Berrange" , Stefan Hajnoczi , Fam Zheng , "Dr . David Alan Gilbert" , peterx@redhat.com IOThread is a general framework that contains IO loop environment and a real thread behind. It's also good to be used internally inside qemu. Provide some helpers for it to create iothreads to be used internally.
