<div>
  (Optional) The number of cores per socket (virtual sockets are then the number of CPU cores divided by this) to create the new VM with.
  <p>
  Applied in the very same operation that creates the VM, rather than cloning at the source's size
  and reconfiguring afterwards. Has the same meaning as the setting of the same name of the
  "Reconfigure CPU"/"Reconfigure Memory" steps. Leave blank to keep the source VM's (or template's)
  own value. Variables can be used.
  </p>
  <p>
  The number of CPU cores, whether set here or kept from the source, has to be a multiple of this.
