Surely it makes more sense to simply operate the mainframe as a single high-powered server than to run a vast number of virtual servers on it?
With the amount of data Linux has to load in for the kernel (even before Apache, which has a huge memory overhead for all the multi-megabyte modules), you will be wasting a large proportion of the mainframe's memory.
Hate to say it, but wouldn't it be more effective to run NT? Although there are good reasons why Linux is not as scalable (lack of high-spec machines in the hands of Linux developers), which are being fixed - for now NT scales *far* better.
