[one-users] Prerequisite Concern about OpenNebula!

[Tino Vazquez]

Dear Sok,

In order to install OpenNebula you just need servers connected with an
ethernet network, not some cluster middleware. OpenNebula is an
infrastructure tool, so you need to have (or acquire) infrastructure
knowledge in order to correctly use it.

Almost all the answers to your questions are detailed in the
documentation, please read carefully [1] where all the requirements to
install opennebula are mentioned. If after reading there are still
unclear concepts or terminology, please come back and we will do our
best to clarify them. Be aware that we can provide support for
OpenNebula, but we will delegate questions about surrounding
technologies (KVM, Linux distros, etc) to the folks responsible, since
they are much better prepare to answer them.

Regards,

-Tino
