Hi Steven, Thanks for your help. I am using vhost-user client (VPP in container) and vhost-user server (VPP in host). I thought it should work.
create vhost socket /var/run/vpp/sock3.sock server (On host) create vhost socket /var/run/usvhost1 (On container) Can you please point me to a document which shows how to create VPP virtio_user interfaces or static configuration in /etc/vpp/startup.conf? I have used following declarations in /etc/vpp/startup.conf # vdev virtio_user0,path=/var/run/vpp/sock3.sock,mac=52:54:00:00:04:01 # vdev virtio_user1,path=/var/run/vpp/sock4.sock,mac=52:54:00:00:04:02 but it doesn't work.
