--000000000000e24b8e05f9250ec9 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable A lot of years ago I found this interesting project : http://www.colinux.org/ I've been always fascinated by it : *Cooperative Linux* is the first working *free* and *open source* method for optimally running Linux on Microsoft Windows natively. More generally, *Cooperative Linux* (short-named coLinux) is a port of the Linux kernel <http://www.kernel.org>; that allows it to run cooperatively alongside another operating system on a single machine. For instance, it allows one to *freely* run Linux on Windows 2000/XP/Vista/7, *without* using a commercial PC virtualization software such as VMware <http://www.vmware.com= >, in a way which is much more optimal than using any general purpose PC virtualization software. How could it be hard to create something like this ? I mean,a cooperative kernel between the linux kernel and the freebsd kernel. A sort of Linux kernel that will run alongside the FreeBSD processes. Maybe even integrated within the (centos) linux emulation layer that already exists under FreeBSD. In the end,what's missing on the LEL is a kernel.
