Seems so.

ping to the gateway is an important test, because if it fails it might
mean a split-brain.
When you are asked about a 'gateway address', it's actually used only for that.
It does not need to be your gateway, but it does need to be a very
reliable thing that should always reply.

Best,

Re: [ovirt-users] Hosted Engine suddenly reboots

[Juan Pablo]

thanks for pointing me on the right direction , I have this line a couple
of minutes before the vm restart
":states::128::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(score)
Penalizing score by 1600 due to gateway status"
so looks like this is causing:
states::413::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(consume)
Host virt01-int..xx (id 1) score is significantly better than local
score, shutting down VM on this host
is this a network related issue? hosted engine and hosts are on the same
vlan, does a gateway check should be triggering a hosted engine shutdown?


thanks!
JP

You should start by checking: /var/log/ovirt-hosted-engine-ha/agent.log.
