Yes, Zones are the Solaris virtualization trick. Not a full machine, but a really beefy chroot jail concept. And yes, I'm silly enough to run Linux on SPARC, but not so silly so as to run Solaris on x86. Linux-on-SPARC has some issues, it seems, so I'm not doing much with that at the moment. I am playing a bit with zones under Solaris 10. It's useful in some ways and annoying in others. One of the features that I haven't played with but which seems useful in a production environment is that you can limit resource usage per zone -- e.g. zone_1 gets 33% of CPU #1 and 50% of CPU #2, while zone_2 gets 50% of CPU #2, and zone_3 gets 20% of CPU #1 and 100% of CPUs #3 and #4... -- Running Solaris 8, Solaris 10, Linux, OpenBSD, and OS X.
