So you're basically using nested virtualization for

That's a valid use case, and there are people doing it a log, and you
don't even need VMWare to do that.

In any case, even if I've never used VMWare, I suspect there is a way
to redirect the serial console of a VM to a file or a terminal, and
hence be able to see it without many problems.

As per what is going wrong, that's impossible to say without seeing the
error messages and the code. However, if you say that the problem only
manifests with your modifications, I would bet the error is somewhere
in there.
