I am trying to setup pci-passthrough to my domU. I am able to pass through of my USB controller, but I cannot pass through my RAID bus controllers. Here are the pci devices in question:
Code:
00:07.2 USB Controller: Intel Corporation 82371AB/EB/MB PIIX4 USB (rev 01)
...
00:0d.0 RAID bus controller: Silicon Image, Inc. SiI 3124 PCI-X Serial ATA Controller (rev 01)
00:0e.0 RAID bus controller: Silicon Image, Inc. SiI 3124 PCI-X Serial ATA Controller (rev 01)
I believe that I have pci-passthrough setup correctly because I am able to pass the USB controller through. However, if I try to add one or both of the RAID controllers, my domU fails to boot. Here is what I think is relevant xend.log output on a failure:
Code:
