From what I have read in the release notes for VC2.5 Update 5, some of the new features above vc2.5u4 includes support for more than 35 virtual machines per host in an HA cluster, customization of Windows Server 2008 guest operating systems, and Performance Overview plug-in, which provides a single view of key performance metrics for CPU, memory, disk, and network without having to navigate through multiple charts. I am updating our VC to 2.5U5 as we are preparing for 2008 deployments at the begining of the new year.
