Also related is Propolis from Oxide who worked on live migration with Bhyve https://github.com/oxidecomputer/propolis

Looks like this could really become a game changer for the FreeBSD folks using bhyve. The author often complained about this missing feature and he was also contributing to the Sylve project. Looks like he's crafting something.

so bhyve getting live migration finally means sylve might actually be usable for production clusters, been waiting on this.
