openvswitch logs for problem 1

launchpad link:

https://bugs.launchpad.net/neutron/+bug/1804842 

OSP 14

3 controllers + 3 computes + dvr

several vms in one compute with fip.

Problem 1 :

root@compute-2 heat-admin]# systemctl restart openvswitch

fip conectivity with undercloud vm is lost and no recover

conectivity with other computes is lost, but it is recovered restarting neutron openvswitch agent container

root@compute-2 heat-admin]# systemctl restart openvswitch.

Problem 2:

After kill -9 "pid ovs switch"

Sometimes the ovs switch in not restarted automatically

Same problems that in the scenario1

Red Hat Enterprise Linux Server release 7.6 (Maipo)
How reproducible:


Steps to Reproduce:
1. Install a baremetal with RHEL(theforeman)
2. Intall with jenkins: OSP 14 -- 3 controllers + 3 computes + dvr
3. Create sever vms with a Fip
4. Kill/restart openvswitch

Actual results:

Lost connectivity between fip and between vms
with kill sometimes openvswitch doesn't restart

Expected results:

No connectivity problems

Additional info:

I refer to tripleo undercloud vm:
