When you connect directly to an
ESXi host or vCenter Server system using the vSphere Client, you can open a console to any of the host's virtual machines, add and remove virtual machines in the host's inventory, and manage virtual machine snapshots.
Edit Virtual Machine Startup and Shutdown Settings You can configure virtual machines running on an ESXi host to start up and shut down with the host. You can also set the default timing and startup order for selected virtual machines. This ability allows the operating system to save data when the host enters maintenance mode or is being powered off for another reason.
Open a Console to a Virtual Machine With the vSphere Client, you can access a virtual machine's desktop by launching a console to the virtual machine. From the console, you can perform activities within the virtual machine such as configure operating system settings, run applications, monitor performance, and so on.
Adding and Removing Virtual Machines You add virtual machines to the vCenter Server inventory through their managed hosts. You can remove virtual machines from vCenter Server, from their managed host’s storage, or from both.
Using Snapshots To Manage Virtual Machines Snapshots preserve the state and data of a virtual machine at the time you take the snapshot. Snapshots are useful when you must revert repeatedly to the same virtual machine state, but you do not want to create multiple virtual machines.
