Hi Diaolin,

maybe ovs vxlan tunnel could help ? maybe less overhead than a gre tunnel

As i said to Dietmar i tested it intensively for 
adding a patch to adopt it in the PVE interface. 

Result: 

- very slow if the network is Gigabit (max 350Mbit) 
- the transport has no encryption 

I think that the better solution is to use a VLAN and 
use the entire bandwidth (if needed). 

I probed with openvpn crypted and uncrypted and i had 
a better result (more than 50% of the net bandwidth) 

This happens due to the use of bridging because if i use 
(as route) a real interface and not a vmbr the result 
are very good (OVS or OpenVPN). 

And despite i didn't write the patch... 

Sorry but if you intend to use a transport create one with 
openvpn (even in MESH mode) that works better and is encrypted
