Re: [one-users] OpenNebula OCCI compliance: 0.8 or 1.1

[florian.feldhaus]

Hi Dirk,

OpenNebula has OCCI support for the early draft of OCCI (version 0.8)
since quite a long time. As the implementation is stable and used by quite
a few projects, it is IMHO still the default implementation in the
OpenNebula distribution. To achieve compliance with the (only) officially
released specification of OCCI (version 1.1), we created the Ecosystem
project OGF-OCCI. It has the advantages, that it can be used standalone -
and thus alongside the old OCCI implementation. If you start with a new
project based on OCCI, it is strongly recommended, that you use the OCCI
1.1 implementation. More information on the implementation can be found
here:
dev.opennebula.org/projects/ogf-occi/wiki/

OCCI 1.1 has a lot improvements regarding the REST interface and the
representation of resources. OCCI 0.8 was based on XML whereas OCCI 1.1
allows different renderings of the interface (HTTP headers only, plain
text, soon (currently only a draft) JSON and XML).

If you have questions regarding the OGF-OCCI implementation, feel free to
join the Ecosystem Mailinglist and discuss your problems / ideas with us
there!
http://lists.opennebula.org/listinfo.cgi/ecosystem-opennebula.org

For questions regarding the OCCI specification please send a mail to the
OCCI mailinglist:
http://occi-wg.org/community/contribute-communicate/

Best regards,
Florian

Re: [one-users] Passenger + OpenNebula index.html is not found

[florian.feldhaus]

Hi Stefano,

the problem is probably, that you start passenger in the wrong directory. If 
you unpacked the zip file, you have to change to the ogf-occi folder and start 
passenger there.

Also, we did a lot of code improvements and bug fixes since version 0.3 and 
will release a new version as soon as some remaining bugs are fixed. If you 
want to use the latest version you can check it out using
git clone git://git.opennebula.org/ogf-occi.git

Cheers,
Florian

Betreff: [one-users] Passenger + OpenNebula index.html is not found

Cheers,

I'm using OGF-OCCI 0.3_beta2 and OpenNebula 0.3_beta2 on Ubuntu 10.04 32-bit. I 
successfully installed and started it but I'm getting this:

2011/11/07 09:56:29 [error] 1262#0: *4 "/home/ste/public/index.html" is not 
found (2: No such file or directory), client: 127.0.0.1, server: _, request: 
"HEAD / HTTP/1.1", host: "0.0.0.0"

at every passenger startup and this:

2011/11/07 10:11:12 [error] 1262#0: *19 "/home/ste/public/-/index.html" is not 
found (2: No such file or directory), client: 192.168.23.254, server: _, 
request: "GET /-/ HTTP/1.0", host: "192.168.23.3:3000"

for every request I send (-, compute, storage, network). I cannot GET or POST 
anything as it always tells me "index.html is not found".

Manually creating those folders doesn't help.

All that the logfile contains are the lines above.

Any ideas?

Thank you

Re: [one-users] OCCI 3 Requests

[florian.feldhaus]

Hi Amine,

The GET commands you are issuing are returning a HTTP return code 200 OK. It 
will return nothing, if you didn't successfully create a network, storage or 
compute object before. Regarding the POST: If you are using OCCI v0.3, then you 
should use the attribute as described here:
http://dev.opennebula.org/projects/ogf-occi/wiki/Occi_03

The virtualnetwork mixin was necessary for OpenNebula 2.2 but we decided to not 
support OpenNebula 2.2 anymore as it is missing some important features (like 
VLAN) for successfully mapping OCCI attributes. Thus, please use OpenNebula 3.0 
together with OCCI v0.3 and then creating networks shouldn't be a problem.

Cheers,
Florian

[one-users] Cloud Interoperability events

[florian.feldhaus]

The 3rd Cloud Plugfest organised by SNIA (Storage Networking Industry
Association) will take place from September 18-22, 2011 [1]. The purpose
of the Cloud Plugfest is for vendors to bring their implementations of the
Cloud Data Management Interface (CDMI) [2] and the Open Cloud Computing
Interface (OCCI) [3] to test, identify, and fix bugs in a collaborative
setting with the goal of providing a forum where interoperable products
can be developed.

To make the Plugfest more attractive for european participants, it will
take place in two locations simultaneously for the first time. Once in
Santa Clara, US (colocated with the Storage Developer Conference), and
once in Düsseldorf, Germany (see [1] for more information). A remote
participation is also possible.

