Dedoimedo published a review and tutorial on the Xen Cloud Platform (XCP)

We had an introduction article on Xen and we discussed the Xen live CD. Now, let us explore another Xen-based product. Xen Cloud Platform (XCP) is a standalone virtualization software, similar to VMware ESXi. XCP delivers the Xen Hypervisor with support for a range of guest operating systems, including Windows and Linux network and storage support, and management tools in a single, tested installable image.

XCP is based on Citrix XenServer, which we will review next week. For now, let's focus on the Cloud Platform and see what it can give us. XCP requires a dedicated host for installation; in other words, it does not run out of the context of another operating system, it has its own minimal kernel and a basic console for management. The product is free and open-source and therefore a worthy candidate for considering as a part in your virtualization arsenal.
