Extending OpenNebula with hooks
Action on the Hook
Virtualization speeds up the pace of a system administrator's life. With KVM, Xen, and VMware, admins can provision systems far more quickly than they could have procured and installed new hardware back in the days of dedicated servers. You can use the extra time for cloning image configurations, copying directories, and mounting storage resources. However, things get tricky when hardware issues mean you need to shut down, migrate, and restart virtual machines.
If you want to reduce the tedium of working with virtual machines, you could resort to an Infrastructure-as-a-Service (IaaS) cloud solution. The cloud handles the most important tasks of server virtualization, manages the basic infrastructure (e.g., DNS and DHCP), and provides a web interface. Admins can choose from a gallery of open source products, such as OpenStack [1], openQRM [2], Eucalyptus [3], or Ganeti [4], each with its specific functionality and concepts.
Because of the diversity of scenarios, most cloud stacks behave in a complex way and require a lengthy learning curve. OpenNebula [5], which originated in Spain, sets out to prove that things can happen more quickly, if your users have typical requirements.
Lean Cloud Management
OpenNebula spent its childhood in the academic field of grid computing and is now considered a lightweight enterprise solution. The Fermilab particle accelerator uses OpenNebula to manage hundreds of virtual machines, and industrial customers include Telefonica and Akamai. The main developer from C12G Labs offers commercial support and is currently establishing an international network of partners
