+Create a virtual hardware watchdog device. Once enabled (by a guest

+the guest or else the guest will be restarted.
+
+The @var{model} is the model of hardware watchdog to emulate. Choices
+for model are: @code{ib700} (iBASE 700) which is a very simple ISA
+watchdog with a single timer, or @code{i6300esb} (Intel 6300ESB I/O
+controller hub) which is a much more featureful PCI-based dual-timer
+watchdog. Choose a model for which your guest has drivers.

+@item -watchdog-action @var{action}
+
+The @var{action} controls what QEMU will do when the watchdog timer
+expires.
+The default is
+@code{reset} (forcefully reset the guest).
+Other possible actions are:
+@code{shutdown} (attempt to gracefully shutdown the guest),
+@code{poweroff} (forcefully poweroff the guest),
+@code{pause} (pause the guest),
+@code{debug} (print a debug message and continue), or
+@code{none} (do nothing).
+
+Note that the @code{shutdown} action requires that the guest responds
+to ACPI signals, which it may not be able to do in the sort of
+situations where the watchdog would have expired, and thus
+@code{-watchdog-action shutdown} is not recommended for production use.
