Joyent is running on Illumos which is based on OpenSolaris which
is open source.

Illumos can also run KVM and bhyve and zones all at the same time,
its rather nice in they have done some things that support this,
some of which I am working with Joyent on bringing to FreeBSD
(mainly the ability to have more than one type II hypevisor running.)

But first there is some cruft cleaning being done for both
FreeBSD and Illumos, removal of constant VM_MAXCPU so you
can run bhyve guests with as many threads as your host has.
