In this talk, I will introduce Guacamole, a HTML 5 based VNC service that allow user access their VM screen in web browser without install anything. The research part also shows how guacamole will connect VM runs on Xen hypervisor, and show a demo to make our dev version of Guacamole connect to a VM on VMWare.

4. Short Discusses
 Windows RDP issue with Guacamole
 We do not need to extend guacamole to provide
RDP support since we can directly useVM’s
console screen
 Xen limitations
 Only one console can be display at the same time
