NASA Nebula Ubuntu cloud

According to The Register NASA have started to build a private Nebula Cloud based on Ubuntu 10 and Eucalyptus Enterprise 2 which will likely underpin websites across the federal government.

Eucalyptus Enterprise works with the Xen and KVM hypervisors and the latest version has now been ported to VMware hypervisors as well, allowing for installation atop VMware's vSphere, ESXi, and ESX virtualization technologies. The Eucalyptus Enterprise edition also includes an image converter that helps users develop VMware-based applications that are compatible with Amazon EC2.
