OpenNebula is considered an IaaS solution than just a VM manager. It
orchestrates image storage (NFS, SCP, etc.). It handles setting up VMs with
a virtual network environment (VLANs). It interfaces with the hypervisor to
create and control VMs. OpenNebula comes with a default scheduler for
handling placement of VMs on hosts.
It also supports contextualization in VMs such as setting up IP address, ssh
keys, etc.

You could use LibVirt directly, but then you would be missing out on the
information captured by OpenNebula information agents in the SQLite database
that you would perhaps want to display on the management interface.
