Why are they creating 32-bit virtual machines?  Perhaps this is a bad

This should work, in general.  It won't work on a 64-bit system that
only supports EFI boot - and the installer won't be able to report
that, unless it includes a dummy 64-bit EFI program just to do that.

We should not do in this in the second case, since it is supposed to
work.  (But a warning might be reasonable.)
