+#XXX-Cedric : Currently, one can only access to KVM using noVNC.
+#             Ideally one should be able to access KVM by using either NoVNC or VNC.
+#             Problem is : no native crypto support in web browsers. So we have to disable ssl
+#             In qemu builtin vnc server, and make it available only for localhost 
+#             so that only novnc can listen to it.
+
+#XXX-Cedric: Check status of https://github.com/kanaka/noVNC/issues/13 to see
+#            When qemu has builtin support for websockets in vnc server to get rid of 
+#            Websockify (socket <-> websocket proxy server) when it is ready.
+#            May solve previous XXX depending on the implementation.
