Openstack — Ovirt
Assess your scale, team skill level, and required features. If you don’t need multi-tenant IaaS or advanced SDN, start with oVirt. If you are building a cloud to rival AWS on-premises, go with OpenStack. For gradual migration or hybrid management, explore the Nova-oVirt driver integration.
For most organizations starting with open-source virtualization, oVirt provides a gentle on-ramp. As needs for multi-tenancy, granular API control, and scale grow, OpenStack becomes the natural evolution. In specific hybrid scenarios, running OpenStack on top of oVirt offers the best of both worlds – robust VM management with cloud-native APIs. ovirt openstack
