[ovs-discuss] ovs-vsctl adding dpdk ports hangs

[Shivaram Mysore]

One more data point:

I *CNTRL-C* the command ovs-vsctl add-port

^C2017-03-24T05:25:30Z|00002|fatal_signal|WARN|terminating with signal 2
(Interrupt)


# *ovs-vsctl show*
0a0e3abd-c1de-40fd-bc14-9a8edb89982d
    Bridge "ovs-br0"
        Port "ovs-br0"
            Interface "ovs-br0"
                type: internal
        Port "dpdk-p0"
            Interface "dpdk-p0"
                type: dpdk
                options: {dpdk-devargs="0000:82:00.0"}

Looks like port is created.

I see add-port and del-port is very very slow - basically hangs and I have
to CNTRL-C.  Nothing in the logs.  I am not sure what is causing this.  I
never had any issues without DPDK.

Thanks
