Lab 4: Live Migration in a Group
Dear VM Nomads
- After migrate your first VM, you now need to move to a place with rich resource
- Migrating many docker images and doing it lively until your system halts
- Analysis why it halts and understand the idea of resource bottleneck
Goal for Lab 4
- Objectives:
- Understanding the basic techniques for VM migration
- Migrate containers to test your migration skill
- Understanding the concept of checkpoint and restore
- Successfully migrate multiple images either one by one or in a batch Writing a decent report
To Start
- Learn to do live migration in docker
- Using Checkpoint and Restore (CRIU) tool in docker to do this job
- https://criu.org/Live_migration is your source to check
- Ask one of our friend/roommate and migrate your Golang job (with your ID or name) to his/her place
- Measure the duration of migration and collect all other runtime statistics
- New stuff: Write a script to move docker image automatically
Hints and Remarks
- CRIU tool is your best way to make it happen or you may implement your own code to do it
- More information can be found in docker-engine mail list and GitHub issues
- Either you steam your docker image or repeat your previous experiment in a fast loop
- Increase the number of concurrency and see when your system freezes
- In your report, you can show us when your system fails, how it fails and why
Bonus: if you find a way to fix the bottleneck and show us how it is being fixed based on reasons you found, you will get bonus points
