From 8b3be172a3f225539a807711318c23001e84f359 Mon Sep 17 00:00:00 2001 From: Stefano Stabellini Date: Mon, 9 Aug 2010 17:07:50 +0100 Subject: [PATCH] xl: tell the user about non-existent domains The error message when one wants to list a non-existent domain is at best misleading (libxl_domain_info failed (code -5)). This patch catches this specific error and tells the user that the requested domain does not exist: Error: Domain '42' does not exist.
