[coLinux-devel] coLinux ported to Linux

[Dan A. <da...@co...>]

Hello,

This weekend I've successfully ported coLinux to Linux. It means that a 
vmlinux can load under an unmodified Linux 2.6.3 using a kernel module 
named colinux.ko (which is the equivalent of linux.sys in Windows).

It also means that now coLinux officially joined the club that User 
Mode Linux and plex86 had started as a Linux on Linux virtualization 
solution.
