Problems using vfio pcie passthrough (pci-assign works)

[Bruce Cran <bruce@cran.org.uk>]

I have a PCIe card that's behind an Intel E3-1200 PCIe x16 controller 
bridge that I want to use in VMs: it works when using the pci-assign 
driver, but something goes wrong when trying to use vfio-pci - my driver 
in the guest gets so far through loading before failing to talk to the 
hardware, so I guess something's not being setup correctly.  I'm 
wondering if this is a bug (do vfio and OVMF work together?) or a 
problem with the way I'm setting up vfio-pci. I'm using the script from 
http://www.linux-kvm.org/wiki/images/b/b4/2012-forum-VFIO.pdf page 30 to 
assign the card, but I know it's a fairly old document, and I'm running 
kernel 3.11 on openSUSE: is it still correct?   Or should I not try to 
use vfio-pci for now?
