Hi All,
The KVM SR-IOV driver enables support for SR-IOV devices, including Infiniband, in KVM virtual machines. The add-on has been developed for HPC orientated Clouds and includes a number of VM  performance enhancements.
The driver supports two modes for passing SR-IOV devices into VMs, generic and mlnx_ofed2. The generic mode is cable of passing any SR-IOV device into VMs, not limited to network devices.
The mlnx_ofed2 mode is tuned to pass IP information into VMs via GUIDs and also supports IB network isolation though a modification to the ovswitch VNM driver and IB partitions.
A HPC mode option can also be enabled to improve CPU and memory performance of the VM by passing though the exact CPU model and detecting and respecting NUMA nodes.
