| <para>Once you have at least one VM set up in the way you want, you can use it as the prototype for other VMs.</para> |
| <orderedlist> |
| <listitem><para>Create and start a virtual machine using any of the techniques given in <xref linkend="creating-vms"/>.</para></listitem> |

| <listitem><para>Wait for the VM to stop. When the status shows Stopped, go to the next step.</para></listitem> |
| <listitem><para>Click Create Template and provide the following:</para> |

| <listitem><para><emphasis role="bold">OS Type</emphasis>. This helps &PRODUCT; and the hypervisor perform |
