Procedure D.2. Deploying a Hello World! Plug-in

  1. Create a plug-in descriptor by creating the following file in the Manager at /usr/share/ovirt-engine/ui-plugins/helloWorld.json: 
    {
    "name": "HelloWorld",
    "url": "/ovirt-engine/webadmin/plugin/HelloWorld/start.html",
    "resourcePath": "hello-files"
}
  2. Create the plug-in host page by creating the following file in the Manager at /usr/share/ovirt-engine/ui-plugins/hello-files/start.html: 
    <!DOCTYPE html><html><head>
<script>
    var api = parent.pluginApi('HelloWorld');
    api.register({
	UiInit: function() { window.alert('Hello world'); }
    });
    api.ready();
</script>
</head><body></body></html>
If you have successfully implemented the Hello World! plug-in, you will see this screen when you sign in to the administration portal:
