<p class="MsoNormal"><span style="font-size:11.0pt">I have configured two VMs in the same hypervisor as hot-standby mode HA. I believe they are successfully communicating with each other with heart beat packets, as we can see the primary VM kea-1 has successfully
received the “ha-heartbeat” from the standby VM kea-2 in green logs. But the red logs indicate that the ha_hooks think the HA heartbeat communications failed due to “no route”. But this is a LAN network, and there’s indeed route installed as we can see below
and we can ping the 69 ip.<o:p></o:p></span></p>

I shut the kea service on primary, then the standby won’t distribute DHCP leases even after I waited for a long time. Did I miss something here?
