For testing, you also need the YAML module for Python (http://pyyaml.org/).

For building from source, you also need tar, gzip or bzip2 and make.

Installation of the software

============================

To install, simply do ``./configure --localstatedir=/var --sysconfdir=/etc && \

make && make install``

This will install the software under /usr/local. You then need to copy

ganeti.init to /etc/init.d/ganeti and integrate it into your boot sequence

(``chkconfig``, ``update-rc.d``, etc.).

Cluster initialisation

======================

Before initialising the cluster, on each node you need to create the following

directories:

  - /etc/ganeti

  - /srv/ganeti, /srv/ganeti/os, /srv/ganeti/export

After this, use ``gnt-cluster init``.
