the threading is not clear to me, and I hope I have the attributions correct On Fri, 21 Mar 2014, Greg Sheremeta wrote:

am thus facing following difficulties:
1 : i wrote the required code using in bash scripting, which i wish to invoke after a click of button in the ovirt-portal. (which does not seem to be possible). can you help on that? which programming language should i use, and how that file should be invoked.
[I think Greg said:]
This needs to be done in Java. You'll need to read up on oVirt's UI Plugin infrastructure, which Einav and others mentioned below. No, you cannot write a bash script and have a button click in oVirt invoke that.
Reading this: http://www.ovirt.org/VDSM-Hooks it states as a pull quote: The hooks reside on every host in /usr/libexec/vdsm/hooks/ A hook can be any executable (bash/python/perl/binary/etc). and then at: http://www.ovirt.org/Features/UIPlugins UI plugins integrate with WebAdmin directly on the client (web browser) using JavaScript programming language. Plugin invocation is driven by WebAdmin and happens right within the context of browser's JavaScript runtime, using JavaScript language as the lowest common denominator between WebAdmin (GWT) and individual plugins. UI plugins can take full advantage of JavaScript language and its rich ecosystem of libraries. There are no specific rules on how to implement UI plugins, plugin API is designed to be simple and not to get in developer's way, regardless of how a developer chooses to write the plugin ============ I thought I understood the model, but have gotten confused. Iam left with two questions: 1. is the plugin to be Java or JavaScript? (I think the answer is the latter) 2. is there a constraint as to implementation language, or not. I think a JS wrapper can call whatever it wishes, but this is not clear to me Thank you -- Russ herrold
