vnc is always slow on windows. There are a few thing that you can try

- tight vnc, beter encoding/compressing and single cursor
- ultravnc with high speed mirror driver (for the display)

The vnc performance is very poor, also the real cursor and the vnc

What can be wrong? How I can fix this?
Fabian,

probably nothing wrong, just the way things go with that kind of setup. It just works - but not more.
For (possible) optimizations have a look here:

Thank you for your answer andrej, I will try out the described
optimizations from the user manual.
I hope there will be another method to administrate the virtual machine
over network. The SDL console is better useable over SSH X11 forwarding
than VNC, the only problem is that I can't attach the console. :/
An attach function would be fine.

Otherwise I would strongly suggest you go for some kind of RDP remote connection, like using rdesktop if you are sitting on a Linux client.

Yes RDP works fine, I'm allready using it. But only works if the guest
OS is allready seted up.
greetings

Fabian
