Just looking for thoughts on where to dig to find and solve this problem. My
OpenvSwitch deployment works fine on Oracle Linux 8, but the exact same
deployment on Oracle Linux 7 has a quirk whereby after reboot, I have to stop
both switches manuall (sw1 and sx1), as shown below, and then restart both
switches, in the following order, and then all is good.
[ubuntu@o78sv1 ~]$ ifconfig sw1
