Summary: strange mouse behavior when connecting to kvm-sesion via vnc

Initial Comment:
I've a few running kvm-sessions on my server (fedora, ubuntu and winxp). I can 
connect to them via vnc which i enabled in kvm (via kvm -vnc).
The problem is that the mouse in a kvm-window is never there where it should 
be. This is really annoying because, for example if i try to press the start 
button (in windows), most of the time my mouse is already out of the window. I 
always have to "play" with the mouse to reach the button. Generally its with 
everything i do in windows with the mouse. Its the same with the other 
linux-oses.

It seems it depends on which point i jump into the window. Also the mouse 
distance between the local mouse and the mouse in windows changes while i move 
the mouse in windows.
I already made an bug-report on bugs.kde.org, because i though it's the fault 
with krdc (which is my vnc client), but i have the same issue with other 
clients too.
Here is the link of the bug-report: https://bugs.kde.org/show_bug.cgi?id=212498

I've my own simple start-script for my kvm-machines. I'll post my configuration

        eend $? "Failed to start ${VM_NAME}"
}


I hope thats enough info :)
