- `format` (string) - Either "ovf", "ova" or "vmx", this specifies the output format of the exported virtual machine. This defaults to "ovf" for remote (esx) builds, and "vmx" for local builds. Before using this option, you need to install ovftool. Since ovftool is only capable of password based authentication remote_password must be set when exporting the VM from a remote instance. If you are building locally, Packer will create a vmx and then export that vm to an ovf or ova. Packer will not delete the vmx and vmdk files; this is left up to the user if you don't want to keep those files. - `ovftool_options` ([]string) - Extra options to pass to ovftool during export. Each item in the array is a new argument. The options `--noSSLVerify`, `--skipManifestCheck`, and `--targetType` are used by Packer for remote exports, and should not be passed to this argument. For ovf/ova exports from local builds, Packer does not automatically set any ovftool options. - `skip_export` (bool) - Defaults to `false`. When true, Packer will not export the VM. This can be useful if the build output is not the resultant image, but created inside the VM. - `keep_registered` (bool) - Set this to true if you would like to keep a remotely-built VM registered with the remote ESXi server. If you do not need to export the vm, then also set `skip_export: true` in order to avoid unnecessarily using ovftool to export the vm. Defaults to false. - `skip_compaction` (bool) - VMware-created disks are defragmented and compacted at the end of the build process using vmware-vdiskmanager or vmkfstools in ESXi. In certain rare cases, this might actually end up making the resulting disks slightly larger. If you find this to be the case, you can disable compaction using this configuration value. Defaults to false. Default to true for ESXi when disk_type_id is not explicitly defined and false otherwise.
