This machine will act as the OpenNebula server and therefore needs to have installed the following software:

• ruby >= 1.8.5
• sqlite3 >= 3.5.2
• sqlite3-dev >= 3.5.6-3
• sqlite3-ruby
• libxmlrpc-c >= 1.06
• scons >= 0.97
• g++ >= 4

These packages are only needed if you want to rebuild template parsers:

• flex >= 2.5
• bison >= 2.3

Most of this software is already packaged in linux distributions. Here are the packages needed in a debian lenny.

• ruby: ruby
• sqlite3: libsqlite3-0, sqlite3
• sqlite3-dev : libsqlite3-dev
• sqlite3-ruby: libsqlite3-ruby
• libxmlrpc-c: libxmlrpc-c3-dev, libxmlrpc-c3
• scons: scons

Provisioning hosts need to have installed:

• ruby >= 1.8.5
• sudo >= 1.6.9

And, depending on the chosen hypervisor, please check the virtualization section of the Configuration Guide for additional requirements.

Not known issues.

The xen packages on Lenny seems to be broken, and they don't work with the tap:aio interface

Sander Klous in the mailing proposes the following workaround:

<xterm> # ln -s /usr/lib/xen-3.2-1/bin/tapdisk /usr/sbin # echo xenblktap » /etc/modules # reboot </xterm>

When installing libxmlrpc you have to specify that it will be compiled with thread support:

# USE="threads" emerge xmlrpc-c

Centos does not come with needed versions of following packages:

• scons
• xmlrpc-c
• sqlite

Here are the instructions on how to install them.

The version that comes with Centos is 0.96 and it is not compatible with our build scripts. To install version 0.98 you can download the RPM at:

http://www.scons.org/download.php

Tested with scons-0.98.5-1.noarch.rpm.

To install xmlrpc-c there is an apt repository with needed packages. You can create a new file in /etc/apt/sources.list.d containing this line:

repomd http://centos.karan.org el5/extras/testing/i386/RPMS

After that you need to update apt database and install these two packages:

$ apt-get install xmlrpc-c xmlrpc-c-devel

This package should be installed from source, you can download the tar.gz from http://www.sqlite.org/download.html. It was tested with sqlite 3.5.9.

If you do not install it to a system wide location (/usr or /usr/local) you need to add LD_LIBRARY_PATH and tell scons where to find the files:

$ scons sqlite=<path where you installed sqlite>

Follow these simple steps to install the OpenNebula software:

• Download and untar the OpenNebula tarball.
• Change to the created folder and run scons to compile OpenNebula

scons OPTION=VALUE

the argument expression [OPTIONAL] is used to set non-default paths for :

• OpenNebula can be installed in two modes: system-wide, or in self-contained directory. In either case, you do not need to run OpenNebula as root. These options can be specified when running the install script:

./install.sh <install_options>

where <install_options> can be one or more of:

Now you need to configure OpenNebula to adjust it to your particular cluster.

Depending on the installation mode (defined by the presence or absence of the -d option in the installation script), there are two possibilities with respect to the layout of the OpenNebula files.

Once the OpenNebula software is installed specifying a directory with the -d option, the next tree should be found under $ONE_LOCATION:

Once the OpenNebula software is installed without specifying a directory with the -d option, the next tree reflects the files installed:

To verify the installation, we recommend to follow the steps in the QuickStart guide, from this step onwards. Before tacking it, please make sure that your environment is correctly set.
