Hi,
So I have two hypervisors HV1 and HV2
I have two VMs in the same subnet one on each hypervisor HV1-VM1 and HV2-VM1
I have a distributed gateway router configured and scheduled to both
hypervisors
Initially scheduled on HV2.
When I set the network interface on HV2 to down, I expected the gateway
to move
to HV1, but it does not.
I'm suspecting that it is because HA not supported if the gateway is
scheduled on
compute node hypervisors, as opposed to "controller" hypervisors, is
this true?
details of my config:
