Hello. Meta. OVS ver: 2.7.90, today master (stp tests skipped) Compiler: GCC 5.3.1, default flags DPDK: 16.11.1 (from Ubuntu Cloud Archive: Ocata) Env: Ubuntu 16.04.1 up-to-date. Kernel: 4.8.0-41-generic Problem. When I adds a vhost-interface into bridge OVS specifies incorrect rights for the socket: root@dpdk-compute0:/opt/build# ovs-vsctl add-port br-ex vhost-user-1 -- set Interface vhost-user-1 type=dpdkvhostuser 2017-03-21T12:09:33.436Z|00115|dpdk|INFO|VHOST_CONFIG: vhost-user server: socket created, fd: 46 2017-03-21T12:09:33.436Z|00116|dpdk|INFO|VHOST_CONFIG: bind to /var/run/openvswitch/vhost-user-1 2017-03-21T12:09:33.436Z|00117|dpdk|INFO|EAL: Socket /var/run/openvswitch/vhost-user-1 changed permissions to ���� 2017-03-21T12:09:33.436Z|00118|dpdk|ERR|EAL: user �ƿ not found, aborting. 2017-03-21T12:09:33.436Z|00119|dpdk|ERR|EAL: vhost-user socket unable to get specified user/group: �ƿ This worked better for me.

For past master (2 weeks ago and with -03/march=native compiler flags) OVS was trying to configure the socket owner as fdb/show.
