From your understanding of the Xen approach to virtualization, discuss specific features of Xen that can support the XenoServer architecture, thus illustrating the synergy between virtualization and cloud computing.

What will be an ideal response?

The XenoServer architecture supports the discovery and use of XenoServers or indeed more sophisticated servers or cluster of servers with a given level of connectivity. The architecture therefore promotes a view of everything as a service as in cloud computing. Through using Xen, the mapping of XenoServers to physical hardware can be managed. More generally, the use of virtualization in cloud computing supports the provision of infrastructure as a service by providing access to virtual rather than physical machines.
