[PVE-User] VLAN between LXC containers on differents proxmox 4

[Guillaume]

Hello,

We have 2 Proxmox 4.4 servers on dedicated servers at OVH, with 2 
networks interfaces, a wan and a lan (ovh vrack solution) nic.
I tried to setup a vlan inside the vrack.

VLAN works between containers on the same proxmox (101 & 103), but isn't 
between containers on differents proxmox (101 & 102 or 103 & 102).

Here's our configuration :

* PX 1 :
vmbr0 (wan) on eth0
vmbr1 (lan) on eth1 (vlan aware) : 172.16.0.1/16

     ** LXC 101 :
     net0/eth0 on vmbr2 : 172.16.1.1/16
     net1/eth1 on vmbr2
     net2/eth1.10 on vmbr2 : 10.0.10.1/24 (vlan 10)

     ** LXC 103 :
     net0/eth0 on vmbr2 : 172.16.1.3/16
     net1/eth1 on vmbr2
     net2/eth1.10 on vmbr2 : 10.0.10.3/24 (vlan 10)

* PX 2 :
vmbr0 (wan) on eth0
vmbr1 (lan) on eth1 (vlan aware) : 172.16.0.2/16

     ** LXC 102 :
     net0/eth0 on vmbr2 : 172.16.1.2/16
     net1/eth1 on vmbr2
     net2/eth1.10 on vmbr2 : 10.0.10.2/24 (vlan 10)


What am I missing ?
I think i should have a vmbr3 bridge (using an eth1.10 interface) but 
since the web interface doesn't permit vlan configuration on the 
hypervisor (i am confortable with console), i am doubting that.

Thanks,

     Guillaume
