Subject: Problems using vfio pcie passthrough (pci-assign works)
Date: Thu, 02 Oct 2014 07:39:48 -0600 [thread overview]
Message-ID: <542D55A4.6000005@cran.org.uk> (raw)
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?
