[coLinux-users] coLinux inside VirtualBox on Linux ?

[Frédéric L. W. M. <lis...@pe...>]

Is that combination supposed to run ?

I ask because I want to do some tests with coLinux, but not like 
on Windows, where I use the stable coLinux snapshots with my 
Linux partition and don't run into a problem for a long time.

I customized the 2.6.22.8 kernel, removing options I don't need, 
adding others (not drivers and such), am also willing to try out 
the 2.6.25 patches, but don't want get lots of BSOD's if things 
go wrong.

What if I run coLinux inside VirtualBox's VM, that has Windows 
XP SP3 ? Is it supposed to work ? But if it does, can it hide 
problems that may arise when I use the same kernel on plain 
Windows ?

Of curse you can run coLinux inside a VirtualBox machine.

You should run XP (not Linux) inside VirtualBox to have the same host OS 
for coLinux:
Any OS (Windows or Linux) --> VirtualBox --> Windows XP --> coLinux

Please enable Physical Address Extension ("/PAE" in boot.ini file), if 
your "stable" Windows also use it. You can see "Physical Address 
Extension" after pressing Windows+Pause.

There are no hiding problems from inside VirtualBox.

Henry, it worked fine with a 2.6.22.18 kernel compiled using GCC 
4.3.3.

But running a 2.6.25 kernel compiled using your patches, I got

colinux: error, expected kernel API version 13, got 11
error initializing
daemon: exit code 82c6fc03
daemon: error driver version, please reinstall driver!

Is it because the 4.1.2 x 4.3.3 ?

But why 2.6.22.8 is accepted by the daemons and not 2.6.25 ?

The patch series was to old. We have changed a lot on the passage page, 
that's why we have increased the API to 13 now. This avoids a crash of 
your host system. ;-)

Patches have updated now on:
http://www.henrynestler.com/colinux/testing/kernel-2.6.25

Please run a "make clean" after adding the new patches for kernel 2.6.25.

Please remember to enable the patch gcc412fix.diff in the file 
patch/series-2.6.25, if gcc 4.1.2 is your local compiler for kernel builds.

Thanks. It compiled and worked fine. I'm using GCC 4.3.3. I had 
patched the 2.6.22.18 sources with http://git.kernel.org/?p=linux/kernel/git/stable/stable-queue.git;a=blob;f=queue-2.6.24/time-prevent-the-loop-in-timespec_add_ns-from-being-optimised-away.patch;h=489cbdaa36a065ee536b73f53b7cba8a8e8635bc;hb=cf3242783319c215e3d2e59e293e9c307724cea5

Henry, do you get networking support with the 2.6.25 kernel ? 
Here, lo comes up, but not eth0.

In VirtualBox I'm using the Debian 5.0r2 image with slirp. I 
also tried pcap and tuntap, but eth0 doesn't come up.

If I boot with the 2.6.22.18 vmlinux, it comes up.

Thanks. It worked fine, also compiling with MK8. So, I guess 
it was a GCC 4.3.3 x 2.6.22.18 issue.
