With Windows Server 2012 Hyper-V, it is now easier than ever for organizations to take advantage of the cost savings of virtualization and make the optimum use of server hardware investments by consolidating multiple server roles as separate virtual machines. You can use Hyper-V to efficiently run multiple operating systems — Microsoft Windows, Linux, and others — in parallel, on a single server. Windows Server 2012 extends this with more features, greater scalability and built-in reliability mechanisms.
