@resistor @jmc #SmartOS (an illumos distribution) powers the #mnx.io cloud and bhyve is used in several (thousands) of instances running production workloads. So I think bhyve is already production-ready in #illumos, also #illumos can do double-hulled virtualization for added security (this means bhyve runs inside a zone, so if an attacker escapes from the hypervisor he/she just lands in a somewhat useless zone), something like that in #FreeBSD was not working out of the box, the last time I checked, also networking in jails, is not as easy as crossbow in #illumos.
