Concepts and Applications
Welcome students! ... to
the Virtual Machines course, edition Spring 2014.
I will keep updating this page regularly. If you have
questions related to this course feel free to email me.
Here is some basic information:
technology from VMware, IBM, Xen, Microsoft, and
others is an indication of the importance of this technology,
this era where almost everything is in the cloud. Virtualization became
world's hottest trend in recent years. Have you ever wondered how you
multiple operating systems, at the same time, on a single physical
system and share the underlying
hardware resources? How does your operating system see a hardware that
from the actual hardware, and why we need to do so? What is a virtual
machine is the answer to all that and much more. In this course we will
the design and implementation of virtual machines, virtual machine
(aka hypervisors), as well other recent trends in virtualization. We
virtual machines across the disciplines that use them: operating
programming languages, and computer architecture.

Suggested projects (can be done in groups up to 2 students)
an address stream, design a profile that scans this stream and
generates the following: CFG, block profile, edge profile, branch
- Given specs of dynamic basic blocks (start address,
size in bytes, end address, number of instructions) as well as the
stream of their execution and the code cache size, design a code cache
simulator with replacement policy to reduce code cache miss.
an assembly (in some ISA) file, emulate it on the x86 machine,
generating the exact output as if the initial code is running on the
- Use PIN to generate start and end addresses of
dynamic blocks and the frequency of each one dynamically. Then form
superblocks (using profiling all blocks and a heuristic and compare the
- Make a translator from ISA1 (e.g. MIPS R3000) to ISA2 (e.g. IA-32)
- Given an address stream, decide on code rearrangement to increase locality.
- A project of your choice (but need to discuss it with me first).
All the reports below are to be emailed as pdf to the instructor and grader as well as hardcopy in class.
The subject of the email: "VM project: phase x" (where x is the phase number)
Phase 1: Problem definition and challenges report (Due April 2nd, 2014) [Grade 5%]
- What is the problem you are trying to solve?
- Why do you think this problem is important (you can answer this by giving scenarios of usage if you want)?
- What are the challenges you see in this problem?
Phase 2: Design report (Due April 16th, 2014) [Grade 10%]
- Given the challenges you mentioned in your previous report, how are you going to solve them?
- Why do you think your solution is good?
Phase 3: Project submission (Due April 30th, 2014) [Grade 15%]
- A report that contains the above 2 reports
- A user manual that states how to compiler and run your program and what is the ourput
- The source code
- Put all the above in a one zip file: lastname.firstname.zip
