I listened to an interesting FLOSS Weekly interview with Adam Hall and Achim Hasenmuller of VirtualBox. For someone interested in virtual machines and hardware simulation, the interview was full of interested tidbits. I think the best part was the discussion on multiprocessing in Virtualbox.
Unknown to most, IBM has one of the world’s longest records of using virtual platforms for software and firmware development and verification. This project has been ongoing since at least the days of the zSeries 900 machines, through z990, z9, and now z10. An excellent article on this virtual platform and its uses is found in the IBM Journal of Research and Development, number 1, 2009, . It is called “IBM System z10 Firmware Simulation”, by Körner et al.
