- `linked` (bool) - By default Packer creates a 'full' clone of the virtual machine specified in source_path. The resultant virtual machine is fully independant from the parent it was cloned from. Setting linked to true instead causes Packer to create the virtual machine as a 'linked' clone. Linked clones use and require ongoing access to the disks of the parent virtual machine. The benefit of a linked clone is that the clones virtual disk is typically very much smaller than would be the case for a full clone. Additionally, the cloned virtual machine can also be created much faster. Creating a linked clone will typically only be of benefit in some advanced build scenarios. Most users will wish to create a full clone instead. Defaults to false. - `vm_name` (string) - This is the name of the VMX file for the new virtual machine, without the file extension. By default this is packer-BUILDNAME, where "BUILDNAME" is the name of the build.
