+# LIBVIRT_SHUTDOWN
+# Valid options:

+#
+# * 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

-# LIBVIRTD_KVM_SHUTDOWN
-# Valid options:

-# on your machine and it begins a graceful shutdown). If your
-# VM ignores this, it will have the power yanked out from under
-# it in LIBVIRTD_KVM_SHUTDOWN_MAXWAIT seconds.
-# * managedsave - Performs a state save external to the VM. qemu-kvm will stop
-# 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. However it may take some time to finish.
-# * none - No attempts will be made to stop any VMs. If you are restarting your
