SmartOS includes the Bhyve virtual machine manager, originally ported from FreeBSD. Bhyve supports most Intel and AMD processors for running hardware based virutal machines.
Bhyve offers a number of advantages over KVM, among them:
- Better tracking of, and ingegration wth, upstream FreeBSD
- Higher performance for CPU, and I/O operations (including disk and network I/O).
- Lower overhead, resulting in lower host CPU utilization while guests are idle.
Bhyve is fully supported and production ready.
