Hey, 
my team is working on adding AoE protocol support to ovirt. 

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. 



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. 

<blockquote>


2. for ISOs to be available, i need to enable hosts configured in clusters and storage domains of ATA type. (currently NFS, iSCSI and FC are done). which files should i focus on changing for above functionality. 

</blockquote>

I've never heard of ATA network storage. Are you referring to ATA hardware technology, i.e. SATA? 

At any rate, adding a custom storage domain technology will difficult. Hopefully someone else on list can direct you. 

<blockquote>


3. How do i change the custom layout of the engine? (like adding a few extra buttons.) please specify the files responsible. 

</blockquote>

Again, you'll need to read up on oVirt's UI Plugin infrastructure. http://www.ovirt.org/Features/UIPlugins 

<blockquote>


4. the above questions stress that am facing difficulty in identifying files responsible for a particular module. is there a better way to do that instead of digging up the entire source code. ( a documentation if available.) 

</blockquote>

Other than what we've already mentioned (JavaDoc, architecture docs on the wiki), no.

Aditya, 

That is because that file doesn't exist. We map that name to a servlet in 
web.xml. If you want to modify the GWT host page take a look at 
GwtDynamicHostPageServlet.java and its sub classes (for user portal and 
webadmin). As well as GwtHostPage.jsp. You will find there is almost nothing in 
that page as all the HTML is being generated at runtime using GWT. 

Since you are not really explaining what you are trying to do we can't help 
you better on the best strategy to achieve what you want.
