It you need proxmox to use that VLAN on the bridge and then assign that
bridge to the LXC containers, then you'd need to create a bridge which
uses a VLAN configured ethX.Y/bondX.Y for the VLAN (like you did). Dunno
if "bridge_vlan_aware yes" is correct in this case.

If you simply need the LXC to be part of the VLAN then Assign the Tag.

So basically here you have 2 possible solutions:

1. make the bridge vlan aware (bridge_vlan_aware yes) and simply tag the
LXC ethernets associated with the bridge (vmbr210 with bridge_ports eth1)

2. make the bridge inside a vlan (bridge_ports eth1.10) and simply
assign that bridge to the LXC containers.

1 works for me (no on OVH though) and Michael says 2 is also working so
there must be something in your configuration or OVH vrack which
prevents it from working.
