| Abstract: | This paper studies the influence of multi-VM and multi-CPU for expansibility of XEN VM network full-virtualization mechanism. Experimental results show that when the VM increases or the amount of CPU goes beyond the limit, the network performance will be decreased. It analyzes the key factors’ influence on the expansibility, that is schedule mechanism and event channel mechanism. |
