#change_host_name(name) ⇒ Object

Windows needs a modification of the base method because Windows guest names cannot be fully-qualified domain names (they cannot contain the "." character). Therefore, modify the input name to convert illegal characters to legal replacements.

Parameters:

  • name (String) —

    The new hostname to apply on the guest
