With these advantages, virtualization become the technology which is widely used to support cloud computing. With the computer hardware industry promote multi-core system continuously, how to allocate hardware resources to the virtual machine between physical CPUs becomes the key issue of which affects the overall system performance.
Credit Scheduler is Xen default virtual CPU scheduler, having better fairness for multi-core systems with global load balancing, but bad performance for latency-sensitive workloads. In order to solve this problem, this paper proposed the Distribute Weighted Round-Robin scheduling algorithm using on Xen virtual CPU scheduler, it can get less response time for latency-sensitive workloads, also have good fairness, so that enhance 20% to 33% of the performance of the Xen virtualization system.
