I think you can now determine CPU usage in jails, even allocate cores. I think the man pages can tell you more about that, and the docs on freebsd.org. You can unmask some devices within the jail and allow only certain jails and users to access it. And finally I think you can jail a jail now, so that might be useful- especially in CPU allocation. Jails will run faster than VBox (or qemu, or VMWare), you're basically running a specific system which puts it in the same category as Xen without the Vt stuff so it will run on any hardware you choose. Thats a very good start anyway.
