This week Ubuntu launched their 15.10 Wily Werewolf on October 22, 2015. This release had some great updates for server users such as LX-D and Autopilot OpenStack deployments to name a few upgrades. Under the hood, there is a big change for Intel Xeon D-1540 users: native drivers! We installed the latest release on an Intel Xeon D-1540 machine (Supermicro X10SDV-4C-TLN2F) that was being wiped and we were pleasantly surprised to see something quite different than with Ubuntu 15.04: network interfaces that showed up!
The impact is that for users of motherboards like the Supermicro X10SDV-4C-TLN2F we reviewed, this makes installation significantly easier. Of course, 15.10 has relatively short release support, but this is a major upgrade. It means that Intel Xeon D users can use 10Gbase-T networking out of the box.
Ubuntu has been one of our most utilized OSes simply because of the lack of SR-IOV support with the current Intel Xeon D series. We saw a few more Intel Xeon D motherboards on our trip to Taiwan this week. Rest assured, more are coming.

Would you mind posting in a reply to the below post a link to a pastebin of the output of the below commands run on that host?

Uh, no. That’s close to just the second. Maybe someone else can help.

It’s perhaps worth updating this post at some point to clarify that SR-IOV can work on this platform (the above is somewhat ambiguous).
Also one might mention that the driver (ixgbe module) for the X557 is upstream in the Linux kernel since v4.1.
Thanks!
