Hi,

Xen4.1 datasheet tells that credit2 scheduler is designed for latency sensitive workloads. Does it have some improvement on the hybrid workload including both the cpu-bound and latency-sensitive i/o work? For example, if a VM runs a cpu-bound task burning the cpu and a i/o-bound (latency-sensitive) task simultaneously, will the latency be guaranteed? And how?

Regards,
Cong
