Bjoern Zeeb has provided a summary regarding the completion of the funded portion of the FreeBSD Jail Based Virtualization Project:

“I am happy to report that the funded parts of the FreeBSD Jail Based Virtualization project are completed. Some of the results have been shipping with 8.1-RELEASE while others are ready to be merged to HEAD.

Jails have been the well known operating system level virtualization technique in FreeBSD for over a decade. The import of Marko Zec’s network stack virtualization has introduced a new way for abstracting subsystems. As part of this project, the abstraction framework has been generalized. Together with Jamie Gritton’s flexible jail configuration syscalls, this will provide the infrastructure for, and will ease the virtualization of, further subsystems without much code duplication. The next subsystems to be virtualized will likely be SYSV/Posix IPC to help, for example, PostgreSQL users. This will probably be followed by the process namespace.”
