The VMware vSphere Client (vSphere Client) allows you to deploy and export virtual machines, virtual appliances, and vApps stored in Open Virtual Machine Format (OVF). An appliance is a pre-configured virtual machine that typically includes a preinstalled guest operating system and other software.

Deploying an OVF template allows you to add pre-configured virtual machines to your vCenter Server or ESXi inventory. Deploying an OVF template is similar to deploying a virtual machine from a template. However, you can deploy an OVF template from any local file system accessible from the vSphere Client machine, or from a remote web server. The local file systems can include local disks (such as C:), removable media (such as CDs or USB keychain drives), and shared network drives.

Exporting OVF templates allows you to create virtual appliances that can be imported by other users. You can use the export function to distribute pre-installed software as a virtual appliance, or as a means of distributing template virtual machines to users, including users who cannot directly access and use the templates in your vCenter Server inventory.
