+ * @params: pointer to scheduler parameter objects
+ * @nparams: number of scheduler parameter
+ * (this value should be same or less than the returned value
+ * nparams of virDomainGetSchedulerType)
+ * @flags: an OR'ed set of virDomainMemoryModFlags
+ *
+ * Change the scheduler parameters according to the specified flags
+ *
+ * @flags may include VIR_DOMAIN_SCHED_PARAMS_LIVE or
+ * VIR_DOMAIN_SCHED_PARAMS_CONFIG, both flags may be set, and both flags
+ * requires the domain is running.
+ * If VIR_DOMAIN_SCHED_PARAMS_LIVE is set, the change affects a running

+ * If VIR_DOMAIN_SCHED_PARAMS_CONFIG is set, the change affects both the

+ * domains or the domain is not active.

+ * Returns -1 in case of error, 0 in case of success.
