[ovirt-users] Changing the engine HA ping address?

[Chris Adams]

I have an up-to-date hosted-engine 3.5.1 setup (CentOS 7 for the nodes,
CentOS 6 for the engine), and the engine keeps jumping between the two
nodes running the hosted-engine HA (sometimes after just 10-20 minutes,
sometimes after a day or two).  I figured out that it is failing on
pinging the gateway sometimes.

The gateway IP is a layer-3 switch, and I think sometimes it just is not
responding to ICMP echo request in a timely fashion (traffic is routing
just fine though).  How is the HA ping implemented?  How many requests
does it send (and how many responses are required to be considered
"good")?

If I can't tweak the sensitivity of the ping, I'd like to ping a
different IP (on a HA load balancer setup).  The oVirt HA config refers
to it as "gateway" though; is it really used as a gateway in any case,
or is that just the recommended IP?

Can I just edit /etc/ovirt-hosted-engine/hosted-engine.conf on the two
nodes and restart the ovirt-ha-broker service?
