What information is available on the stability and maturity of the FreeBSD KVM port? Please only share in-depth articles on why it would be stable, or why it wouldn't be based on real life experiences. "I've been running it for 2 years on my closet server without any problems!" will only get this question closed / marked as off-topic. (edit) to clarify: this is about FreeBSD being the host system, not a KVM guest.
