QEMU doesn't really support doing that kind of thing, because actual Linux binaries don't execute in an environment like that. You could probably hack QEMU to mmap a file into the guest's memory before we start to run the userspace process, but there's nothing that will do what you want out of the box. thanks -- PMM
