[coLinux-devel] Dual boot vs. coLinux setup

[Ronald P. <pij...@ds...>]

Hi all,

After tweaking reiserfs a bit (so it will not be stopped by a zero sized 
device :-), I started my natively installed Gentoo distribution for the 
first time. Then I ran into a couple of problems.

/etc/fstab has an entry for / on /dev/hda6, but suddenly this has become 
/dev/cobd0. Although I can specify this in default.colinux.xml, during 
init it is remounted based on fstab. Some similar problem happens for 
the swap device and cd-rom. Has anyone an elegant solution for this?

I manually edited fstab to accommodate said problem, then rebooted. This 
went fine :) . Hoera!
That is... all services start (although I seem to have to press the any 
key a few times). However, when I get the login promt everything 
freeses, including Windows (XP Pro).
I guess that this can be related to the CFLAGS settings that I use for 
Gentoo (includes -march=pentium3 -mcpu=pentium4), but that is just a 
guess. I didn't expect Windows to freese either. Any comments?

All in all, I'm slowly getting where I want to get :)

Ronald.

This is exactly what my topologilinux howto acomplishes on the coLinux
wiki page but that is for a slackware based distro on a loopback
filesystem. I use the fact that /initrd the mount point for the initrd in
a native boot is not used by coLinux mode.

hprofile can change configuation files for different boot methods but this
can only be done after / is rw

If you are not using an initrd for native boot you could create a do
nothing initrd for native boot mode that just has a linuxrc that does the
pivot root see the initrd.txt file in kernel source documentation.

I would recomend getting the second problem fixed with your manually
edited fstab first before going on to my other sugestion.

My guess is that gentoo is trying to start x at that point?  or doing 
some other framebuffer operation?  If so, that is what is causing the 
freeze.  Colinux doesn't yet support linux trying to use your display 
adapter.

RE: [coLinux-devel] Dual boot vs. coLinux setup

[Daniel R. S. <dan...@ya...>]

I ran into the same issue with /etc/fstab for my dual boot fedora
installation. What I did was to create a small (250MB) file to use as a root
partition. This I booted the debian image under colinux, mounted my fedora
partition and the root file. Then I copied /etc, /bin, /sbin, /lib and
/lib/modules from the fedora partition to the root file. I created a
directory /.fedora on the root file, changed /etc/fstab on the root file to
mount /dev/cobd0 on / and /dev/cobd2 on /.fedora. Then I created symbolic
links for the rest of the directories in / that pointed to the corresponding
directories on the fedora partition. 

 This seems to work great for me. I can run fedora either under colinux or
natively.

If you set inittab to boot to runlevel 3 that would probably be the
easiest way to find out if X is the problem. If that is it and you later
decide that you would like an X login then the solution I gave for fstab
would work for changing out inittab and if you want to use an xdmcp
solution for cygX or vnc then you could use my method to swap out the
config file for xdm or gdm there is a setting there for not creating a
local display which you could set in the coLinux version of the file.

Hmm... that´s a mighty lot of files in one sentence. I think I 
understand what you´re getting at. I´ve been reading the Gentoo init 
documentation, and I´ve got the feeling there´s quite some interesting 
things to do with that. E.g. I could define a complete extra 
(soft)runlevel for booting coLinux. With a kernel parameter 
softlevel=coLinux it would boot into this runlevel. This should allow 
for doing some of the right things. Combined with your initrd boot 
option, I should be able to make this work.

Thanks for the input.

Yes, you´re very right. Booting with ¨single¨ lets me run Gentoo nicely. 
In fact, this mail is currently typed from Remote X-ing into Gentoo 
inside coLinux in WindowsXP :)

Getting there...

Im very curious about the freezing part, im currently using gentoo in a 
10GB image since i have yet to manage to find a livecd (reg gentoo and 
knoppix fail to see the ricoh fireiwre adapter in this Sony laptop) to 
partition and format a 13GB area that is unused on my firewire drive, 
but back to the freezing i have problems when compiling in gentoo and 
after X number of packages my laptop simply shuts down.
My first thought was over heating, a thought i discarded since i was 
able to create more heat and for a longer time when repacking several 
images i used for colinux and wanted to have backed up since one of 
those shut downs rendered two images unusable before
you use -march=pentium3 -mcpu=pentium4 which should elegantly give the 
most optimized gentoo for a P4 while not having to worry about 
-march=pentium4 now correctly generating code or not (a problem in the past)
i would like to point out i have had those shutdowns very frequent when 
using -march=pentium4 (i am trusting gcc 3.3.2 there) and still managed 
to get one since trying it all again with just -march=i686 -O2 
-fomit-frame-pointer -pipe

if anyone else has problems with freezes and or shut downs on P4s i 
would like to hear about it

As just posted in another mail, the freezing was related to Gentoo 
accessing the framebuffer. I´ve had no problems in the course of this 
evening (on a HT machine even).
