It has been a year and a half since I posted my blog on how to configure SR-IOV on Red Hat 5.4 Xen for the Intel® 82576 GbE Controller.  A lot has changed since then – we now have four Ethernet Controllers that support SR-IOV:

 

1Gb Ethernet – 8 VFs per Port

  • Intel® 82576EB Gigabit Ethernet Controllers
  • Intel® Ethernet Controller I350

10Gb Ethernet – 64 VFs per Port

  • Intel® 82599 10 Gigabit Ethernet Controllers
  • Intel® Ethernet Controller 10Gb  X540

 

Another change is that I am no longer the TME (Technical Marketing Engineer) for Intel Ethernet Virtualization (though I am still helping out with the blogs).  The new TME, Waseem, has just published a very good technical brief that details how to make use of SR-IOV using Linux KVM, which is an integral part of Red Hat Enterprise Linux version 6 and 6.1, it is available here.

 

There are lots of great pictures and explanations, so go give it a read today!  Again the doc is located at:
