<div>Hello everyone, I have configured a nova-compute-lxd node in our openstack environment. We are currently running Openstack Mitaka (Not Devstack) with neutron. I am able to provision instances however they have no network connectivity. When using a
regular provider network and not VxLAN networks, if I add the provider network (em2 in my case) to the bridge group manually it will function properly. So it appears that the interface is not added to the bridge during the provisioning process. </div>

<div>My neutron config on the host has </div>

<div>physical_interface_mappings = public:em2</div>

<div>This is for VxLAN support.</div>

<div>Any idea on what I might be missing? Does the LXC implementation support VxLAN? When I provision an instance with VxLAN the vxnet—XX interfaces do not seem to get created either. </div>
<div><br>
</div>
<div>This is what brctl looks like after provisioning a VxLAN instance. </div>
