In virtualization environment, a virtual machine can be expose to the physical network by per-
forming the next setting:
Step 1. Create a virtual bridge
Step 2. Attach the para-virtualized interface created by the eth_ipoib driver to the bridge
Step 3. Attach the Ethernet interface in the Virtual Machine to that bridge
The diagram below describes the topology that was created after these steps:
The diagram shows how the traffic from the Virtual Machine goes to the virtual-bridge in the
Hypervisor and from the bridge to the eIPoIB interface. eIPoIB interface is the Ethernet interface
that enslaves the IPoIB interfaces in order to send/receive packets from the Ethernet interface in
the Virtual Machine to the IB fabric beneath.
4.8.1 Enabling the eIPoIB Driver
Once the mlnx_ofed driver installation is completed, perform the following:
Step 1. Open the /etc/infiniband/openib.conf file and include:
Step 2. Restart the InfiniBand drivers.
E_IPOIB_LOAD=yes
/etc/init.d/openibd restart
