Virtual Machine Manager.
Virtual Machine Host A virtual machine host is a physical computer that hosts one or more virtual
machines. Hosts are added to System Center Virtual Machine Manager by using the Add Hosts Wizard in the System Center Virtual Machine Manager Administrator Console. When a host is added to System Center Virtual Machine Manager, an agent is automatically installed on the host system. When you add a Windows® based host, System Center Virtual Machine Manager automatically installs or upgrades the appropriate version of Virtual Server or enables Hyper-V role.
In order to manage Virtual Server hosts running the Windows Server® 2003 operating system the correct version of Windows Remote Management (WinRM) must be installed.
Host Groups Virtual machine hosts can be organized into groups, which provide ease of
monitoring and management of hosts and virtual machines. The host groups can be used in a manner that works best for your organization.
A host group‘s most basic function is to act as a container to group hosts and virtual machines in a meaningful way. Host groups can be used to:
Set aside resources on the hosts for the use of the host operating system.
Designate hosts that are used for self-service.
Designate which hosts are connected to a storage area network (SAN). (This is a best practice.)
Enable the automatic placement of virtual machines on the best host in a group of hosts.
Inheritance of Host Group Properties A child host group can inherit host reserve settings and role delegation from its
parent group. However, property inheritance works differently for the following two features:
Host reserves. When changing the host reserves for a parent host group, the administrator can choose whether to cascade the host reserve settings to the hosts in the child groups. If inheritance is enabled, the host reserve settings in the child groups will be overwritten.
Role Delegation. If a parent host group is used for virtual Role
