Hi, in advance sorry, i beginner. I try setting HA on oVirt. I install hosted-engine on host and after adding two hosts in web portal. When i install hosts then select DEPLOY in hosted-engine. But when i shutdown node, on which run hosted-engine, and hosted-engine is not start on other hosts automaticlly.
How long did you wait? It does take up to something like 10 minutes
normally, IIRC.
I guess that trouble in state host(he is state=EngineDown),
No, this is ok.
but not found information how to fix it. Maybe it do because i don't setting power management?
No. Power management is required for HA inside the engine, for other VMs.
For hosted-engine it's not required.
If you still have problems, please check/share
/var/log/ovirt-hosted-engine-ha/agent.log
on all 3 hosts.