Note: To register for attending at the Düsseldorf location you need to
fill the "Cloud Plugfest Planning Survey" [4]. The Plugfest
Confidentiality Agreement [5] may be signed in advance or on arrival at
the Plugfest location and will allow companies to bring unreleased code to
the Plugfest.

My colleagues and I will attend at the Düsseldorf location and we will
implement, test and demonstrate our OCCI server in combination with
OpenNebula 3.0. There will also be a very early implementation of CDMI for
OpenNebula.

Everyone interested in discussing the future of the OCCI standard is
welcome to attend OGF 33 from September 19-23, 2011. The sessions of the
OCCI WG will take place on wednesday 21st and will soon be announced in
the official schedule on the OGF website [6].

With the Open World Forum another event takes place simultaneously
(September 22-24). There will be sessions on interoperability and on the
status of current cloud projects - including OpenNebula [7].

I'm looking forward to seeing you at one of those events!

Cheers,
Florian

Re: [one-users] OCCI Server 0.3

[florian.feldhaus]

Ah, this is a problem between ruby and some operating systems. Some OS are case 
sensitive for ruby requires and others aren't. Unfortunately, I seem to have 
packaged the v0.3 packages with an OpenNebula folder containing uppercase 
letters. This is probably the cause of your problem. Please rename the folder 
lib/OpenNebula to lib/opennebula and tell me if this solved your problem.

Hi,



it looks like you successfully installed passenger. You should issue the

passenger command within the OGF OCCI folder. If you just start passenger,

it does not know, which files to serve and thus the error.



Please follow these steps (from the OGF OCCI Wiki):

3.) Download ogf-occi-0.3_beta2.tar.bz2 or ogf-occi-0.3_beta2.zip from

http://dev.opennebula.org/projects/ogf-occi/files

4.) Untar / unzip the file



5.) Change to the folder ogf-occi

6.) Change the configuration in etc/occi-server.conf

7.) Run the OCCI server with

passenger start



Cheers,

Florian

Re: [one-users] Actions Implementation On OGF- OCCI v0.2

With v0.3beta2 actions should be working. Some actions, especially for
storage are still problematic or unimplemented (e.g. snapshot or resize)
as they are not directly compatible with the OpenNebula way. Start and
Stop for VMs should be working without problems.

There have been a few problems which have been fixed in the latest beta.
Could you please test with the latest version and then report any problems
including the passenger log file?

> Has any one an information about the state of the art of the 0.2 version

Version 0.2 shouldn't be used anymore. We released the code early and made
many improvements until now and also v0.2 was only tested agains early
versions of OpenNebula 3.0.

> When OpenNebula 3.0 is planned to be launched as stable along with the v

We currently plan to release a stable version of OGF OCCI alongside or
shortly after OpenNebula 3.0. Thus, the ETA of OGF OCCI is end of
september.

> Will there be an express edition as it is the case with version 2.2 ?

We are in the progress of creating a ruby gem which will make the
installation as simple as issuing:
gem install ogf-occi

The CDMI integration is still in a very early stage, but we will
demonstrate a first version at the next SNIA Cloud Plugfest
(http://www.snia.org/cloud/cloudplugfest).

I can't comment on the embedded OCCI and as far as I know, it will not be
developed further and hopefully, the OGF OCCI will replace it soon.

The authentication is still an experimental feature. I was waiting on the
OpenNebula developers to introduce ACLs before we put further effort in
this feature. It is on my list for the next weeks to combine OCCI with
Apache authorization modules as well as OpenNebula ACLs. The goal is, to
use Apache for all the authentication handling (e.g. using Shibboleth,
OpenID, Certificates or username/password) and map or create OpenNebula
ACLs accordingly.

Regarding your problems with the listing, could you please send me the
logfile of passenger which should be located in the log folder inside the
OGF OCCI folder. Besides, I found some problems when using the Dummy
Backend with v0.3beta2 which will be fixed in the next beta soon to be
released.

