Apache VCL
The Apache VCL incubator project.
VCL, Virtual Computing Lab. The VCL can be many things, first and foremost it is a open-source system used to dynamically provision and broker remote access to a dedicated compute environment for an end-user. The provisioned computers are typically housed in a data center and may be physical blade servers, traditional rack mounted servers, or virtual machines. VCL can also broker access to standalone machines such as a lab computers on a university campus.
...
Also using the scheduling API it can be used to automate the provisioning of servers in a server farm or HPC cluster.

Conceptual Overview
...
- Automated provisioning, on-demand or future based
- Brokers user sessions
- Block allocations - provisioning larger number of compute environments for a specific event
- For the class room
- For a conference workshop
- Physical (bare-metal) provisioning using xCAT
- Virtual machine provisioning on VMware ESXi, VMware ESX Standard server, VMware Free Server
- Image creation - allow end-users to create custom environments
- Image revision control - create multiple revisions of an image
- Statistics of environment usage
- Privilege control - grant varying levels of control to end-users through web interface
- Image checkout, image creation, manage users, manage resources, manage resource schedules
- Set available/unavailable schedules for nodes
- Multiple Management Nodes for scalability
- API support for making requests and provisioning resources
