I hope you will keep this configuration in your design space as you move 
As you can see it is likely to be a popular one. At a previous employer, 
everybody in our development group had a single (powerful) machine 
running VMware vSphere, with a hosted vCenter, to use as a development 
VM testbed.

It's likely to be popular for people with few resources who want to run 
in a fully supported configuration.

HA is great, but not every environment has the resources/requirement to 
support it. oVirt has a lot to offer even a leaner environment and I 
hope those environments continue to get attention as the product 
matures. For example, I hope there is a reasonable story around upgrades 
to future releases for single-node hosted configurations.

What is the recipe for a clean startup after shutdown?
Can we do 'hosted-engine --vm-start' while the system is in Global 
Maintenance mode?
