I have RHEL6 guest with 2 vMonitors. (Multi-Monitor)
(same happens with other distros)

With GNOME, I can easily make them work, but with KDE4, I can't.

KDE Control Panel->Display->Configure KDE for multiple monitors -- is always grayed out.
I tried to go to
KDE Control Panel->Display->Size & Orientation->Resize and Rotate your display
here I see two monitors (VBOX0 and VBOX1), but no possibility to configure them, so they always work in "MIrrored Mode".

Any ideas?

I don't have RHEL 6 installed but they should be close to the same on openSUSE KDE. Anyway this works for me.

Configure desktop -> Computer Administration -> Display See screen shot for settings. This will stop the mirroring and emulate two or more monitors.
I also noticed that I had to remove the openSUSE GAs and install the VirtualBox GAs (4.0.4) before it would work for me, but I am not sure if newer openSUSE GAs work or not. The version that was preloaded on mine was 3.2.*.

Thanks.
This worked after second time. On first time, those settings refuse to apply for some strange reason.

Would you send me your working X conf (for guest)?

I was able to setup a big screen on my 2 virtual monitor (window) where the x resolution was 2x1024 pixels (2x 1024x768 resulution) with SuSE 11.4 Gnome LiveCD.
So the X was a big 0:0 screen. Can I setup a :0.0 and :0.1 screens? Under Gnome the only possibility was unmirror the monitors.
A config example would be very convenient for me.

TIA,

Guest does not use xorg.conf

OK
What does it use then?
X is running.

I'm absolutelly confused that "multimonitor" feature.
I get 2 windows which seem to me it looks like a dualhead setup.

I don't want to use real 2 monitor system. I just want to virtualize it in guest.
Could you explain it for me?
Under Vista it works like dualhead. I don't understand.
I configured a real 6 monitor Linux machine where there are 3 VGA cards each 2 heads. I'd like to that config of course without 3 VGA card but with 6 monitors.

TIA,

If you set the guest to have (2) monitor count, and if you follow the above suggestions, you will have (2) displays on your desktop.
These resemble (2) monitors and function as that on your main (hosts) display if you do not have a multi monitor enabled host.
You can set to as many you want (up to 8 ) as long as you follow the memory suggestions that VirtualBox tells you to use.

OK, I understand and it is working now.

Sorry for my stupidity but I don't understand.
I install a Tinycore Linux with X as guest. On :1 monitor there is the desktop and :2 is empty or blank (black).

First step: I want to use :2 in any mode (mirror, different screens, anything). I think I have to modify the X configuration to reach that goal? Do you agree?
Second step: I want a big continous screen on the whole 2 "displays".
Third: different screens, maybe different resolutions.

Can I solve those goals?

So I want to separate VBox config from X config on guest. I think my VBox config is ready and working. X is not.

OK, it is clear. For my understanding 2 monitors are enough.

TIA,
