Are you sure ?

eth0--vmbr0

eth0.1--vmbr0v1

that 2 independant bridge,
vlan tagging/untagging is done at the output/input of eth0.1, so I don't think they are vlan tags inside the bridge vmbr0v1

Ah, I understand now. But this is the proposal from yesterday? What is new here? 

AFAIK this setup will not work, because you have 'vmbr0' which listen for untagged packets, 
and 'vmbr0v2' which wants tagged packets?
