Hi guys,

this should be easy enough to launch another window with the requested url.

Indeed, but you might also want to override UI logic for handling "open console" functionality for VNC protocol in WebAdmin: [in MainTabVirtualMachineView, around line 223 that adds ConsoleModel-bound action button] getTable().addActionButton(... { @Override protected UICommand resolveCommand() { ConsoleModel defaultConsoleModel = getMainModel().getDefaultConsoleModel(); final UICommand defaultConnectCommand = defaultConsoleModel != null ? defaultConsoleModel.getConnectCommand() : null; if (defaultConnectCommand != null && defaultConsoleModel instanceof VncConsoleModel) { // Replace default VncConsoleModel's Connect command with custom functionality return new UICommand("Connect", null) { @Override public boolean getIsAvailable() { return defaultConnectCommand.getIsAvailable(); } @Override public boolean getIsExecutionAllowed() { return defaultConnectCommand.getIsExecutionAllowed(); } @Override public void Execute(Object... parameters) { if (!getIsAvailable() || !getIsExecutionAllowed()) { return; } WebUtils.openUrlInNewWindow("Custom popup window title", "url from novnc-server"); } }; } else { return defaultConnectCommand; } }); Regards, Vojtech ----- Original Message ----- From: "Itamar Heim" <iheim@redhat.com> To: snmishra@linux.vnet.ibm.com Cc: "Ohad Levy" <ohadlevy@redhat.com>, "Vojtech Szocs" <vszocs@redhat.com>, engine-devel@ovirt.org, "Adam Young" <ayoung@redhat.com> Sent: Thursday, September 20, 2012 8:44:05 PM Subject: Re: [Engine-devel] Frontend questions.

Hi,

I am looking at adding support for novnc in ovirt. I have not worked on the frontend and thought of asking some questions to the list to save time.

Currently, when a user selects to open console on a VM with VNC. They get a popup window with IP, port and password for VNC session. I plan to take this info to host and run the command -

novnc_server --vnc IP:(port-5900)

This command returns a URL, use this url to open a new browser window which will be a vnc session to the VM.

My questions are -

1. How to run the novnc-server command on the host?

i can't say i like the idea of launching these on the engine, but we can start with making this work first with these limitations. hopefully these aren't too resource intensive. ohad - how do you deal with this in foreman? adam - i saw you pushed these rpms to fedora - can you share how this is launched in openstack? on the technical side, you can launch an external process with the relevant parameters. though we probably need to consider how we could do this not via shell locally, rather via a remote call to allow setting this up on another server than the engine.

2. How to open a new URL for VNC session?

this should be easy enough to launch another window with the requested url. vojtech?

Thanks Sharad Mishra
