In late November the FreeBSD team released FreeBSD 8.0.

It finally introduces the experimental support for the Xen domU. This means that FreeBSD 8.0 can run as a (32bit only) Xen guest operating system.

FreeBDS 8.0 also introduce a new experimental feature called “vimage” as part of its OS virtualization technology “jail”, which partitions the network stack.

The vimage jail has its own loopback interface and a separated network stack that includes routing tables. The vimage network interfaces can be moved between different vimage jails and outside of them.
