How many threads do we want to have the threadpool use? Currently theres a thread allocated for each VCPU + _SC_NPROCESSORS_ONLN I/O threads.

This number can grow to be pretty big once we start adding multiple devices. -- Sasha. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