We plan to publish a first release candidate before the next SNIA Cloud
Plugfest which takes place from 18.-22.9. I'd like to encourage everyone
interested in using the OCCI server or developing OCCI clients to join the
Plugfest. Attendance can be physically in Santa Clara (USA) and probably
in Düsseldorf (Germany) as well as remotely via chat and telephone.
Further information can be found here:

Re: [one-users] OCCI Server 0.3

[florian.feldhaus]

Hi Amine,

sorry for not answering your mails earlier, but I'm just back from vacation. 
Regarding your problem with OCCI Server 0.3 you should have installed passenger 
using
gem install passenger
If the passenger executable is not globally installed, please check the 
official passenger installation guide to see how you need to install it in your 
setup. The passenger documentation may be found here:

Re: [one-users] OpenNebula OCCI 1.1

[florian.feldhaus]

Hi Amine,

this may be the problem. Please try if removing the additional ruby from 
install.sh – the result should look like:
mv -f $RUBY_LOCATION/cloud/occi $RUBY_LOCATION/cloud/occi.orig

After reinstalling OCCI, please try starting the OCCI server again. With the 
next version we will get rid of these installation issues and allow to install 
OCCI standalone (it will include all necessary OpenNebula libraries).

Re: [one-users] OpenNebula OCCI 1.1

[florian.feldhaus]

Hi Amine,

there have been a few issues with OCCI 1.1 for OpenNebula v0.2. We fixed a
lot of them and plan to release a new version (0.3) in the next week. If
you can wait, I would very much recommend you to try out the next version
as soon as it is released. If you're interested, I would be glad to
provide a "beta" version to you for testing.

A few comments to your problem inline:

I haven't tested OCCI 1.1 for OpenNebula with OpenNebula Express, but
there should be no reason why this does not work.

The config files look OK.

This is strange. Maybe there are leftovers from the old OCCI server
included in the OpenNebula distribution. If you correctly installed OCCI
1.1 for OpenNebula, it should have moved away the old OCCI Server. Could
you please check (e.g. use diff or check the content of the files with
less) if the files from the ogf-occi-0.2.zip file have been installed to:
/usr/bin (e.g. occi-server)
/etc/one (e.g. occi-one.conf and occi-server.conf)
/usr/lib/one/ruby/cloud/occi (all the library files like StateMachine.rb,
CategoryRegistry.rb, ...)

Is the log output from /var/log/one/occi-server.log ?

This will probably not work. occi-compute is a script from the old OCCI
implementation and it is based on OCCI 1.1 which has a considerably
different interface specification.

Re: [one-users] Does OpenNebula work or replace VMware vCenter?

[florian.feldhaus]

Hi Derrick,

from my past experience I can say, that OpenNebula in the current version is 
not ready to replace VMware vCenter. But, with OpenNebula 3.0 many of the 
missing features are implemented and as far as I could test them, OpenNebula 
seems to be a good / cost efficient choice to replace vCenter. Integrating 
OpenNebula with vCenter and usage of ESX is possible, but from my point of view 
this is only valid as a migration path to replace it with a KVM or XEN 
infrastructure.

If you have a production setup where a downtime of your service costs a lot of 
money, then you're probably better off with vCenter and buying all their 
licenses. If you want to provide a cheap IaaS plattform, then OpenNebula 3.0 
could be right for you. BTW: From a recent comparison of OpenNebula 3.0 and the 
current version of OpenStack I got the impression that OpenNebula will be 
better suitable for IaaS environments. Especially the Sunstone Webinterface has 
more potential than the OpenStack webinterface.

Cheers,
Florian

Betreff: [one-users] Does OpenNebula work or replace VMware vCenter?

Hi guys,

My institute is running a cloud platform which is VMware vSphere based with its 
Enterprise Plus license. We also have a vCenter server for managing the 
platform.

I have been seeking a way to allow me to automate the VM deployment process and 
contextualize the Linux VMs.

OpenNebula seems to be a solution. I have read through some documentations as 
well as the VMware Driver Addon guide. But I still not quite understand many 
basic aspects of OpenNebula, particularly:

1) What's the position for OpenNebula in a VMware based platform that vCenter 
already exists?
2) Our Enterprise Plus license gives us full features of the vSphere platform, 
work with the vCenter, does OpenNebula interact with those features as well?

I'd keen to hear from anyone who has the experience on this.

Thanks in advance.
Derrick

Hm. That gives us more hints, but unfortunately I don't understand
OpenNebula deep enough to be able to debug the problem from the segfault.
Best idea would be to try out the newer version of OpenNebula (e.g. 2.2)
and see if the problem has been fixed there... Otherwise, you need to wait
for feedback from the OpenNebula team.

