[Xen-devel] [PATCH] Add xl domUs default configuration file

[Fabio Fantoni <fabio.fantoni@xxxxxxxxxx>]

This patch add xl domUs default configuration file, must be improved and 
implemented in the core xl.
About implementation on core i try but fail, about this configuration 
file i start from other xm, removed some unnecessary things or specific 
such as name and uuid missed in xl and add other, some description need 
to be improved.

+# for a domain to stop: poweroff, reboot, and crash.  For each of these you
+# may specify:

+#   "destroy",        meaning that the domain is cleaned up as normal;
+#   "restart",        meaning that a new domain is started in place of 
the old
+#                     one;
+#   "preserve",       meaning that no clean-up is done until the domain is
+#                     manually destroyed (using xm destroy, for 
example); or
+#   "rename-restart", meaning that the old domain is not cleaned up, but is
+#                     renamed and a new domain started in its place.
+#
+# In the event a domain stops due to a crash, you have the additional 
options:

+#   "coredump-destroy", meaning dump the crashed domain's core and then 
destroy;
+#   "coredump-restart', meaning dump the crashed domain's core and the 
restart.
