How do I enable SR-IOV in Mellanox?

I. Enable SR-IOV on the Firmware

  1. Run MFT. # mst start. Starting MST (Mellanox Software Tools) driver set.
  2. Locate the HCA device on the desired PCI slot. # mst status.
  3. Query the Status of the device. # mlxconfig -d /dev/mst/mt4115_pciconf0 q.
  4. Enable SR-IOV , set the desired number of VFs. SRIOV_EN=1.
  5. Reboot the server.

Does KVM support SR-IOV?

SR-IOV Overview vSRX on KVM supports single-root I/O virtualization ( SR-IOV ) interface types. SR-IOV is a standard that allows a single physical NIC to present itself as multiple vNICs, or virtual functions (VFs), that a virtual machine (VM) can attach to.

Should I enable or disable SR-IOV?

Enabled—Enables a hypervisor to create virtual instances of a PCIe device, potentially increasing performance. Disabled—Does not enable a hypervisor to create virtual instances of a PCIe device.

How do I know if SR-IOV is enabled?

Verify support Verify if the PCI device with SR-IOV capabilities is detected. This example lists an Intel 82576 network interface card which supports SR-IOV. Use the lspci command to verify whether the device was detected.

How do I disable SR-IOV?

Use the up or down arrow keys to navigate to the SR-IOV menu option, and press Enter. The SR-IOV dialog box appears. In the SR-IOV dialog box, use the up and down arrow keys to select Disabled and press Enter.

What is DPDK and SR-IOV?

The DPDK uses the SR-IOV feature for hardware-based I/O sharing in IOV mode. Therefore, it is possible to partition SR-IOV capability on Ethernet controller NIC resources logically and expose them to a virtual machine as a separate PCI function called a “Virtual Function”.

What does SVM mode do?

SVM Mode is an option within an AMD motherboard’s BIOS to enable what’s called a Secure Virtual Machine. In addition to providing a secure virtual machine environment, SVM also allows for more direct access to the hardware than without.
