Description of problem: With vhostuser_mode set to 'client', qemu is not able to connect to the vhostuser socket. There is path mismatch between the vhostuser socket path created by qemu and openvswitch. qemu: /var/run/openvswitch/vhu_6c1313cf-1: Failed to connect socket: No such file or directory ovs: netdev_dpdk|INFO|Socket /var/run/openvswitch/vhu6c1313cf-18 created for vhost-user port vhu6c1313cf-18 From the above output it can be noticed that, the qemu expects prefix "vhu_" while openvswitch just "vhu" and the last character ('8') in the openvswitch vhostuser socket name is missing from qemu,i.e., "vhu_6c1313cf-1" instead of "vhu_6c1313cf-18" Version-Release number of selected component (if applicable): Puddle used 2017-09-27.3 How reproducible: Steps to Reproduce: 1. 2. 3.
