[one-ecosystem] Which cloud interface to choose

Mon Jan 9 00:48:55 PST 2012

Hi John,

sorry for answering this late, but during christmas/new year, time was too restricted to answer all my mails.

If you still have the problem, could you please send me the logfile of the server? It's located in ogf-occi/log/passenger.3000.log

Cheers,
Florian

Well, I think, now, I use the latest version of OCCI Server (I had configured incorrectly the server, and the old version was running…)

Although I deal with some problems:

When I run getComputes with URI http://ddd.dd.dd.ddd:4567/compute/
server respond with code=200 but response.content.length=0
When I run stopCompute with HttpUtils .post(URI, …)  and URI= http:// ddd.dd.dd.ddd:4567/compute/536?action=stop
server respond with code=400
When I run deleteCompute with HttpUtils.delete( ID ) and ID= http:// ddd.dd.dd.ddd:4567/compute/536
server respond with code=404

I can’t figure out what is going wrong!

thanks a lot!
John

Hi John,

I'm developing the OCCI 1.1 interface for OpenNebula, see the Wiki at
http://dev.opennebula.org/projects/ogf-occi/wiki/
for more information.

You are probably using the old implementation included in OpenNebula based on the not officially released OCCI 0.8. I can't really help you with that. If you want to try out the new implementation, just follow the steps in the Wiki I mentioned above.

Cheers,
Florian

Hi!

Florian thanks a lot for your valuable info. I have study your implementation
and I think you have done a very good job! The source code help me
to understand how to develop my web application.

Currently I am trying to list the VMs using the OcciOneListTester but I receive
the message “Basic auth not provided”.

I believe, I have configure correctly the occi service since I can list the VMs
using the command occi-compute.

I use OpenNebula 3.0

I search for a solution but the url I found http://comments.gmane.org/gmane.comp.distributed.opennebula.user/4323
didn’t help me to understand what I have to do.

thanks a lot
John

We are currently doing exactly the same using OCCI (for IaaS management) and CDMI (for storage). I summed it up in a screencast which you may find here:
dl.dropbox.com/u/4837292/OCCI_CDMI_Screencast_large.mp4

If that's what you want, you can find the OCCI 1.1 server for OpenNebula here (please use the latest version from git):
http://dev.opennebula.org/projects/ogf-occi/wiki

The CDMI server can be found here:
https://github.com/livenson/vcdm/tree/master/src/vcdm

And you can find the Webclient (including a Java library which can be used stand alone) here:
https://github.com/gwdg/Pollux

Especially the client is currently not too well documented, but if you like to use it, we would be glad to improve documentation and provide support.

Cheers,
Florian

Hi

I want to make an GUI for educational purposes, in order, students, to use VM
for their projects. The GUI must have some basic functions such as start, terminate,
reboot a VM.

There are two cloud interfaces supported: EC2-Query API and OCCI-OGF.
Which of them is more appropriate for my purpose?

thanks a lot
John
