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.
4.10.1 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:
E_IPOIB_LOAD=yes
Step 2. Restart the InfiniBand drivers.
/etc/init.d/openibd restart
4.10.2 Configuring the Ethernet Tunneling Over IPoIB Driver
When eth_ipoib is loaded, number of eIPoIB interfaces are created, with the following default
naming scheme:
ethX, where X represents the ETH port available on the system.
To check which eIPoIB interfaces were created:
cat /sys/class/net/eth_ipoib_interfaces
