I think its fair to say that a) Almost none of the linux developer community has a 390 b) We all know about the issue c) IBM haven't as far as I know attacked it yet On the positive side its a solved problem in the x86 virtualisation space where Xen uses a driver to pull memory out of virtual machines according to overall system requirements (in essence the driver allocates memory according to load and gives it back to the VM then when the kernel wants more allocates from the VM and gives back to the kernel) Xen does this without any core kernel vm changes ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
