Management of your virtual servers is easier than with traditional physical servers because you will have a more centralized interface for those consolidated servers. The application that you use to manage your servers will vary based on what virtualization application you use. For example, with VMware ESX Server, you will manage your servers (ie: power status, configuration, remote control) from either the VMware Virtual Infrastructure Client (VI Client) or the VMware Infrastructure Web Access interface (via a web browser). You could also manage your ESX Server via the command line using SSH.
With Microsoft Hyper-V, you would manage your server using the Hyper-V Manager MMC.
