This should be 0,

> +    VIR_DOMAIN_SCHEDPARAM_CONFIG  = (1 << 2), /* Affect next boot */

and these 1 and 2 (1 << 0, 1 << 2).

Can @nparams be 0, and if so, can @params be NULL and use this as a way
to query the correct nparams setting (rather than having to call
virDomainGetSchedulerType)?  Related to my comment on Matthias's
libvirt.c cleanup.
