In Engine VM System settings, advanced parameters, I currently have this
config:
https://drive.google.com/file/d/0BwoPbcrMv8mvQ29ickF2cWlMNUE/view?usp=sharing

I have to check if it is only one of the 2 parameters generating problems
or only one.

Nevertheless, if I try to change Custom Emulated Machine I then get:

"
Error while executing action:

HostedEngine:

    There was an attempt to change Hosted Engine VM values that are locked.
"

and the same if I try to change Custom CPU Type...

On the Hypervisors (actually ESXi VMs) I get this when running the command:
