Re: Rolled my own Simulator/Emulator

Hmm, you have a linux in an ARM environment inside Qemu inside an Ubuntu in VMWare Fusion on a Mac?

It is a very strange setup, but it could run on my windows with VMWare Workstation, too

Is it possible for you to share your vmware image as a kind of quickstart?
