It sounds like Mantissa is on the road that I am interested in. Specifically, I would like to see IBM incorporate the capability into z/VM to dispatch virtual machines on disparate architectures made available via co-processing capabilities, such as those currently provided for encryption, and where communication between the mainframe and the co-processor is handled using the SIGA (Signal Adapter) machine instruction. Of course, I would like to see the SIGA instruction documented in the z/Architecture Principles of Operation publication.
I can envisage a z/VM machine running z/Linux, z/OS, z/VM (2nd level), z/VSE, and thousands of copies of Windows. We can hope that the version of Windows will be more stable than Windows Vista. Moving that kind of instability into z/VM is not particularly attractive. Otherwise, on a conceptual basis, it opens up many possibilities. John P.

In Q1 2009 Mantissa will deliver a system that permits unaltered Windows operating systems to run under z/VM. Using a desktop appliance running RDC, users will be able to connect to their virtual Windows images running in the VM environment. Goodbye desktop hardware, remote maintenance, high power consumption, machine order lead time. z/VOS began with the observation that most Windows workstations do practically nothing 95% of the time and we were so intrigued with the idea of being able to actually run an intel-based operating system under IBM VM that we never looked back. VM provided a natural platform for development of this product. The product has been a bear for the development group but the thought of being able to run 3000 copies of Windows on one System z so fascinated the team that we needed very little additional incentive. Let's hope IBM can ramp up System z production." Why wait until 2016? --. .- .-. -.-- Gary Dennis Mantissa Corporation
