Virtual Machine Manager (VMM) is a management solution for the virtualized data center. You can use it to configure and manage your virtualization host, networking, and storage resources in order to create and deploy virtual machines and services to private clouds that you have created.

A deployment of VMM consists of the following.

NameDescription
VMM management serverThe computer on which the VMM service runs. It processes commands and controls communications with the VMM database, the library server, and virtual machine hosts.
VMM databaseA Microsoft SQL Server database that stores VMM configuration information such as virtual machine and service templates, and profiles.
VMM consoleThe program that you can use to connect to a VMM management server in order to centrally view and manage physical and virtual resources, such as virtual machine hosts, virtual machines, services, and library resources.
VMM library and VMM library serverThe catalog of resources (for example, virtual hard disks, templates, and profiles) that are used to deploy virtual machines and services.

A library server hosts shared folders that are used to store file-based resources in the VMM library.
VMM command shellThe Windows PowerShell–based command shell that makes available the cmdlets that perform all functions in VMM.
VMM Self-Service Portal (optional) Note: As of System Center 2012 Service Pack 1 (SP1), the VMM Self-Service Portal has been removed.A website that users who are assigned to a self-service user role can use to deploy and manage their own virtual machines in private clouds.

For information about deploying VMM, see Deploying System Center 2012 - Virtual Machine Manager.

You can perform the following tasks to configure security in VMM.

The following resources in VMM are referred to as ‘fabric’, and you must configure them before you can deploy virtual machines and services to a private cloud or to virtual machine hosts. You can use VMM to configure and manage the following fabric resources.

ResourceDescriptionFor more information
Virtual machine hostsMicrosoft Hyper-V Server or Hyper-V in Windows Server, Citrix XenServer, and VMware ESX hosts and host clusters on which you will deploy virtual machines and services.

You can create host groups to organize your hosts based on physical site location, resource allocation, or other criteria.

After you configure your hosts and your networking, storage, and library resources, you can perform the following tasks to deploy virtual machines and services in VMM.

In VMM, a service is a set of virtual machines that are configured and deployed together and are managed as a single entity. An example is the deployment of a multiple-tier line-of-business application.

Configure self-serviceCreate a self-service user role that can create, deploy, and use virtual machines and services in one or more private clouds.Configuring Self-Service in VMM
Create sequenced applicationsUse Microsoft Server Application Virtualization (Server App-V) to sequence applications that VMM will deploy.Microsoft Server Application Virtualization
Create profilesCreate profiles (hardware profiles, guest operating system profiles, application profiles, and SQL Server profiles) that will be used in a template to deploy virtual machines.

For example, an application profile provides instructions for installing applications such as Server App-V applications, Web Deploy applications, and SQL Server data-tier applications (DACs), and for running scripts during the deployment of a virtual machine.

You can use hardware profiles and guest operating system profiles when you deploy virtual machines through a virtual machine template or a service template. You can use application profiles and SQL Server profiles only when you deploy virtual machines through a service template.
