Is there a way to run Ulteo OVD in the Amazon EC2 cloud?

The new ubuntu 9;.04 does seem to support Amazon cloud images. I am not sure
whether this is possible but wanted to hear your thoughts.

One of the issues with Ulteo OVD is a scalabe server. Can such a service
like Amazon EC2 used to scale up requirements on the hardware side.

Thanks,
Prabhu

Here is what i got from the Jaunty jackalope features

Ubuntu 9.04 Server Edition makes it easy to experiment with cloud computing.
Eucalyptus <http://eucalyptus.cs.ucsb.edu/>, an open source technology which
is included in Ubuntu as a technology preview, enables you to use your own
servers to deploy, experiment and test your own private cloud that matches
the Amazon EC2 API. You can dynamically create virtual machines, configure
multiple clusters into a single Cloud and even provide an EBS (elastic block
storage) equivalent and an S3 compatible storage manager.

Hi,

we haven't try for the OVD but it should be possible.

We tried more than one year ago for deploying the Online Desktop
infrastructure but it was catastophic in term of performance and network
latency, but I'm sure it improved since that.

If you try please let us know about the results!

Regards

	Ga?l.

Hi Ga?l,

I'm trying to instal OVD on a Ubuntu 8.04 LTS AMI on EC2 (Eric Hammond's AMI 
to be exact) and I'm running into some problems.


I'm following this page's documentation for installation 
http://www.ulteo.com/home/ovdi/openvirtualdesktop/documentation/installation?autolang=en
and most things seem to go fine. LAMP is installed. The session manager is 
installed fine. I go to http://URL/sessionmanager/admin and set the MySQL 
settings and everything seems to be fine.

The application server installation also goes fine, until I need to restart 
the server with


/etc/init.d/ulteo-ovd restart
* Re-starting ulteo-ovdd daemon 
   * Stopping ulteo-ovd daemon... 
      * Stopping OpenBSD Secure Shell server... 
[ OK ]
* Stopping portmap daemon...                                            [ OK ]
* Stopping system message bus dbus                                      [ OK ]
* Stopping periodic command scheduler crond                             [fail]
* Stopping Common Unix Printing System: cupsd                           [ OK ]
                                                                         [ OK ]
* Starting ulteo-ovd daemon... 
   * Starting OpenBSD Secure Shell server...                               [ OK ]
* Starting portmap daemon...                                            [ OK ]
* Starting system message bus dbus


And that's it. It doesn't proceed afterwards. I'm assuming that bus and dbus 
don't exist under Xen.

Is restarting these services necessary for OVD usage? How can I modify the 
/etc/init.d/ulteo-ovd restart script to comment out starting these services? 
Any hint would be greatly appreciated.

Im really excited about running OVD on EC2. I think it holds lots of potential 
for my clients, and is another step in SaaS.

Cheers

I'm adding our devel team in CC:, I think they can have some
ideas/suggestions for you. Anyway, maybe that's the Ubuntu 8.04 VM that
your are using that is uncomplete. I remember I ran into such troubles
when I implemented OD1 on EC2 some time ago, and I had to find a better
Linux image.

Absolutely, you are likely to run into latency troubles though, which is
key when speaking of remote display-based systems.

Keep us updated!

Thanks Ga?l. All I need to know is how to modify the /etc/init.d/ulteo-ovd to 
not start dbus and bus, and if OVD actually can work without them.

The images I'm using are the alestic images http://alestic.com/ They are 
pretty much considered the standard Ubuntu images, and are widely used by EC2 
users and pretty well maintained with an active community.

I'm actually surprisingly finding EC2 suitable for even real-time 
applications. People are happily using it for Asterisk now, for a production 
environment, so it will be interesting to see how something like Ulteo OVD 
runs on it.

> Keep us updated!

Thanks. I will

To deactivate dbus go on file "/opt/ulteo/etc/init.d/ulteo-ovdd" line 71 
, comment "$DBUSJAIL /etc/init.d/dbus start || true"

OVD will work without dbus but user applications might not fully working 
(depend if they need dbus)

Merci Laurent.

Using your instructions I had to comment out starting dbus and cups.
After this, the ulteo-ovd service started just fine.  I followed the
instructions for registering the server using the backend interface and
also defined users and groups and finally, used the publication wizard
to make the required applications available.

After logging in as a normal user and trying to start the session, the
OVD window opens in Firefox, the JRE is loaded, and it seems like
everything is working fine, but it then just hangs in there and does
nothing. Only the very top of the desktop, which has the "Share Desktop"
button is available, the rest of the page is blank.

Any suggestions on this? Is it related to the disabling of dbus?

Cheers

It maybe rather be related to a Java issue.

Can you start a session and report the content of the java console?
