Assignment

Requirements

You need to demonstrate the above steps of the presentation through a screen recording, showing how you perform live migration on VMs using the framework we provided.
(only the live migration part is required, including the process of setting up 2 guests, but not the installation process)
Naming the record video file as HW1_<your_student_id>.xxx, e.g. HW1_113062566.mov or HW1_113062566.mp4.
The length of this video should not exceed 30 minutes.
Upload the video to a cloud storage service and provide a link with viewing permission.
- This can be done using YouTube, Google Drive, Dropbox, or any other similar service.
Example:

You have to make a report of pdf format named HW1_<your_student_id>.pdf, e.g. HW1_113062566.pdf.
The report should include the following items:
- A. Provide a detailed explanation of each instruction, including the purpose of individual arguments within the commands. (5 points)
- B. Show the performance testing results by perf with and without -enable-kvm on VM; furthermore compare among them and simply explain the results (10 points)
- C. Show the performance testing results by iperf with and without virtio on VM; furthermore compare among them and explain the results (10 points)
- D. Show the performance measurements by perf and iperf during the live migration is progressing; furthermore, simply describe your observations. (10 points)
- E. What is "live migration" and why we need it. (10 points)
- F. QEMU has a "fault tolerance" feature called COLO. We don’t ask you to utilize this feature in this assignment, but some questions you may answer :
  - What is fault-tolerance in virtualization technology and why we require it? (7.5 points)
  - What are the relationships between live migration and fault-tolerance? (7.5 points)

Submit both the demo video link and the report to eeclass.

The deadline is set for October 26, 2025 23:59. Late submission is not allowed.

If you have any question, feel free to asking through eeclass or email.
