[Xen-devel] What is the option 'e' used for in 'xl create' command

Hi, There is an 'e' option when running the following xl command: - xl create - xl restore - xl migrate - xl remus The 'e' option is used to "Do not wait in the background (on ) for the death of the domain". This option dates back to Dec 2009. Would you please help me understand the objective
