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

2017-03-21T12:09:33.436Z|00119|dpdk|ERR|EAL: vhost-user socket unable to

Debug Log is here <http://paste.ubuntu.com/24221473/>.
For past master (2 weeks ago and with -03/march=native compiler flags)
OVS was trying to configure the socket owner as fdb/show.
DPDK Settings:
root@dpdk-compute0:/opt/build# ovs-vsctl --no-wait get Open_vSwitch .
other_config
{dpdk-alloc-mem="2048", dpdk-extra="--vhost-owner libvirt-qemu:kvm
--vhost-perm 0666", dpdk-init="true", dpdk-lcore-mask="0x1",
dpdk-socket-mem="1024,0"}

Actual socket rights after vhost create:

s--------- 1 root root 0 Mar 21 07:14 /var/run/openvswitch/vhost-user-1=
Why this happening? And one more question: can enable a debug logs for
EAL over OVS?
Thanks for help.
