KVM Virtualized I/O Performance

Achieving Unprecedented I/O Performance Using Virtio-Blk-Data-Plane Technology Preview in SUSE Linux Enterprise Server 11 Service Pack 3. The Kernel-based Virtual Machine (KVM) hypervisor has earned a reputation as the highest performing hypervisor in virtualization benchmarks, holding the top seven results in SPECvirt_sc2010 [1] and recently achieving leadership results on SAP's 2-tier SD benchmark [2] and TPC-C benchmark [3]. One of the key ingredients to this success is KVM's ability to handle the high I/O rates required by enterprise workloads, such as databases, ERP systems, and low-latency financial trading applications that are running in virtual machines.
