Comment 2 haidong li 2019-09-06 14:25:36 UTC 
Correct the ovs package version:
[root@dell-per730-19 ~]# rpm -qa | grep openvswitch
openvswitch-ovn-central-2.9.0-117.el7fdp.x86_64
openvswitch-selinux-extra-policy-1.0-13.el7fdp.noarch
openvswitch-ovn-common-2.9.0-117.el7fdp.x86_64
openvswitch-ovn-host-2.9.0-117.el7fdp.x86_64
openvswitch-2.9.0-117.el7fdp.x86_64
[root@dell-per730-19 ~]#
Comment 3 Numan Siddique 2019-10-24 15:51:16 UTC 
Moving back to openvswitch as it seems its an OVS issue,
We already have BZ for ovn-controller here - https://bugzilla.redhat.com/show_bug.cgi?id=1748731
Comment 6 Jianlin Shi 2019-12-05 10:03:43 UTC 
I have tried with dell-per740-12.rhts.eng.pek2.redhat.com and dell-per730-40.rhts.eng.pek2.redhat.com to reproduce the issue. the adding of logical ports are still in progress. but the cpu usage for ovs-vswitched is already very high. you can log in with root/redhat
Comment 7 Flavio Leitner 2020-02-11 17:25:05 UTC 
Apologies for the late reply, can you bring the environment back?
Comment 8 Jianlin Shi 2020-02-12 01:23:25 UTC 
the explanation is described in https://bugzilla.redhat.com/show_bug.cgi?id=1749840#c7, I think this bug can be closed
