+
+# LIBVIRT_SHUTDOWN
+# Valid options:
+# * managedsave - Performs a state save external to the VM (for hypervisors
+# supporting this operation). qemu-kvm will stop the CPU
+# and save off all state to a separate file. When the
+# machine is started again, it will resume like nothing
+# ever happened. This is guarenteed to always successfully
+# stop your machine and restart it.
+#
+# * shutdown - Sends an ACPI shutdown (think of this as a request to
+# your guest to shutdown). There is no way to distinguish
+# between guests that are ignoring the shutdown request or
+# are stuck or are taking a long time to shutdown. We will
+# wait LIBVIRT_MAXWAIT seconds before yanking the power
+# out.
+#
+# * destroy - Immediately stop all running guests. Use with caution as
+# this can leave the guest in a corrupted state and might
+# lead to data loss.

+
+#LIBVIRT_SHUTDOWN="managedsave"

+# LIBVIRT_MAXWAIT
+# Timeout in seconds until stopping a guest and "pulling the plug" on the

+#LIBVIRT_MAXWAIT="500"
+
+
+# LIBVIRT_NET_SHUTDOWN
+# If libvirtd created networks for you (e.g. NATed networks) then this init
+# script will shut them down for you if this is set to 'yes'. Otherwise,
+# the networks will be left running. For this option to be useful you must
+# have enabled the 'virt-network' USE flag and have had libvirt create a
+# NATed network for you. Valid values: 'yes' or 'no'
