+# @guest-suspend-hybrid
+#
+# Save guest state to disk and suspend to ram.
+#
+# This command requires the pm-utils package to be installed in the guest.
+#
+# IMPORTANT: guest-suspend-hybrid requires QEMU to support the 'wakeup' command.
+# Thus, it's *required* to query QEMU for the presence of the 'wakeup' command
+# before issuing guest-suspend-hybrid.
+#
+# Returns: nothing on success
+#          If hybrid suspend is not supported, Unsupported
+#
+# Notes: o This is an asynchronous request. There's no guarantee a response
+#          will be sent
+#        o It's strongly recommended to issue the guest-sync command before
+#          sending commands when the guest resumes
+#
+# Since: 1.1
