Thank you Jarome
I'm working with LXC , but should be applied for docker as well
I can connect the container through  a virtio-user port in  VPP, and a tap 
interface in kernel
But we pay for a  vhost kthread  that is copying  data from kernel to user 
space and viceversa.
Another option is to connect with veth pair - but the performance is further 

Another issue is how VPP interface with sandbox?

Best Regards
