Deploying an OVF template on an ESX 4.x or ESXi 5/4.x Server
An OVF template is a virtual machine that includes the software you plan to run on the machine. You can deploy an OVF template that contains Symantec Messaging Gateway Virtual Edition on a VMware ESX Server 4.x or VMware ESXi Server 4.x. To deploy the OVF template, use a vSphere or vCenter client on a different computer than the computer hosting your ESX or ESXi Server.
You may want to ensure that your guest computer is configured to restart when the host computer restarts. Consult your VMware documentation for more information.
If you cannot successfully complete this procedure, you can instead use an OS restore disk.
