VirtCloud is a system for interconnecting virtual clusters in a state-wide network based on advanced features available in academic networks. The system supports dynamic creation of virtual clusters without the need of run-time administrative privileges on the backbone core network, encapsulation of the clusters, controlled access to external sources for cluster hosts, full user access to the clusters, and optional publishing of the clusters. A prototype implementation has been deployed in MetaCenter (Czech national Grid infrastructure) using Czech national research network CESNET2.
