@minikube-bot ok to teset

@minikube-bot test this please

We could avoid making this a flag and set it by default for all platforms except Windows, if we think it won't work there. We'd have to move createVirtualboxHost (or a small part of it) from cluster.go into the platform-specific cluster_{darwin|windows|linux}.go files.

[dlorenc]

Actually this looks good - it looks like any recent version of windows supports this so it should be safe.
