[20060729] sysjail: a userland virtualisation system using systrace
Found via the #NetBSD community blog, I'm blogging this so I'll find it later when I'm looking for it in my tag list: ``sysjail is a userland virtualisation system for operating systems supporting the systrace library. It runs on OpenBSD and NetBSD. The first generation of sysjail is as close to a drop-in replacement for FreeBSD's jail subsystem as permitted. As with a jail, processes within a sysjail are disallowed resources belonging to the system proper, known as the "host" system, or other sysjail instances. While sysjail currently behaves as an OpenBSD implementation of jail, it has the potential to provide significant auditing, profiling and debugging tools allowing full auditing of intercepted system calls, run-time modification and extension of policies, etc. The sysjail sources are released mainly under the BSD 3-part license (see sources).''

See the sysjail homepage for more. If anyone tries this and has some experiences to share, please send mail to some NetBSD list (and CC: me :).

[20041207] Server virtualisation with NetBSD
Answering yet another cry for Jails, Thor Lancelot Simons has made an interesting statement that Xen can be used in a much more decent way for sandboxing and virtualizing NetBSD, creating server housing boxes and the like, with no need for extra hacks in existing parts of the operating system, but using the Xen virtual machine as an unterlying system to realize this. And of course use NetBSD/Xen" as operating system.
