From 784528b67d0f7bfb2485f53b4424dd6d2ac72d51 Mon Sep 17 00:00:00 2001 From: Roger Pau Monne Date: Thu, 26 Jul 2012 10:35:32 +0100 Subject: libxl: use libxl__xs_path_cleanup on device_destroy Since the hotplug script that was in charge of cleaning the backend is no longer launched, we need to clean the backend by ourselves, so use libxl__xs_path_cleanup instead of xs_rm.
