Can you shutdown the vms just for the upgrade process?
In order to run the playbooks you would also need the parameters that they use - some are set on the engine side
Why can't you upgrade the host from the engine admin portal?
Because when you upgrade a host you put it into maintenance before.
And this implies no VMs in execution on it.
But if you are in a single host composed environment you cannot....

we are talking about chicken-egg problem.....
You say to drive a command form the engine that is a VM that runs inside the host, but ask to shutdown VMs running on host before...
This is a self hosted engine composed by only one single host.
Normally I would use the procedure from the engine web admin gui, one host at a time, but with single host it is not possible.....
