Hi Didi, Yes I opened another thread where i indicated that I've solve the issue marking BipIp HA. Thx. Eugène NG Le dim. 18 juil. 2021 à 11:17, Yedidyah Bar David <didi@redhat.com> a écrit :

Hi,
I understood we have to put hosted-engine into maintenance mode and
shutdown the VMs if we want to power off the host (otherwise it will reboot). I'm setting up a process to
- put the HestedEngine in global maintenance mode (hosted-engine
--set-maintenance --mode=global)
- shutdown the HostedEngine (hosted-engine --vm-shutdown) - PowerOff the HostedEngine (hosted-engine --vm-poweroff) - Power off the server (shutdown -P)
You might also want to check:

Everything works fine and I can start the server back up, remove the
HostedEngine from maintenance mode, and it will start automatically running. The issue is when bringing up hosted-engine: all VMs come up but one (BigIP) and I am trying to see if there is way to bring it up without having to store the engine password (using the ovirt_vm API).
The HA services on the hosts are directly responsible only for starting the engine VM.
All other VMs are handled by the engine after it's up.
Usually, the engine starts all VMs that are marked as HA.
At the moment, I am having to look for the BigIP VM and then use
credentials to bring it up: it will not come up with 'hosted-engine --vm-start'
Is this BigIP VM marked HA? If not, perhaps try to mark it so. There might have been concrete reasons you (or your team) didn't - e.g. it might rely on some other VMs to be up, or something like that.
Is there to make this specific VM start the same time as the others VM
automatically when HostedEngine starts?
There isn't, as part of the existing functionality of oVirt, other than marking it HA.
I am pretty certain I heard (on this list?) about people having more complex scripts to automate start of their env, with more complex dependencies of VMs on other VMs. You might want to search the archive. But generally speaking, I think they are doing more-or-less what you are already working on.
Good luck, -- Didi
