A comparison of the performance and scalability of Xen and KVM hypervisors

摘要: Virtualization is the fundamental technology for corporate data center consolidation and cloud computing. Companies academic institutions consolidate their servers through virtualization in search efficient hardware resource usage, lower energy consumption, improved fault tolerance, increased security. In this paper, we investigate performance scalability of two open source platforms: Xen Kernel-based Virtual Machine (KVM). We analyze influence number virtual machines on several benchmarks that measure compute power, network, I/O throughput. are running top a single physical host. The results show these solutions have similar behavior. An important degradation noticed when equals or exceeds core available. Hyper-threading boots by small margin. effect throughput even more noticeable, although were using LVM logical volumes as disk images our tests.
