VirtuaLinux is a Linux meta-distribution that allows the creation, deployment and administration of both physical and virtualized clusters with no single point of failure. VirtuaLinux supports the creation and management of virtual clusters in seamless way: VirtuaLinux Virtual Cluster Manager enables the system administrator to create, save, restore Xen-based virtual clusters, and to map and dynamically remap them onto the nodes of the physical cluster. We introduces and discuss VirtuaLinux virtualization architecture, features, and tools. These rely on a novel disk abstraction layer, which enables the fast, space-efficient, dynamic creation of virtual clusters composed of fully independent complete virtual machines.
