Description Alexey 2018-10-31 15:26:10 UTC 
Politehnica University of Bucharest developed a snapshot system for bhyve. It would be nice to integrate it into existing code.

This functionality makes great use of CBSD:

This project has been superseded by the bhyve migration project. The goal is to provide warm & live migration in addition to the save & restore features. It's still under active development and not all of the bug fixes applied to the migration repo have been applied to save_restore repo. It's probably best to wait for the code and review process to be completed.

I will take it as I'm working with the students and I'm very interested on this project too.

(In reply to mgrooms from comment #1)
Live migration is based on this work, but I'm not sure about “superseded”.
These are different things and in the virtualization world none of these things replace another
