Hi I have one question about running linux on z/VM and z/VM memory management.
My current environment (production) Total real memory = 12GB Total page volumes = +- 5GB Total memory allocation to linux servers (guests) = 7104MB (+- 7GB) Paging usage = 40 - 50% (2GB - 2.5GB) XSTORE = 2GB (just recently added after noticing paging did happen in z/VM though we have enough real memory) Main storage used by z/VM is only 5GB (meaning at any one time, 2 GB or more will be swapped off) Operating Systems: z/VM 4.4 SLES 8.1 SP4 (31-bit) I observed that by default, memory mode for linux guest is V=V. Hence, z/VM takes control of memory management. Since I have enough real memory, why z/VM still does the paging? Any way to avoid paging on z/VM. I would prefer to let linux server to have real memory (V=R). Any comments on this? And how to set it in the user direct? Any fine-tuning can be done? I also heard that V=R will not be supported in z/VM 5.1. Is it true? Thanks for your attention.
