using new dedicate app of ovn-chassis the i found the same problem.
any suggestions???
