[coLinux-users] Colinux without adminstrator

[Julien L. <jul...@gm...>]

Hi,

I'm looking for a way to run Colinux on a machine without a
administrator installation. I read the FAQ
(http://colinux.wikia.com/wiki/CoLinux_FAQ#Q0._Do_I_need_Administrator_rights_on_my_Windows_computer_.3F)
and it appear it's not possible ... But i'd like to know why ?

If i understand correctly, Colinux need an administrator to install
the Colinux driver (monitor) which is used to run a low level process
in Windows.
So what does that mean ? That mean if you are not the administrator,
you can't run a low level process ? So is there possible to run
Colinux as a high level process ?

I'm really sorry if my questions are stupid but i'm not familiar with
the Windows process behaviour so i'm not sure to understand what is a
"low level" process.

Thanks in advance

PS: Ulteo Virutal Desktop beta was released last week. It's using
Colinux (like AndLinux but don't use it), pulse audio and Xming

Yes,  colinux needs to access to some low-level, for example setting
page-tables.
It is not possibile use it without the driver.
What you need is a win32 of uml, or umlwin32.
But I don't know if it is usable. And it is not updated.

I know. But for now we don't have other way.

Would'nt be "bochs" helpfull?
AFAIR it emulates every command, not needing the native CPU.
QEMU is similar.

I assume wikipedia will list them all.

Oooops- CoLinux has a GUI?

The administator needs only to install the driver.

Yes.

No. You can't install ist, but you can start it, if installed by an admin.

>So is there possible to run Colinux as a high level process ?

If your admin installed the driver: yes.

"low level" has direct access to all hardware for example.
Direct Access to hardware is not possible for "user", they MUS use
a driver which controls the access rights.

With "low level" here means the cpu "ring 0" there the coLinux kernel
runs. CoLinux is not an emulation and not a virtualisation of a cpu.
Colinux use the cpu and needs to have full access to all registers on
your cpu. That only can do, if an administrator has installed the
lowlevel (ring 0) driver.
