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.

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.
