![]() ![]() ![]() This requires adding event listener “message” to the page. noVNC client changesįor our purposes, the noVNC client html page must listen to VNC information passed from the engine using HTML5 postMessage. There are two changes that must be made to noVNC client and websockify. noVNC client and python-websockify customization The websockets proxy reads data from the path and establishes connection to the VNC server. Now the VNC information (vnc host:port, ticket) must be passed to the proxy to know where to connect. As soon as the client receives the information, it connects to websockets proxy which runs on a particular host:port. For passing such information, the HTML5 window.postMessage function can be used. Upon establishing the VNC session, the noVNC client (HTML + js) must know where to connect. The noVNC client is a html5 page with javascript which talks to websocket server (e.g. As soon as it's merged, we should switch to using this feature instead of standalone websockets server). (Note: There is a patch that integrates websockets directly to qemu, but it will not be merged into DS at the time we need it to be there. This proxy can run either on any node that has access to the host network, or it can run on each host. However, VNC server in qemu doesn’t support websockets natively and there must be a websocket proxy placed between the client and VNC server. The noVNC client utilizes websockets for passing VNC data. There is no need for users to have a native VNC client installed when using noVNC.Enhanced options for connecting to virtual machine consoles in oVirt.Email: Engine part of implementation (loading noVNC client and making it connect to websocket proxy using postMessage) - DONE.The aim of this feature is to make it possible to connect to VM consoles using HTML 5 VNC client called “noVNC” in browsers supporting websockets and HTML5 postMessage function (webkit browsers, Firefox, IE > 10). They are not user documentation and should not be treated as such.ĭocumentation is available here. Most of them are outdated, but provide historical design context. ![]() Feature pages are design documents that developers have created while collaborating on oVirt. ![]()
