Comment OpenNebula != free (Score 1) 87
OpenNebula is still pitched as a commercial service even if it runs some open source tools and provides a community edition. The community edition likely requires people to pay for their own cloud / private backend to provide VMs. In subscription form it might still be significantly cheaper than VMWare which is a major incentive but the "we're using open source" angle probably isn't what convinces people to try it.
