Re[2]: [coLinux-devel] potentially bad idea

ESJ> What I am hearing is that I can run the same kernel both as a guest and native.

If  you  mean  under the word "same" the version number then yes, you are right.
Actually  it's  very  simple-  the  main part of coLinux is kernel 2.4 with some
patches  applied. You may run it under Windows and native Linux as well. But you
can't boot the native Linux with the same vmlinux file which is used by coLinux.

AFAIK, under coLinux all IDE block devices are accessed via cobd driver. I
remember reports that it's even possible to mount CDROM under Windows as soon as
it's not in use by Windows itself, i.e. no one files opened from it.

Under coLinux It looks like that:
userApp -> coLinux virtualisation driver -> native OS driver (1) -> hardware
Where (1) is either Linux driver or Windows one.

I have two disks in my system. In pre coLinux times I've installed gentoo as
alternative OS. After discovering coLinux I put the line
<block_device index="0" path="\DEVICE\Harddisk2\Partition1" enabled="true"/>
( /root ) into default.colinux.xml and start coLinux under Windows.

So, it have to be defined what OS is by itself- a kernel only or
a kernel + all daemons and user apps.

As I've mentioned above all devices should be wrapped by coLinux visualization
driver. Please correct me if is's wrong.

Take a look here, may be you'll find something interesting:

And pay closer attention to this one:

ESJ> np, startx works for me.
Oops... how it looks like? Can you post a screenshot, please?
