It is good to see support for the RM Cortex-M3 processor core and the Micrium uC/OS II real-time operating system. I wonder how hard it would be to add on new/unsupported BSDs to enable simulations of board level systems? The virtual platform / machine is a nice concept but I am wondering if there is any performance hit with using it on the bare metal machine platform in addition to the rest of the OS and related system processes?

Can't remember exact dates but around 1985/6 one of my programmers wrote an emulator for the very first ARM chip based purely on the specification of the ARM design team. Thankfully, or rather surprisingly, it worked almost perfectly first time with just one slight error. The platform for this miracle? The humble BBC Micro, okay it was a Master 128k if memory serves me correctly!

VM has been an excellent tool to shorten product development cycle. Product development team uses VM to bring up a basic Linux platform and, starts developing various applications and testing. As soon as the development is close to the last phrase, the VM will be ported to a bare metal machine for further testing and verification. It has been helping my team to get through the development cycle in a far shorter time. The challenge of this method is to port the VM to a bare metal machine. It can easily be done on x86 architecture. It becomes tricky on ARM or any other platform.
