[coLinux-users] Install colinux on Linux?

[Samir K. <sam...@gm...>]

Hi all,

I have a colinux installation on windows xp. However I am thinking of moving
it to my usb hard-disk so that I am able to run my colinux either in office
or home. My only problem is that I use linux (ubuntu) at home. I was
wondering if anyone has any pointers on getting colinux to work with a linux
host system. I guess it should be possible but am a little stuck on how to
go about it.

Thanks

Samir

IMHO, you should be able to run your partitions under kvm in a similar way =
as=20
in coLinux. (but only if you own a recent processor with some virtual tech.=

inside otherwise it's like qemu : slow).

An other clue, would be linux vserver. It may be even a better solution as=

it's more like a super-chroot.
Precompiled kernels exists under Debian, so it should be easy under ubuntu.

PS: if you're skilled, you may write udev scripts to start the stuff on dev=

PPS: it may be difficult to specify your devices names in coLinux config, I=

So I guess there is no way of using co-linux on linux? I like the idea of
using vserver but can vserver run colinux images directly?

Read this "5.3. For Linux as host":
http://colinux.svn.sourceforge.net/svnroot/colinux/branches/devel/doc/building

You need to compile the module colinux.ko from source.
Kernels with REGPARM enabled dosn't work as host. Current kernel 2.6.22 
does only work, if you remove the regparm parameter from host kernel 
Makefile (and recompile the host kernel!).

Thanks. This looks promising. Will try it out.

Hi Henry,

I am having some trouble following the guide. I installed fltk-1.1.6 from
source into ~/i686-pc-linux-local. After that I ran the following commands:

====================================================================================

====================================================================================

I have attached the error I get. Do you have any ideas as to what I am doing
wrong? I am running ubuntu 7.0.4 as my host system. Thanks.

'targetkerneldir' should point to patched and configured kernel source 
for colinux guest (kernel 2.6.22 for snapshot 20070819)

Check that there exist the file
$HOME/Downloads/devel-colinux-20070819/include/linux/cooperative.h
(and mutch more kernel headers)

Replace the '~' with '$HOME', im not shure working with '~'.

After give configure a new (empty) path to targetkerneldir, you can get 
the patched kernel source by:
   "make kernel"
in source of coLinux. You can break (CTRL-C) the build after you see the 
message "Configuring Kernel 2.6.22" - if you not need the kernel build 
self. But in normal case, you need the kernel for running coLinux later. 
So, let the kernel build, before build the daemons for linux host.

Kernel build and damons build use the same config. So, it should work.

You stay in the directory where Makefile.linux exist? If yes, you not 
need the follows: COLINUX_TARGET_KERNEL_PATH, COLINUX_HOST_KERNEL_DIR, 
COLINUX_HOST_OS. This all comes from config file, you find in 
bin/user-build.cfg (created by coLinux 'configure').

This lines should be enouth:
export COLINUX_CFLAGS="-I$HOME/i686-pc-linux-local/include"
export COLINUX_LFLAGS="-L$HOME/i686-pc-linux-local/lib"
make HOSTOS=linux colinux

The daemon don't find the colinux kernel headers.

PS:
I'm not know your gcc version from your distro. The snapshot you use, 
only works with gcc 4.1.x - If your local gcc is not 4.1.x, you need to 
use the more complicated parameter '--gcc-guest-build'. Or use latest 
source, there have opened for more gcc versions.

If you can mount (either loopback or directly) you should be able to run an=
y=20
linux bin. hold on the mount point.

As a quick test, you can try to mount your colinux images, chroot inside (a=
s=20
root) and run some applications : ls, man, ...

If you can do that, running vserver shouldn't be very difficult.

Yes loop mount and chroot works also very good. For example:
   mkdir /mnt/colinux
   mount rootfs.img /mnt/colinux -o loop,rw,exec,dev
   mount --bind /proc /mnt/colinux/proc
   mount --bind /dev /mnt/colinux/proc
   chroot /mnt/colinux /bin/sh
inside chroot colinux switch to your coLinuxUser:
   cd /home/coLinuxUser
   su coLinuxUser

Without the bind mount for /dev, you need to create some basic devices 
(null, zero, tty1, tty2...)
This way I use to create and check coLinux image files.

Re: [coLinux-users] Install colinux on Linux?

[Henry N. <Hen...@Ar...>]

Samir,

host kernel 2.6.20 and later uses hard coded regparms.
You need to patch and recompile the host kernel, before you can run 
colinux there, see attachment.

Disable regparms makes the host a lidle slower.

But currently no other way is usabable to run coLinux with Linux as host 
there. The problem are the prelinked components for the module 
colinux.ko . Problems comes from coLinux build system. If all kernel 
files (for colinux.ko) would build with the host-kernel build system, 
then regparms can enable...
