OpenNebula

From the OpenNebula documentation:

"OpenNebula offers a simple but feature-rich and flexible solution to build and manage enterprise clouds and virtualized data centers. OpenNebula is designed to be simple. Simple to install, update and operate by the admins, and simple to use by end users. Being focused on simplicity, we integrate with existing technologies whenever possible. You’ll see that OpenNebula works with MySQL, Ceph, LVM, GlusterFS, Open vSwitch, Ceph, LDAP... This allows us to deliver a light, flexible and robust cloud manager."

CONFIGURING XEN PROJECT

The configuration of the hypervisor for use with OpenNebula is unremarkable. OpenNebula does not make unusual demands on the hypervisor configuration. Items of note:

• According to the release 4.8 documentation, OpenNebula uses the deprecated "xm" toolset.
• According to the documentation, it is suggested to use SCSI devices on HVM to avoid the limits of the number of IDE drives support.
