4. Activate Virtual Functions (VFs).
The maximum number of supported virtual functions depends on the type of card. The example below shows
that the PF identifier 82:00.0 supports a total of 63 VFs.
[arista@localhost]$ cat/sys/bus/pci/devices/0000\:82\:00.0/sriov_totalvfs
63
To activate the seven VFs per PFs and make them persistent after reboot, add the line options
igb max_vfs=7
in
ixgbe.conf
and the
sriov.conf
files in
/etc/modprobe.d
Use the
rmmod ixgbe
and
modprobe ixgbe
Linux commands to unload and reload the module.
5. Verify the VFs are detected.
Verify the VFs are detected by using the
lspci | grep Ethernet
Linux command. For the two identifiers
82:00.0 and 82:00.1, 14 VFs are detected.

6. Locate the serial numbers for the PFs and VRFs.
Locate the serial numbers for the PFs and VFs. The Linux
virsh nodedev-list | grep 82
command
below displays the serial number for identifiers 82:00.0 and 82:00.1. The first two numbers are the serial numbers
for the PFs and the remaining are the serial numbers for the VFs.
# virsh nodedev-list | grep 82
