[one-users] Why to use Opennebula?

In our web you can read about the generic benefits of a cloud management
tool [1], the main advantages of OpenNebula [2], and a list of low-level
features [3] for the upcomming 3.0 release (currently you can test the beta
release [4]).

Is it worth to install OpenNebula? I'd say it depends on your scenario.
OpenNebula will prove useful if you need to manage more than one hypervisor,
avoiding vendor lock-in. Another big benefit is that being fully
open-source, you will be able to customize and tweak every small aspect of
you cloud.
