If you had the VMware migration extra add-on you could have hosts move
as needed so they were not tied to any host either but we could set a
startup order and specify auto, manual so that once the host started
the VMs were brought up as specified no matter what host they were
running on.  
I am running hosted-engine deployment with the Engine VM on the host.
I set highly available on, did not pin to any host, and also set the
watchdog which should reset if they go down but I'm not sure that will
start them if the host comes up and the VMs are not running.  I'll look
at the CLI first.
It would be nice if oVirt added this feature as it's really required
for large installations and is a help for any size installation, even
small ones.
