Step 4. Choose a Mellanox virtual function according to its PCI device (e.g., 00:03.1)

Step 5. If the Virtual Machine is up reboot it, otherwise start it.

Step 6. Log into the virtual machine and verify that it recognizes the Mellanox card. Run:

Step 7. Add the device to the /etc/sysconfig/network-scripts/ifcfg-ethX configuration file.

The MAC address for every virtual function is configured randomly, therefore it is not nec-

essary to add it.

4.13.5 Uninstalling SR-IOV Driver

 To uninstall SR-IOV driver, perform the following:

Step 1. For Hypervisors, detach all the Virtual Functions (VF) from all the Virtual Machines (VM)

or stop the Virtual Machines that use the Virtual Functions.

Please be aware, stopping the driver when there are VMs that use the VFs, will cause machine to hang.

Step 2. Run the script below. Please be aware, uninstalling the driver deletes the entire driver's file,

but does not unload the driver.

Step 3. Restart the server.

4.13.6 Burning Firmware with SR-IOV

The following procedure explains how to create a binary image with SR-IOV enabled that has 63

VFs. However, the number of VFs varies according to the working mode requirements.

 To burn the firmware:

Step 1. Verify you have MFT installed in your machine.

Step 2. Enter the firmware directory, according to the HCA type (e.g. ConnectX®-3).

The path is: /mlnx_ofed/firmware/<device>/<FW version>

Step 3. Find the ini file that contains the HCA's PSID. Run:

lspci | grep Mellanox
