What Is Virtual Machine Manager?

Up to now, we have discussed what Hyper-V provides to the data center and how to deploy and configure single virtual machines. Once the organization understands and adopts the value of system virtualization, IT administrators look for improved ways to deploy, control, and administer the virtual infrastructure. Enter Microsoft System Center Virtual Machine Manager 2008. Virtual Machine Manager 2008 (VMM 2008) provides a System Center common management interface for the virtualized data center that allows increased server utilization and dynamic resource allocation. It also works across multiple virtualization platforms, including those from Microsoft and VMware. Third-party add ons for XenSource, XenWorks, and others will be available in the near future. VMM 2008 takes a holistic approach to managing the virtual infrastructure by examining and rating the virtualization hosts. It compares these hosts against a set of criteria and rates the suitability of the virtual machine (VM) to be deployed on the hosts where it can be deployed. This is important because a single physical host server can host tens of virtual machines.
