From 3c73d5f9473dfa897201dc03dc719bd1ccf8b77b Mon Sep 17 00:00:00 2001 From: Roger Pau Monne Date: Fri, 14 Sep 2012 10:02:49 +0100 Subject: xl: error if vif backend!=0 is used with run_hotplug_scripts Print an error and exit if backend!=0 is used in conjunction with run_hotplug_scripts. Currently libxl can only execute hotplug scripts from the toolstack domain (the same domain xl is running from). Added a description and workaround of this issue on xl-network-configuration.
