Hi all, I am trying to find out why the minimum memory allocation for a domu is 4MB. I am running MiniOS and a small application that requires no more than 8 KB or RAM. Can anyone give me a comprehensive answer to this question, i am really looking to get to grips with this in detail. Is this an arbitrary decision, or is there something more meaningful at work here? Thanks Paul

hi, I''m developing my own 32-bit (no PAE) paravirtualized kernel for xen with Mini-OS as a starting point. I am currently working on process page table support (equivalent of arch/i386/mm/pgtable-xen.c) and mostly following Linux for the moment. I noticed that linux-2.6.18-xen never pins an L1 table (a pte), yet __pgd_pin() walks the page directory and gives up write access on the kernel
