Fast VNC

[Jun OKAJIMA]

Hello.

I have an interest in using VNC as console of virtual machine like Xen.
The outline is like this. You make multiple VMs on a PC, and then connect
them with VNC. So far is okay. This way works well. Thanks.

But, it is a bit slow. In this case, I dont need any textile compression,
even I dont need inter-process-communication. Just shared memory is enough.
I mean, you make shared mem as a virtual frame buffer and then update a
modified rectangle periodically. This is very simple, but will work well.

Do you know how to do something like this with VNC?
Or, do you know another software (not VNC) for this purpose?

TIA,
