Hi,
Thanks.
I just tried this :
modprobe ixgbe max_vfs=2,2
But it creates 4 devices "ONLY " for the first port.
# virsh nodedev-list | grep 25
pci_0000_25_00_0
pci_0000_25_00_1
*pci_0000_25_10_0*
*pci_0000_25_10_1*
*pci_0000_25_10_2*
*pci_0000_25_10_3*
#
dmesg output while carrying out this :
modprobe ixgbe max_vfs=2,2

There are actually four ixgbe ports present :

driver: ixgbe
version: 3.18.7
firmware-version: 0x5e0b0001
bus-info: 0000:25:00.0 <==
[root@sv2-13 rules.d]# ethtool -i eth1
driver: ixgbe
version: 3.18.7
firmware-version: 0x5e0b0001
bus-info: 0000:25:00.1
[root@sv2-13 rules.d]# ethtool -i eth2
driver: ixgbe
version: 3.18.7
firmware-version: 0x5e0b0001
bus-info: 0000:2d:00.0
[root@sv2-13 rules.d]# ethtool -i eth3
driver: ixgbe
version: 3.18.7
firmware-version: 0x5e0b0001
bus-info: 0000:2d:00.1
------------------------------------------------------------------------------------------------------------------
All the Virtual functions are created for eth0 alone/
Please refer bus-info for eth0.
Please let me know how to avoid this and get VFs created for all interfaces.
