Cause has been found.
rhel7 have default openvswitch.ko at  /usr/lib/modules/3.10.0-123.el7.x86_64/kernel/net/openvswitch/openvswitch.ko
The operation is as follows:
rmmod openvswitch

This is the default rhel7, centos7 kernel, which is buggy,


please upgrade to 3.10.0-123.8.1.el7.x86_64 or 3.10.0-123.9.2.el7.x86_64...


I tested those two.~


Thanks,
Alex Wang,

The OVS add  of 100 port :
ovs-vsctl  show|grep Port|wc -l
101
then  host connect lost  .


TTY show kernel info :







This is partial kernel stack which not helpful. Can you send us full kernel log to analyze it.


Thanks,
Pravin.
