Thanks for the suggestion, I tried that, but I didn't get very far on a single node
HCI cluster...
And I'm afraid it won't be much better on HCI in general, which is really the use
case I am most interested in.
Silently converting VMs is something rather unexpected from a hypervisor, doing it twice
my result in the same machine here only by accident.
That type of design decision needs highlighting in the documentation, because users just
won't be expecting it.
