I have a Dual-port Intel 82599 NIC.
My testbed is Ubuntu 14.04, ixgbe driver 5.2.3, ixgbevf 4.2.1.
I initialize one VF by executing
echo 1 >> /sys/bus/pci/devices/0000\:06\:00.0/sriov_numvfs
However, the number of queue pair attached to this VF is only 1, as shown in the dmesg
[ 727.882194] ixgbevf 0000:06:10.0: Multiqueue Disabled: Rx Queue count = 1, Tx Queue count = 1
This is may be not consistent with the Intel 82599 data sheet, which shows a pool of queue pairs (e.g., 8, 4 or 2) is assigned to the VF interface.
My question is how to configure VF multiple queue correctly?

Hi Wtao000,
Please try using below command to add the queue, as stated on page 11 at
https://www.intel.com/content/dam/www/public/us/en/documents/technology-briefs/xl710-sr-iov-config-guide-gbe-linux-brief.pdf
example:
# modprobe i40e max_vfs=4,4

Sorry, this may still not work.
My NIC controller is 82599. I have run "modprobe ixgbe max_vfs=4,4".
It still can not work.

Hi Wtao000,
The latest 82599 physical function and virtual function drivers can support multi queue feature. Can you help clarify if the VF is being assigned to a VM and how many vCPU are assigned to the VM?
Thanks,
Sharon
