Very true. You are likely correct that the OP needs more VM "def
storage" memory because the guest is doing too much paging to its paging
subsystem. Hum, perhaps we need a code phrase to distinguish VM "virtual
memory", which is guest "real memory" from guest "virtual memory"?

The question was on the VM list. I may have mistaken it for a
question about VM, not Linux ;-)

Depends on what the OP means by "virtual memory". If he
means more VM "real" (to the guest), then you're correct. But if he
needs more Linux paging memory, then a VDISK, mkswap, swapon should
help.

No. Redefining virtual memory causes a virtual
system reset. It takes an IPl after that. You can update the directory
to allow additional, but you cannot redefine the virtual storage of a
running machine without causing the reset.

Hi
I have a Linux server running now that
is in need of more VIRTUAL MEMEORY. Is there a way that I can
dynamically allocate more memory to this guest without bring it down?
Thank You,
