But we have a service restart at 21:59:31 per systemd:
$ systemctl status openvswitch-switch
● openvswitch-switch.service - Open vSwitch
Loaded: loaded (/lib/systemd/system/openvswitch-switch.service; enabled; vendor preset: enabled)
Active: active (exited) since Mon 2021-12-20 21:59:31 UTC; 16min ago
Main PID: 51024 (code=exited, status=0/SUCCESS)
Tasks: 0 (limit: 314572)

Dec 20 21:59:31 hostname systemd[1]: Starting Open vSwitch...
Dec 20 21:59:31 hostname systemd[1]: Finished Open vSwitch.
Before the restart, the ovs-vswitch.log also shows all interfaces and bridges being removed from the switch, which is why the outage lasts longer than a few seconds of switch restart. This seems to indicate to me that something greater than a service restart is happening during these Landscape system patches.
