A virtual machine before it's started
With Hyper-V, a virtual machine runs in the background until you connect to it with Hyper-V
Manager. A running VM doesn't require using Hyper-V Manager, nor does it require anybody
to be logged on to the server. Furthermore, you can configure a VM to start and shut down
automatically when the host server starts and shuts down. In addition, like any OS, you can
manage a VM remotely by using tools such as Remote Desktop and MMCs.
When you want to configure and manage a VM's properties or access it locally, you do
need to run Hyper-V Manager. The middle pane of Hyper-V Manager shows all installed vir-
tual machines at the top; in Figure 2-17, one VM is running and one VM is powered off. This
pane also displays name, state, CPU usage, uptime, and current operations for each VM.
Normally, the Operations column doesn't display anything unless you perform a task such as
exporting a VM or creating a snapshot of it. When you select a VM, the Snapshots section
shows a list of snapshots created for it. If you click the VM's name in the Snapshots section,
you see a screen shot of the VM at the time the snapshot was taken along with the time and
date it was taken. The bottom section shows a real-time screen shot of a running VM. When
a running VM changes, the screen shot in Hyper-V Manager reflects the change almost
immediately.
Connecting to a virtual machine opens a window that serves as the user interface to the VM
and looks similar to a remote desktop connection. You can connect to a VM by using any of the
following methods:
• Right-click the VM and click Connect.
• Double-click the VM.
• Select the VM and double-click its screen shot in the bottom section.
• Select the VM and click Connect in the Actions pane.
