mlxconfig -d /dev/mst/mt4129_pciconf1 set SRIOV_EN=1 NUM_OF_VFS=16

Use the above command to enable the Sriov function and create 16 VFs, and then check through LSPCI that it is not enabled

If it can be opened normally, the following information will be displayed

Hey, can you do:
mlxconfig -d /dev/mst/mt4129_pciconf1 query

Changing NUM_OF_VFS require to reboot the server.
Did you reboot?

Changing NUM_OF_VFS require to reboot the server. Did you reboot?

I have restarted many times already

[adrianchiris]

can you paste the output of:

cat /sys/bus/pci/devices/<NIC PCI ADDRESS>/sriov_totalvfs

to create VFs you need to write the desired number of VFs to the following file:

echo 8 > /sys/bus/pci/devices/<NIC PCI ADDRESS>/sriov_numvfs

can you also paste the output of:
mlxconfig -d <NIC PCI ADDRESS> -e q
