Research on Significance of VCPU Scheduling for SR-IOV on NUMA platform
Virtualization is vital important in server consolidation.Using virtualization technology,a single physical machine can provide multiple isolated virtual machine for users,which will improve the overall system resources usage.However,In virtualization environment,Non-Uniform Memory Access Architecture(NUMA)problem is also a very important parameter that affects servers performance.To solve NUMA problem,many solutions have been proposed to reduce its performance impact on virtual machines and improve the overall system performance.Hardware Single Root I/O Virtualization(SR-IOV)is a solution for high performance network processing,but when SR-IOV technology is running on a NUMA platform,there will also generate the traditional problem about NUMA.We take into vCPU allocation strategy of VM to check the performance influence of a VM.We also conduct detailed experiments to evaluate our design and implement under a physical network environment.The result shows that our design achieves a significant improvement in terms of network performance,while introducing a small overhead to the original system.
