Aiming at the problem that the performance and predictability of application are degraded caused by the uncertainty of VCPUs’ (Virtual CPU) scheduling order in virtual computing environment, this paper presents a VCPU collaborative scheduling method based on virtual domain (VDS). It combines co-scheduling and virtual domain, which can avoid the uncertainty of VCPUs’ scheduling order and improve the performance and predictability of application. The performance of the proposed method is analyzed and validated through various workloads. The results show that the proposed method can effectively improve the performance and predictability of application.
