What is Virtual Machine Manager?:
The clue is in the name, but Virtual Machine Manager (VMM) is a management system for virtual machines (VM’s)..however, and this is the ace up Microsoft’s sleeve…it also manages physical servers-this is in contrast to VMWare’s VirtualCenter as that can only manage VM’s. That means IT Administrators only need to learn to use one console to manage ALL their servers and anything that makes an Admin’s job easier is a good thing yes? 🙂
Microsoft Virtual Machine Manager delivers end to end support for consolidating physical servers onto virtual, fast Physical to Virtual (P2V) conversion “Intelligent Placement” of server workloads to balance performance and of course, the centralized console.
It also contains V2V conversion, making it easy to convert any existing VMWare VMDX/VMX files to Microsoft’s VHD format.

What’s new in VMM 2008?:
Good question! VMM 2008 is packed full of great new features including:
· Allows for fault tolerant and cluster aware VM’s to be created
· Integration with VMWare’s Virtual Center
· Windows PowerShell scripts for automation etc supported across multiple platforms
· Performance and Resource Optimization (PRO) is a feature of VMM that can dynamically respond to failure scenarios or poorly configured components identified in hardware, operating systems, or applications
· Working through PRO-enabled Management Packs together with System Center Operations Manager 2007’s, PRO can either alert an administrator of an unhealthy system or application state and its proposed recommended corrective action or it can respond by automatically creating a system that is responsive and self-healing. PRO features are available to ESX VM’s as well.
· VMM 2008 is now fully cluster-aware, meaning that it can detect and manage Hyper-V host clusters as a single unit
· New in this version of VMM is automatic detection of virtual hosts that are added or removed from the cluster—thus easing the burden on the administrator to manage this function
· Creating a High Availability (HA) VM is a simple as selecting a tick box
· VMM 2008 also supports VMware host clusters in which the nodes of the cluster are VMware ESX Servers
