[Libvir] [PATCH] Xen driver doesn't support autostart, so remove it from xen_unified

Our implementation of the Xen driver doesn't support autostart[*]. However xen_unified.c has a loop for get/setAutostart which causes it to return an error without setting virterror first. This patch removes that loop. Rich. [*] Although Xen supports it, by putting files in /etc/xen/autostart/ (at least that was the "old Xen" way before the current insanity of getting rid of config files was invented). -- Emerging Technologies, Red Hat - http://et.redhat.com/~rjones/ Registered Address: Red Hat UK Ltd, Amberley Place, 107-111 Peascod Street, Windsor, Berkshire, SL4 1TE, United Kingdom.
