 | Automated Virtual Machine Creation with On-Demand Software Installation |
The idea behind cloud computing is to deliver Infrastructure-,

Platform- and Software-as-a-Service (IaaS, PaaS and SaaS) over the Internet
on an easy pay-per-use business model. In this chapter, we present
our work and experiences in building a private cloud. In our work, we
create virtual machines (VMs) by choosing a base image, and post installing
software packages selected by the user on the fly. This approach
gives high flexibility, saves disk space, guarantees installation of newest
software versions, and enables monitoring of the installation progress. In
addition, we extend the basic monitoring abilities of OpenNebula, a virtual
infrastructure manager, by collecting historical data about hosts and
VMs and enables the monitoring to be integrated into Nagios, an IT infrastructure
monitoring tool.
