Even if linux on s/390 bare metal could do the same performance wise as it
on VM, linux still wouldn't be able to partition the system in any
meaningfull way, which to me is the whole point of a mainframe.

I haven't heard of any projects to add such partitioning to linux, except
that new versions of VMWare can be used to add some partitioning.
