Auto-starting VMS in a all-in-one / confusion.
I've been digging thru mailing lists and blogs and I'm a bit confused about how you have VMs auto-start after a reboot in a ovirt system that is setup as all-in-one.
From what I can gather this can be achieved via some startup scripts (or a rc.local foo).
But there is no setting inside the WebUI that can be set to achieve this? Or have I missed something.

You have not missed anything. As of right now there is nothing in the WebUI to configure this. It can only be done by startup scripts. Me, I run my script on my hosted-engine VM. -derek -- Derek Atkins 617-623-3745 derek@ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

we recently removed the limitation of “cannot enable HA on a single host” for High Performance VM profile in 4.2 [1]. It can work for this case too, perhaps It may need [2] too which would mean it currently work for High Performance VMs only - if it works at all.

HA on a single host is kind of a bad labeling of options IMHO. HA-SPOF (that makes me giggle a little). But maybe another option simply as "Start VM when engine is ready" and an ever more awesome setting would be the ability to # the VMs and how they start. This is very home use case stuff tho and I get if it's out of the scope of 4.2 usages. But it would be nice, since I run a beefy machine with 20+ VMs on it at home. And being able to say start my puppet server before everything else, then start the DBs before the WEB server, etc, etc. I know this is feature request, I'll grab all the source tonight and see if I can make a diff.

I don't understand where to set the 2. Enable "autostart" described in the referred bugzilla, that is marked as 'closed current release", so that I can test this feature in case of single hosted engine host environment Thanks, Gianluca
