NetBSD Adopts NetBSD/xen for Internal Use
agent dero writes "With NetBSD 2.0, the NetBSD Foundation also released support for a new port, NetBSD/xen.
A version of NetBSD meant to run on top of the Xen virtual machine monitor. In this press release the foundation has announced that it is using the port and Xen for much of its internal development, citing security, and ease of use as main reasons for its adoption."
My understanding of Xen is that NetBSD is one of several operating systems that can run as the primary or "monitor" OS within Xen. Other operating systems (including Windows and Linux) can then be run as secondary OS'es. A research version of Windows could run as the primary / monitor OS, but it is not readily available.
I should add that I've not actually tried Xen yet, but if my understanding of Xen is correct then I'm keen to try it. I'd ideally like to have NetBSD as the primary OS, and Linux as a secondary to test the portability of server side C++ code I'm writing.
