First, thanks for your informative reply. One argument against linux on z/VM I have heard a lot is that memory on a mainframe is expensive compared to memory for vmWare ESX-hosts. Do you know any rough estimates for how much physical memory that is needed for each linux host on z/VM that is running WAS? I know z/VM implements various techniques to reduce overall physical memory requirements among a set of hosts, but how effective is it?
