Hello,

I enabled sr-iov on my servers but virtual function ports dont come up online.

Code: 
/etc/network/interfaces

allow-hotplug enp3s17f7
iface enp3s17f7 inet static
        address  10.1.1.12
        netmask  255.255.255.0

How can i enable it on boot?

Thanks

Talion
 
This works for me : http://enricorossi.org/blog/2016/intel_sr-iov_on_Debian_Stretch/

My udev rule is saved here /etc/udev/rules.d/99-sriov.rules and looks like:
Code: 
KERNEL=="0000:08:00.0", SUBSYSTEM=="pci", DRIVER=="igb", ATTR{vendor}=="0x8086", ATTR{device}=="0x10c9", ATTR{sriov_numvfs}="7"

Note that your kernel address/vendor/driver and device may be different. The link explains how to find them.

sriov_numvfs is the number of virtual functions, my rule lists 7.
 
Hello Trystan,

Actually i meant the activating interface rather than VF itself. My VFs are working working correctly but they are not online. I needed to activate them manually by "ip link set enp3s17f7 up" to activate them after that it works and i can ping.


But this method fix this warning;

Code: 
[    1.888447] ixgbe 0000:03:00.1: Enabling SR-IOV VFs using the max_vfs module parameter is deprecated.
[    1.888448] ixgbe 0000:03:00.1: Please use the pci sysfs interface instead. Ex:
[    1.888451] ixgbe 0000:03:00.1: echo '8' > /sys/bus/pci/devices/0000:03:00.1/sriov_numvfs

But this time predictable interface names dont work.
