Are you sure that you gave a fast read to this page ? --->
https://l4re.org/download/snapshots/

They say :

You are free to use any Linux distribution you like, or even BSDs or any of
its derivatives. But then you should know the game. Especially tool
versions should be recent, as installed on the listed distributions below.

We are confident that the snapshot works on the following distributions:

   - Debian 11 or later
   - Ubuntu 22.04 or later

so,it seems that they found a way to use an updated linux version.
Unfortunately they don't talk about FreeBSD. It deserves more
research,because this is what I'm interested in.

This is pure speculation because I don't have time to dig deeper into 
L4Linux but I think the whole solution will be worse than Xen. When 
Linux is really run as a process this means:


a) It's likely that it's an adopted version of the linux kernel so it's 
likely also old


b) A process is a strictly defined thing with a clearly defined API that 
is actually designed to do very different things, the things an OS 
Kernel does might fit very bad into that meaning that a lot of the 
behaviour might have to use workaround and might be quite imperformant. 
For example the linux kernel is multithreaded and different kernel 
threads can talk to each other quite easily, can they do the same on L4? 
Might be difficult.




Thanks for your 
invitation to read. Yes,I'm very interested in all the virtualization 
stuff all around,but I'm not sure that reading a complicated book will 
help me. 


I'm actually sure about that and the answer is no. But "Modern Operating 
Systems" is no complicated book, it's a very easy to read introduction 
for beginners, usually it's read by undergraduate students that have 
never programmed before.


My training at the college has been totally different,I'm a 
psychologist. Do you think that one can be able to learn by himself how 
an operating system works by reading and studying a book found on the 
Internet,without the support of a teacher ? 


Yes, given enough motivation and work ethic. I've never heard even one 
university course on linux kernel programming, my university degree was 
mostly about math


Do you think that we can remove 
colleges from the face of the earth ?


No, because lots of people don't have enough motivation, work ethic or 
structure, actually I think the benefit of colleges / universities is 
not really the subject but teaching people the skills to actually 
acquire knowledge themselves and abstract thinking.

Thanks. That's exactly what I was looking for. Actually we are trying to
boot FreeBSD with xen on our arm 32 Chromebook. But if it fails we could
try L4Linux. Yes,they say that's similar to xen,but with some important
differences that I haven't read and understood yet. Thanks for your

Do you think that one can be able to learn by himself how an operating
system works by reading and studying a book found on the Internet,with the

I looked at this,

L4 is a family of Microkernels: 
https://en.wikipedia.org/wiki/L4_microkernel_family


L4Re is a project to let other operating system kernels run as processes 
on top of a L4 Kernel. But they are still monolithic kernels even when 
you run them on top of another kernel. Actually all this is similar to Xen.


Since you are interested in those things I would really recommend

Neither FreeBSD nor Linux has a microkernel. From all your
questions I
think it would be helpful to read up on some Operating System
Theory
before you go on. I can recommend "Operating Systems - Three Easy
Pieces"

(https://techiefood4u.files.wordpress.com/2020/02/operating_systems_three_easy_pieces.pdf
 

)

It's almost as good as the Tanenbaum Classic, but free.

Ok but then what it means what I read below (taken from wikipedia) :

L4Linux also allows setting up a virtualized
 environment vaguely similar
to Xen  or Kernel-bas

ed Virtual Machine
 (KVM), but a
few significant differences exist between the intent of Xen and L4Linux.

Neither FreeBSD nor Linux has a microkernel. From all your questions I 
think it would be helpful to read up on some Operating System Theory 
before you go on. I can recommend "Operating Systems - Three Easy 
Pieces" 
(https://techiefood4u.files.wordpress.com/2020/02/operating_systems_three_easy_pieces.pdf 
)


It's almost as good as the Tanenbaum Classic, but free.

Thats a micro-kernel, sort of like GNU Hurd.

Re: from CoLinux to MoreLinux :D

2023-12-08 Thread Mario Marietto 
Infact from Wikipedia I can read :

L4Linux also allows setting up a virtualized
 environment vaguely similar
to Xen  or Kernel-based Virtual Machine
 (KVM), but a
few significant differences exist between the intent of Xen and L4Linux.


With Redox can I do the same ?

What is this ?

https://l4re.org/download/snapshots/pre-built-images/arm-v7/

It seems to me that it does what Colinux did a lot of time ago,but it works
even on more cpu architectures. Am I wrong ? With l4linux I can run
multiple linux distros using the same kernel. I'm very curious to try it on
my ARM machine,since there is even a version for arm 32 and arm 64 bit. It
sounds interesting.

Hello.

maybe someone of you know the old project called "coLinux" :


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 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, in a way which
is much more optimal than using any general purpose PC
virtualization software. In its current condition, it allows us to
run the KNOPPIX Japanese Edition on Windows.


CoLinux is very old and not maintained for a lot of time and I'm not 
interested in resurrecting it (and I don't have the competences to do 
it),BUT I'm interested to gather some information about a similar 
project that I have in mind. What about if,instead of having a Linux 
kernel which can run Windows cooperatively,we have a Linux kernel that 
can run more Linux distributions (maybe only 2 as a starting point,as 
CoLinux already does) at the same time,without using virtualization 
software ? 

Check out: User Mode Linux

Is the technology behind Colinux the same that's under the 
lxc or docker containers 

No

or the WSL2 subsystem ? 

No


What are the differences ?


With LXC you still have just one Linux kernels, but for processes it 
"feels" like they have their own kernel "alone" but actually they are 
just isolated from the other processes. The kernel got better in 
providing processes own seperated "environments".


WSL is bascially using a VM



I don't use WSL2,I don't use Windows so much. I like Linux and FreeBSD. 
So,an even nicer idea is to create a coLinux variant that allows the 
Linux kernel to cooperate with FreeBSD. This is even nicer than making a 
cooperation between 2 Linuxes.


I don't really see why (except for engineering curiosity maybe) but 
google, maybe there is something like this, you might also like Debian 
GNU k FreeBSD
