Can you explain why you're not using the regular memory slot mechanism? i.e. have userspace mmap(/dev/mem) and create a memslot containing that at the appropriate guest physical address? There are some issues with refcounting, but Andrea has some tricks to deal with that. -- Any sufficiently difficult bug is indistinguishable from a feature. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
