Microsoft Hyper-V Server 2008 R2 has the capability to take advantage of greater computing resources compared with the company's first version. For e.g., with R2, Microsoft increased the number of physical processors supported from four to eight. The delta on logical processors is even more dramatic. While the original Hyper-V supported up to 16 logical processors, the new version can handle up to 64. Physical memory support also takes a huge leap -- from a 32GB capacity to a 1TB limit. Supported guest operating systems include Windows Server 2008, Windows Server 2003, Windows Server 2000, SuSE Linux Enterprise Server 10 or 11 and Red Hat Enterprise Linux 5.2 and 5.3. Supported client operating systems are Windows 7, Windows Vista and Windows XP.