Re: [one-users] oned keeps dying without a trace (2.0.1)

[florian.feldhaus]

Hi Carsten,

have you had a look at your system logs (e.g. /var/log/messages)? Are there any 
suspicious problems? Debugging such a behaviour is really hard and often occurs 
due to some other problem (e.g. stale NFS, SSH problems, high load due to 
nightly backup tasks, etc.).

It might help if you try to find the time when OpenNebula dies and search for 
events in the system logfiles and in the cron jobs (e.g. /etc/crontab 
/etc/cron.d /etc/cron.daily).

This often happens in the middle of the night, so I don’t think it is due to

Re: [one-users] OCCI v 1.1

[florian.feldhaus]

Damn. The links to the files have changed since I wrote them into the Wiki. I 
searched for a Redmine machanism to dynamicly link to the files, but that's not 
yet supported by Redmine. So I changed the text to point to 
http://dev.opennebula.org/projects/ogf-occi/files and now one more click is 
required to download the file.

BTW: We are currently working on a big update for the OCCI 1.1 server based on 
the feedback we received during the last weeks. With the next version we will 
use Phusion Passenger to support either a standalone ruby webserver, Nginx or 
Apache. This improves authentication (e.g.all Apache/Nginx Auth modules like 
Shibboleth, OpenID, etc. should become available) and scalability a lot. Also 
we are using the new template mechanism of OpenNebula 2.4 to add more OCCI 
functionality (e.g. OS templates, full OCCI action support).

Cheers,
Florian

[one-users] OCCI for OpenNebula

[florian.feldhaus]

Hi,

recently we announced a new ecosystem project for OpenNebula
(http://blog.opennebula.org/?p=1596). This project brings OCCI 1.1 support
for OpenNebula and will focus on interoperability between different OCCI
implementations. The OCCI implementation is more or less complete and the
OpenNebula integration is usable, but still in an early stage.


More information on the project can be found here:
http://dev.opennebula.org/projects/ogf-occi/wiki

For questions regarding the OCCI for OpenNebula project please use the
OpenNebula ecosystem mailinglist
(http://lists.opennebula.org/listinfo.cgi/ecosystem-opennebula.org).

Cheers,
Florian

Hi Zeeshan,

work is already in progress regarding OVF and OCCI. For more information
ask on the OCCI WG Mailinglist.

Re: [one-users] OCCI version

[florian.feldhaus]

Hello Zeeshan,

in OpenNebula currently only version 1.0 is supported, but we started
development for OCCI 1.1. An official announcement of the project as
OpenNebula Ecosystem project is planned for next week. We still need to
tidy up a bit and add some usage notes.

The Sourcecode can be found at:
http://dev.opennebula.org/projects/ogf-occi/repository

Until further notice, the sourcecode is still considered experimental!

Cheers,
Florian

Re: [one-users] OFG-OCCI usage example

[florian.feldhaus]

Hi Justin,

the OGF-OCCI project is currently under heavy development and the
OpenNebula integration is still in a pre alpha phase. I want to finnish
the initial documentation / usage manual until next monday. Until then you
can try to use the server using a REST client [1] and specify requests
according to the OCCI 1.1 HTTP Rendering document [2]. By default, the
OCCI server uses a dummy backend instead of the OpenNebula backend. If you
want to experiment, you can change this in etc/occi-server.conf. The dummy
backend is stable (consider it in a beta status), but the OpenNebula
backend needs some work which we want to finnish over the weekend. On
monday we will release a first (Alpha) version of the OCCI 1.1 server for
OpenNebula.

Cheers,
Florian

Re: [one-users] sharing ubuntu contextualized VM ?

[florian.feldhaus]

Hi!

You should NEVER use a Virtual Machine from a person you do not really
know. You could never know how it is configured and if there are security
problems. We recently had a security incident in the Grid where someone
ran a virtual machine just for testing which he got from someone else.
Unfortunately the machine only had a really weak password and was used to
break into the local network...

Better use a kickstart or preseed file and create your own machine. To
create a kickstart file, you can use system-config-kickstart or adapt the
following kickstart to your needs. The password can be created with
openssl passwd -1 -salt "NaCl" "don't use this"

Re: [one-users] OCCI question

[florian.feldhaus]

Hi,

currently OpenNebula only supports OCCI 1.0. Support for OCCI 1.1 is under
development and a first version will be released soon (probably next
week). As far as I know there is currently no developer guide for OCCI in
OpenNebula but it would be a good idea to create one. As soon as the new
version is public I would like to help writing such a guide.

Cheers,
Florian
