Openwrt inside a user mode linux. 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 ext4 root file system
|
|
build it all
|
|
|
|
In your bin directory you will find a kernel and an ext4 root file system
|
|
when it's finished. Just run it like this:-
|
|
|
|
bin/uml/openwrt-uml-vmlinux ubd0=bin/uml/openwrt-uml-ext4.img con=null ssl=null ssl0=fd:0,fd:1 con0=null,fd:2
|
|
|
|
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.
