New subject: [Users] adding scripts
may I ask what is the general purpose of these buttons that you
would like to add and where (in the GUI) would you like to add
them?
if you would like to add buttons to existing main-tab(s) / sub-
tab(s), the way to go is to write a UI Plugin that does that
(especially if you intend these buttons to do something very
specific for your needs).
If you would like to add these buttons elsewhere, you will
need to follow Greg's instructions and dig into the code for
the specific needed location.
I want to commit changes to the engine...
note that we can push into the code only things that make sense
to include in oVirt (i.e. things that will be useful for typical
oVirt users); again, if these buttons will do something very
specific for your own needs, you should definitely utilize the
UI Plugins infrastructure instead.
... and make few tweaks for personal use...
if these tweaks are in the "branding" area (i.e. if you want to
change main color themes, top-left image on the top banner, etc),
then writing your own branding [1] is the way to go [you can
override only part of the branding (depending on what you would
like to tweak), you don't actually need to come up with a
complete alternative branding].

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.

make few tweaks for personal use? I just cant find that file after using
git.

if you are trying to hook into UI-specific events, it sounds
like you will need to write an oVirt UI Plugin [1] in order to
do that. However, I believe that the oVirt UI Plugins
infrastructure doesn't support hooking to events such as "tab
x was selected" and/or "button b was clicked".
It does allow you to add new (custom) tabs/sub-tabs/buttons of
your own, and there is a chance that it allows you to hook
into events such as 'row x was selected in the grid'.
@Vojtech will know better. Vojtech?
if you are trying to hook into engine events (e.g. you want to
run a script every time a VM is started in oVirt, no matter if
the user started it by clicking the 'run' button in the oVirt-
engine webadmin, or invoked a REST API request, or an SDK
command), then it will require some sort of an "engine-plugin"
infrastructure that we don't have at the moment AFAIK.
there is a chance that for some of the events you will be able
to utilize the VDSM hooks (at the Host level) [2].

New subject: [Users] [Engine-devel] adding scripts
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.
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.
3. How do i change the custom layout of the engine? (like adding a few
extra buttons.) please specify the files responsible.
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.)

That is because that file doesn't exist. We map that name to a servlet in

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

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.

[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

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)
Javascript. But remember the UI plugins are running javascript in your
browser, and don't directly communicate with VDSM.
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

Note the VDSM hooks have nothing to do with the UI plugins. The VDSM hooks
alter the way VDSM works. The UI plugins alter the way the UI works. The
engine sits in between the UI and VDSM. Basically the UI issues a command to
the engine, then the engine issues a command to VDSM.
For UI plugins it is easiest to communicate with the engine using the REST
api. So your instance your UI plugin has a button, which when you click it
issues a REST api call. The REST api call is part of the engine. The engine
creates a command based on the URL and parameters of the REST call and uses
that command to make a call to VDSM. Once the call reaches VDSM then the VDSM
hooks come into play.
So I don't entirely understand what you are trying to do, but you might have
to write some code in the engine to create the appropriate command to pass to
VDSM. In addition to the UI plugin and the VDSM hook.

Javascript. But remember the UI plugins are running javascript in your
browser, and don't directly communicate with VDSM.
Yes, this is an important point. Typically, you invoke operations on hosts through
Engine's REST API.
As Alex mentioned below, you can also install custom VDSM hooks, these are invoked at
certain points of VM lifecycle: http://www.ovirt.org/VDSM-Hooks

============

Iam left with two questions:
1. is the plugin to be Java or JavaScript? (I think the answer
is the latter)
Right, UI plugins are written in JavaScript as their code is dynamically loaded during
WebAdmin startup.
Your UI plugin is technically a web application on its own, except that plugin host page
[1] is rendered inside invisible <iframe> element.
[1] plugin host page = HTML page responsible for loading actual UI plugin code (no markup,
just logic)
UI plugin code can make HTTP requests just like any other web application. This is how you
would invoke operations on remote servers.
The easiest way (I think) is to add custom CGI/Bash script into Apache which sits in front
of Engine (JBoss AS) server in a typicall oVirt deployment. Your UI plugin would simply
hit URL mapped to custom CGI/Bash script, which would execute whatever command is
necessary.
Alternatively, you could deploy custom Java web application (*.war) inside Engine Java
deployment (engine.ear) so that it co-exists with existing Engine web applications (REST
API, WebAdmin, UserPortal, etc).
Finally, a totally custom alternative, run your own HTTP server, enable CORS [2] for
requests from Engine origin, and have your UI plugin talk to this custom server.
[2] http://en.wikipedia.org/wiki/Cross-origin_resource_sharing
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
Correct, UI plugin itself is JavaScript, it makes no assumptions of server-side
technology.
It is up to UI plugin developer to decide if/how the plugin should communicate with remote
servers (Engine REST API, call Apache CGI, call custom server, etc).

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

be possible). can you help on that? which programming language should i
use, and how that file should be invoked.
When you say ovirt portal I am assuming you mean the web admin as giving users
access to low level stuff like that in the user portal would probably be a bad
thing.
As said in a couple of other responses the best way to do that in webadmin is
probably writing a UI plugin. A full explanation of what you can do with a UI
plugin is available here: http://www.ovirt.org/Features/UIPlugins
In short a UI plugin is a mini application written in Javascript that hooks
into the main web admin UI. The UI infrastructure makes certain element of the
UI available to the plugin. One of the things it can do is to allow you to add
buttons to the UI. When those buttons are clicked whatever javascript handler
you assigned to it will execute.
This gives you a couple of options:
1. Write your own web application that can take commands from buttons inside
the web admin interface. Since the ovirt engine runs on JBOSS I would suggest
you write your own web application in Java that executes the appropriate bash
commands based on which button is pressed using the UI plugin.
2. Write a minimal plugin that makes use of the REST API and add code to call
your bash scripts from the REST api.
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.
Honestly I don't know enough about the storage infrastructure to give you a
good answer to that. Maybe someone else can fill this in.
3. How do i change the custom layout of the engine? (like adding a
few
extra buttons.) please specify the files responsible.
Look at the UI plugins, the page linked above explains their usage in great
detail as well as give a bunch of examples on how to achieve this.
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.)
This gives a nice overview of the architecture of oVirt:
http://www.ovirt.org/Architecture
The source code associated with that is basically split out into two GIT
repositories.
1. For the frontend and the engine, which is all java code.
2. For VDSM which is all python.
The user portal and web admin communicate with the engine using GWT-RPC and
soon the REST api. Then the engine communicates with VDSM using XML-RPC.
The engine runs on one machine (either dedicated or as its own VM on one of
your hosts). Then VDSM runs on the hosts. The hosts are the ones that
communicate with the storage. So I am guessing your bash code will run on a
host?
So in short, I think this is what you want?
1. Write UI plugin to add the buttons/etc to the webadmin.
2. Write your own web app, or hook into the REST API and add the commands to
execute whatever it is you are doing.
3. (Maybe?) Modify VDSM to accept the commands from the REST API or your web
application, and execute your scripts using VDSM based on the commands.
