From 19045bcf3b738f98718fc46e50b35e315c78cf3c Mon Sep 17 00:00:00 2001 From: Roger Pau Monne Date: Wed, 2 Oct 2013 11:24:25 +0200 Subject: [PATCH] libxl: make hotplug execution conditional on backend_domid == domid MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit libxl currently refuses to execute hotplug scripts if the backend domid of a device is different than LIBXL_TOOLSTACK_DOMID. This will prevent libxl from executing hotplug scripts when running on a domain different than LIBXL_TOOLSTACK_DOMID, we should instead check if backend_domid is different than current domid.
