+ * This updates the definition of a domain stored in a saved state

+ * @dxml can be used to alter host-specific portions of the domain XML

+ * device while the domain is stopped.
+ *
+ * Normally, the saved state file will remember whether the domain was
+ * running or paused, and restore defaults to the same state.
+ * Specifying VIR_DOMAIN_SAVE_RUNNING or VIR_DOMAIN_SAVE_PAUSED in
+ * @flags will override the default saved into the file; omitting both
