[Engine-devel] Unable to add second Data domain to my Data Center.
Hello,
I am trying to setup a host for a seperate oVirt engine/node environment
(version 3.1). I managed to get my host up and running and active in my Data
Center. I managed to create 4 storage domains on that host. 2 Data domains and
1 ISO domain and one Export domain.
I am successful in attaching the ISO/Export/smaller Data domain to my Data
Center. The web admin interface is indicating they are active. I activated my
smaller test Data domain because I was having some issues earlier getting my
storage attached. I worked through those issues and now I want to attach my
actual Data storage so I can detach the test one. Whenever I attempt to attach
the storage I get an error message and when I look in the vdsm log I see the
following:
Thread-2801::ERROR::2013-01-17 16:55:22,340::task::853::TaskManager.Task::

Which seems to indicate the disk is full. Which is not the case as this is a
brand new machine with a fresh install and a 1T drive in it. The error does
point to sanlock so when I look at the sanlock log I see this:

I googled around for that particular error message and I couldn't find anyone
with any suggestions as to the source of that problem.
Could someone please give me a pointer of where to look or help me debug the
issue.
Thanks,
Alexander

[Engine-devel] Latest open jdk and JBOSS
Just an FYI there is an issue with the latest openjdk and JBOSS which causes JBOSS to NOT start. Details can be found here: https://community.jboss.org/message/796347#796347 I did upgrade yesterday and I am having the exact same issue. For now do not upgrade your open jdk to the latest version.

Make sure you update your database, I had the same thing, I had a missing entry or table or something, once I updated the database and restarted jboss it was fine.

Re: [Engine-devel] How get all language WebAdm ?
You need to compile GWT with the appropriate language profile. If you want to compile with all languages make sure to include the all-langs profile in your maven build command. for instance: mvn clean install -Pdep,gwt-user,gwt-admin,all-langs Be aware that compiling all languages will take a long time ~30 minutes on my machine. You can specify particular languages to cut down on compile time. Alexander On Wednesday, April 17, 2013 09:27:25 PM 李强 wrote: HI：All I install ovirt engine and open IE9 to manage.

Once you have the engine up and running as explained about, you can use
http://www.ovirt.org/DebugFrontend to run GWT debugging. You can safely skip
step 0
in that document (I think that needs to be updated). And start at step 1. The
document explains quite well what to do, but the short version is:
1. cd into the source code directory of either webadmin or user portal.
Usually: ovirt-
engine/frontend/webadmin/modules/(webadmin or userportal-gwtp)
2. mvn gwt:debug -Pgwtdev,gwt-admin,gwt-user -Dgwt.noserver=true from the
command line. Once it is done compiling it will tell you it is listening on
port 8000.
3.In eclipse (or your favorite java IDE) make a remote java application
connection to
port 8000
4. Once connected this will open up a GWT debug window.
5. In your browser as ?gwt.codesvr=127.0.0.1:9997 to the url you are working
with and
refresh the page.
6. It will either ask you to install the plugin in your browser or load the
page depending
on if you have the plugin already.

No it is a normal java application (The GWT debugger).

The GWT debugger is completely agnostic with regards to what serves the host
page. The GWT debugger is connected to the browser, not the server. The host
page can be served from a local JBOSS, a remote Apache, a file, whatever. The
GWT debugger doesn't care as it is talking to the browser.
IMO the only thing we could do to improve this is update the make file to
provide a target to start the debugger, which basically just calls maven with
the appropriate parameters.

[Engine-devel] Introducing limited branding support.
Hi Guys, We recently merged at a patch (http://gerrit.ovirt.org/#/c/13181/) that allows for limited branding support of oVirt user portal and web admin. We also moved the styles needed to support this branding out of the application and into its own module. The styles can now be found in ovirt- engine/packaging/branding/ovirt.brand. In this directory you will find the following files: - branding.properties. This file controls the branding theme. - ovirt_messages.properties. A standard java resource bundle properties file containing the messages that can be changed. - A bunch of .css files that contain the classes that can be altered. I have created a wiki page with some information and pictures of what parts of the interface can be changed at this point in time. It is located here: http://www.ovirt.org/Feature/Branding There is also more information in README.branding that got introduced with this patch. Alexander ps. If your user interface looks messed up (missing borders and things of that nature) the engine cannot find the default branding. This means you are not using the make commands recently introduced. We highly recommend you use this to have a complete environment. If you are unwilling or unable to use that you can make a symlink in /etc/ovirt-engine/branding/00-ovirt.brand to ovirt- engine/packaging/branding/ovirt.brand ___ Engine-devel mailing list Engine-devel@ovirt.org http://lists.ovirt.org/mailman/listinfo/engine-devel

The only reason we did it like that, is that there is no other way of changing some of the messages at runtime. If there was some way of doing it at compile time I would have done that. Also the number of resources changed by branding is very limited and therefore won't impact the performance as much as doing every single resource. There are advantages and disadvantages of both methods that need to be carefully weighed, and the GWT developers themselves did that and came to the conclusion that compile time inclusion is the best method for most resources.

