     using this configuration value. Defaults to `false`.
 
+-   `skip_export` (boolean) - Defaults to `false`. When enabled, Packer will
+    not export the VM. Useful if the build output is not the resultant image,
+    but created inside the VM.
+
+-   `keep_registered` (boolean) - Set this to `true` if you would like to keep
+    the VM registered with the remote ESXi server. This is convenient if you
+    use packer to provision VMs on ESXi and don't want to use ovftool to
+    deploy the resulting artifact (VMX or OVA or whatever you used as `format`).
+    Defaults to `false`.
+
+-   `ovftool_options` (array of strings) - Extra options to pass to ovftool
+    during export. Each item in the array is a new argument. The options
+    `--noSSLVerify`, `--skipManifestCheck`, and `--targetType` are reserved,
+    and should not be passed to this argument.
+
+-   `format` (string) - Either "ovf", "ova" or "vmx", this specifies the output
+    format of the exported virtual machine. This defaults to "ovf".
+    Before using this option, you need to install `ovftool`.
+
 -   `tools_upload_flavor` (string) - The flavor of the VMware Tools ISO to
     upload into the VM. Valid values are `darwin`, `linux`, and `windows`. By
     default, this is empty, which means VMware tools won't be uploaded.
