(cough) As many customers who have talked to me can attest, no, they are not always right. :-) They can have good intentions and excellent ideas, but the technology is sometimes simply not there to support those ideas. And, occasionally, it's just a Bad Idea. In this case, it is technically possible to run Windows servers on System z today using Bochs, the Linux open source IA-32 emulator, but it qualifies as a Bad Idea due to the performance. It's certainly interesting from an academic perspective, but it doesn't meet the needs of business. So we await Mantissa's offering with bated breath - to see if we can get the utility of x86 with the management characteristics and scalability of System z, at a cost people can afford. Even the Xen solutions do not do cross-architecture virtualization. If you run Xen on x86, you get x86. If you run it on Power, you get Power. If it were to run on System z, you would get z/Architecture. I keep waiting for an operating system written in Java with a byte-code-interpreting CPU!
