  - arping (part of iputils package)

    ftp://ftp.inr.ac.ru/ip-routing/iputils-current.tar.gz

  - mdadm (Linux Software Raid tools)

  - Python OpenSSL bindings

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

Installation of the software

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

To install, simply do ``./configure --localstatedir=/var && make && make install``

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

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

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

More details about the installation process are in the docs/installing.pdf file.

Cluster initialisation

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

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

directories:

  - /etc/ganeti

  - /var/log/ganeti

  - /var/lib/ganeti

  - /srv/ganeti and /srv/ganeti/os

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