You can manage individual virtual machines or a group of virtual machines that belongs to a host or cluster. If you have vCenter Server systems in your environment that are connected with vCenter Linked Mode, you can connect to that vCenter Server system and view and manage all virtual machines that run in that system.
You can install the Client Integration Plug-in to access the virtual machine's console. From the console, you can change the guest operating system settings, use applications, browse the file system, monitor system performance, and so on. Use snapshots to capture the state of the virtual machine at the time you take the snapshot.
To migrate virtual machines using cold or hot migration, including vMotion, vMotion in environments without shared storage, and Storage vMotion, see the vCenter Server and Host Management documentation.
