It's work like redhat
eth0 ---vmbrx
eth0 -- eth0.10 --- vmbrxV10
eth0 --bond0 -- bond0.10 --- vmbrxV10
eth1 -|

Hi,
oh i think it's clear.
They put the vlan on top of the bond and then the bridge on top of the vlan.
without a bond they add the vlan on top of the nic and then on top of
the vlan the bridge.
Right now I'm not sure how it works under PVE. I've to recheck the code.
