Thread: [coLinux-devel] 2.6 kernel ?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hi guys!

Does coLinux support 2.6 kernel as a guest OS ? Is there a patch =
available for 2.6.5? I'd like to use NTPL and it seems non-obvious with =
2.4 kernels...

Nope -- colinux is not an emulator like VMWare, but (in part), a linux kernel 
that has been modified to run under Windows (and now Linux) using some 
"trickery" analagous to User-Mode Linux.  That's why it's faster than VMWare 
-- look Ma, no emulation!  The upshot is: to achieve this, one has to port 
the coLinux kernel patch forward to 2.6.  Presumably this is nontrivial, or 
Dan would have done it already.

Sorry about the "guest os" term. I think I know how colinux works.

Question to Dan: do you plan to port colinux to 2.6?

Looks like I may have been wrong anyhow; the latest snapshots claim 2.6 
support; looking into it...

I have to correct you; The latest snapshot can run *under* Linux 2.6.x as 
the host operating system, not *run* Linux 2.6.x as guest.

Aha, thanks for this clarification, which is sure to save me some 
head-scratching time!

I shouldn't volunteer for anything, since I am already slacking at my existing 
volunteer projects.  So, for the moment, I will just stick to heaping praise 
upon the contributing coLinux developers (i.e.: thanks! you are studs!).

A more pressing project might be to fix the known deficiencies in 2.4 coLinux, 
such as the limitations with reiserfs, "raw" partition access, entropy 
gathering for /dev/random, etc., or to help the ReactOS folks with their 
ongoing efforts to make coLinux a Windows subsystem... not that I am 
volunteering for any of those either :-P  Perhaps a good use for the Wiki 
would be to begin sketching out the landscape of un-finished coLinux 
projects....  hmmm...  well, I'd better shut up before I start volunteering 
for things!

virtual beer,

That port is just waiting to be done by either me or anyone who volunteer.
