Lets take as one example Oracle RAC. Oracle uses a VMWare environment to
teach their RAC classes. I find that horrifying as I don't think people
learn real-world skills in unreal environments. But obviously RAC is
stable running on VMWare. That does not mean it will scale and that does
not mean it is easy to support when configured creatively which is the
point of most VM environments.
