Restarting a virtual machine is analogous to rebooting a computer. You may need to restart a virtual machine if an operating system update requires you to restart the virtual machine, for example Microsoft Windows™ updates.
To restart virtual machines:
Click the Servers and VMs tab.
Select the server pool on which the virtual machines reside in the navigation tree.
Select Virtual Machines from the Perspective drop-down list. Select one or more virtual machines in the management pane, and click Restart
.
The virtual machines are restarted.
If a virtual machine has not fully started, a restart request may not succeed as the virtual machine may not be ready to initiate the request. In this case, you may need to abort the restart job and try again later. Alternately, kill the virtual machine and start it again.
