Description of problem:
Xen PCI Passthrough does not work on kernel-3.5.2-1.fc17.x86_64
Version-Release number of selected component (if applicable):
hardware requirements: system with vt-d support ( INTEL Core i7 2600 on INTEL DQ67SW for me)
Steps to Reproduce:
1. install fedora 17
2. Update system and install Xen
3. Boot fedora 17 (kernel-3.5.2-1.fc17.x86_64) in xen-hypervisor
4. install domU system (Windows XP proffessional for me)
5. try to passthrough pci device (onboard usb controller for me)
pci device in domU does not work
pci device in domU work perfectly
if we boot kernel-3.3.4-5.fc17.x86_64 in xen-hypervisor then passthrough works fine
Yup. The problem is that a patch in v3.5 causes MSI's to not be enabled for HVM PCI passthrough anymore. Working on it..
Patch is in v3.6-rc4 and marked for stable. So it should show up in v3.5.x at some point,
kernel-3.5.4-1.fc17.x86_64 out but bug still not fixed.

Works for me.
This is in the stable repo. Not sure why bodhi didn't close the bug.
