I am looking at turning my old Dell 2650 and 2950 servers into Vmware vSphere Servers, however vSphere is very very expensive.

Is there an open source alternative that provides the same performance as vSphere in a Ubuntu or Debian distro? I dont actually mean "Virtual box" or "Vmware player" but rather a server hypervisor that is easy to set up and host virtual machines on my network?

Best of all you can run your OpenStack on Ubuntu without a hitch - it is Linux agnostic.

Intel recently migrated 17,000 virtual machines from VMware to OpenStack and reduced provisioning time from 90 days to 30 minutes while saving over $21 million in licensing (and counting). Download the white paper written by Intel engineers at
