Solaris "Zones" are jails, as I understand them -- the Global Zone is the native userland, other zones are jails.

Unfortunately, Sun has made Zones an intentional obfuscation -- as they not only offer some jail techniques, they also provide some hardware virtualization management interfaces on those Sun platforms that support hardware virtualization.

Sun, by the way, has had hardware virtualization capability since they acquired the SGI division of Cray that made the CS64000, re-badged by Sun as the E10000.

Hardware virtualization has been around since the mid-1980s on large scale servers. It began, I believe, with Amdahl Corporation's Multiple Domain Facility (MDF) for their System/370 compatible mainframes.
