Bug Description

When OpenStack sends the command “ip link set p4p1 vf 1 state enable”, it fails.

The Error returned is : RTNETLINK answers: Operation not supported

The ip set is part of iproute2 package.

I have iproute2-3.12.0, igb 5.2.9.4, Ubuntu 14.04, kernel 3.13.0-43-generic.

The Ubuntu 14.04 LTS comes with iproute2-3.12.0, I can’t upgrade it to a newer version.

Thanks,
Dmitry

Apologies for their not being any response to your bug thus far. Unfortunately, there's not near enough information for anyone to look much deeper into your issue as have not provided detailed instructions on how to recreate your bug.

By the error surfaced, I'm guessing that the kernel you are running either does not support, or is not configured for whatever iproute needs to make this functionality work. Unfortunately, I don't know off the top of my head what that might be. If you'd like further help, you'll need to provide some detailed recreation (preferably without openstack) so that a developer might have a chance to look at the issue themselves.

As my guess is that this is a kernel support/configuration issue ultimately, you may want to just try installing a HWE kernel (HardWare Enablement) and see if that is enough to enable what you need as its significantly newer than the 3.13.0-* kernel you are on right now.

Instructions on enabling the HWE kernel for Trusty Tahr (14.04) can be seen here.
