Are there open source applications that provide a set of features similar to Amazon EC2 or Rackspace Cloud? Basically, I want a tool that I can install on one or more servers that work with a virtual machine monitor, such as Xen, and allows me to create, destroy and clone virtual machines on the fly using some kind of API.
Like other posters, I would recommend Eucalyptus . It can use Xen or KVM to manage virtual machines through the same request API that Amazon EC2 provides. It also provides an S3-compatible service for storing files in codes named Walrus. If you need proof that you can run it through Xen, here from the configuration file for Eucalyptus:
# The hypervisor that the Node Controller will interact with in order # to manage virtual machines. Currently, supported values are 'kvm' # and 'xen'. HYPERVISOR="xen"
In addition to the Eucalyptus mentioned in other answers, you can also take a look at OpenStack . This is another large Amazon AWS open cloud stack. It was supported by NASA, RackSpace, Citrix, Intel, AMD and Dell, among many others.
