Summary

This patch presents an implementation of the warm migration feature for bhyve. The feature is a wrapper over the save/restore feature and sends the VM's state (memory, kernel structures, emulated devices) from a source host to a destination host over the network.

The features works only for IPv4 guests.

The usage of the feature is detailed here: Virtual Machine Migration using bhyve.

The patch was applied over https://github.com/FreeBSD-UPB/freebsd-src/commit/d26ef5c7ac830812f07a02787f25fed5d6f8609e.
