VMware vSphere and the vSphere Hypervisor support VMq only (NetQueue) VMware’s SR-IOV implementation does not support vMotion, HA or Fault Tolerance. SR-IOV also requires the vSphere Distributed Switch, meaning customers have to upgrade to the highest vSphere edition to take advantage of this capability. No such restrictions are imposed when using SR-IOV in Hyper-V, ensuring customers can combine the highest levels of performance with the flexibility they need for an agile infrastructure. vSphere Hypervisor / vSphere 5.x Ent Information: http://www.vmware.com/pdf/Perf Best Practices vSphere5.5.pdf
