Open Stack

This post is probably not helpful and very much in the vein of nay saying.  However, my experience with sr-iov and the experience others have shared with me invoke me to caution you.  I have never heard of a successful execution of sr-iov with openstack.  I have personally seen some of the abject strangest hardware failures I have had the misfortunes of experiencing with it. 

Good luck. But I fear that in the choose your own adventure game of cloud you may have trodden upon a bad end.
