  2. Questions • What is the difference between virtualization and secure multiplexing? • What do Exokernel and Disco have in common? • What do Exokernel and Xen have in common? • Do Xen or Disco do secure multiplexing? • Does Exokernel create virtual machines? • Is Exokernel a micro-kernel? • What abstractions does it support? CS533 - Concepts of Operating Systems

  3. Questions • What is a "process" in the Exokernel? • Does the Exokernel "paravirtualize" privileged instructions? • How are address translations and physical memory managed in the Exokernel? • How does Exokernel’s visible revocation relate to scheduler activations? • How does it differ from Xen and Disco in this respect? • How does PCT relate to LRPC? • What is the difference between synchronous and asynchronous PCT?

  4. Questions • How does Exokernel use hardware support to improve performance? • How are "software caches" used to improve performance? • How is "downloaded code" used to improve performance? • How does this relate to Sandboxing? • How does this relate to SPIN? • How does this relate to Specialization? • What do hardware support, software caches and downloaded code have in common?
