Why would we even want this many ask? + +There are potentially a lot of reasons, one obvious one to me, it allows +folks to 'kick the tires' without actually flashing up any hardware. It's +also a great environment for porting over packages, you can get a package +fully functional in the uclibc root environment inside a uml without actually +disturbing your 'real router', and then rebuild for a specific target once +it's fully tested. + +This is a first stab at a build that 'just works' and there will be more +cleanup to come. The simple directions are:- + +Configure for uml target +Configure with an ext2 root file system +build it all + +In your bin directory you will find a kernel and an ext2 root file system +when it's finished. Just run it like this:- + +bin/openwrt-uml-2.6-vmlinux ubd0=bin/openwrt-uml-2.6-ext2.img con=null ssl=null ssl0=fd:0,fd:1 con0=null,fd:1 init=/etc/preinit + +The uml will start, and eventually the serial console of the uml will be at your +console prompt. If you would like it in xterms, substitute con=xterm and con0=xterm. +No networking is configured, but, it's a starting point. The resulting file system +has just enough free space to start kicking the tires and playing in the world of +'embedded routers' along with all the resource restrictions that come with that +world. + +To configure networking and more, refer to the user mode linux documentation online. +A quick start goes along this line. install the uml-utilities packages so you have +the uml switch in and running, then add a command param to your uml start like this + +eth0=daemon,00:01:01:01:01:01,unix,/<your uml switch control socket here> + +With that in, and uml networking actually functional (can be a challenge at times), +you should be able to ifconfig the interface and talk to the host side, or, if you +bridged the uml switch to your host network, you should be able to run udhcp and be +away with networking off to the world. Again, if you are unfamiliar with uml and +uml networking, please read the docs and how-to stuff available on the net. It does +take some fiddling to get it started and working right the first time, but after that, +it opens up a whole new world of virtual machines. + + + +http://user-mode-linux.sourceforge.net/ diff