However for the user not so much, and in the end we are creating the software for the user and the needs of the developer are secondary to that.

As noted this seems to only happen with FF 17 ESR, which is the current EL6 version. If I use firebug or attach a GWT debugger, the problem goes away. Heck if I compile GWT in draft mode the problem goes away. I did however make some progress yesterday in determining the cause. It seems to me that for some reason revealDefaultPlace in the user portal is called multiple times and in certain cases the second time the method is called it never finishes which causes the behavior we are seeing. Still no solution, but this is my top priority to get working.

Re: [Engine-devel] IMP: Regarding an issue while translating the error messages for gluster using ErrorTranslator class
Looking at the code, if you start the error message with a $ it will not do
the . to _ replacement. Not sure if your error message will now simply start
with a $, but it is worth a try I guess.

Re: [Engine-devel] [UX] how to design a bar/line chart?
I suppose we need to answer a few questions before we can go into which library is better: 1. Do we mind sending data over to Google so Google can render images for us. 2. Are we fine with just an image being displayed in the grid? If we aren't okay with #1, we will have to create some sort of servlet to generate the images. 3. Do we want the client to render the spark lines using javascript? 4. Do we want interactivity with these visualizations? For instance if I move my mouse over the spark line, does the value displayed change? 5. Can we display whatever we choice in our current grid implementation?

[Engine-devel] UI Refresh synchronization
Hi guys, I am working on providing our users with a better experience in regards to refresh synchronization. Quite often it will happen that you as a user will do a particular action, and it takes a whole refresh cycle for you to see the UI updated in response to that action. For instance if you remove a VM in the webadmin and click the ok button in the UI, the grid will still show the VM until the next refresh cycle, not when the VM is actually removed. I have created a wiki page that outlines the issues, and the ways we are intending to solve these issues [1]. Feel free to comment/e-mail/etc to let me know what you guys think.

Obviously we wouldn't do 100 round trips for the image, we would generate a single image sprite that would contain all the images in a single request and display the appropriate part of the image in the grid. You are right in general front-end logic is not done on the back-end. However we must consider if we are really doing front end logic here, or if we are just displaying some reporting information as part of the grid. If we are not storing the statistics anywhere, then this is a terrible plan, and we should do the logic on the client, but if we are, it is something to consider. > > > == From L&F point of view == > > > - would look pretty much like the one proposed by Malini: > > > http://style.org/chartapi/sparklines/ > > > > > > == From data point of view == > > > - do not do any averages on VDSM side (since it already does them for > > > CPU > > > and network and the memory is stable enough) - do not do any averages on > > > engine side (since would have to be done for each FE separately and > > > stored > > > in session which is

Before this optimization we already had code calling runMultiple(Query/Action) and we will have to figure something out for the REST API there as well.

Re: [Engine-devel] Java Newbie: Renaming some functions to fix findbugs warnings
Adam, We are aware of this issue and we actually have a patch somewhat ready to solve the issue [1]. We made the RunQuery/RunAction/etc method deprecated to encourage people to no longer use them. We have patch ready to remove all current uses of RunQuery/RunAction/etc from the code base, but haven't gotten around to rebasing/merging the patch.

Hi, 1. Is your engine runnning? [1] 2. Did you also start separately the debug mode [2] (This is debugging the webadmin) 3. Did you go to the right URL [3] 4.

Re: [Engine-devel] developmen environment: logs
The attached ovirt-engine.xml.in.debug should be what you are looking for. Save it as ~/ovirt-engine/share/ovirt-engine/services/ovirt-engine/ovirt- engine.xml.in (maybe backup the original first). Restart the engine and you should be running in debug mode.

Re: [Engine-devel] UI: VM list not populating
Adam, Is this just when you first login into the webadmin or whenever you go to the VM tab? In other words if you login, then switch to the templates tab and back again to the VM tab does it still not load? What about when you manually refresh the grid?

Re: [Engine-devel] Can not debug GWT with chrom
Did you compile GWT for use with Chrome? I think the standard make install-dev does not, but you can add support by setting the extra build flags like this: DEV_EXTRA_BUILD_FLAGS_GWT_DEFAULTS="-D gwt.userAgent=gecko1_8,safari" that will compile it with 2 iterations, one for firefox and one for chrome.

Re: [Engine-devel] VM Ip Address
Did the administrators install the ovirt-guest-agent on the VMs. IIRC the
engine doesn't know the IP address of the VM unless the VM tells the engine
with the guest agent.

Re: [Engine-devel] [Users] adding scripts
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.

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.

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.
