Description jo4nsm1th 2012-08-21 14:14:10 UTC
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):
 kernel-3.5.2-1.fc17.x86_64

How reproducible:
 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)
  
Actual results:
pci device in domU does not work

Expected results:
pci device in domU work perfectly

Additional info:
if we boot kernel-3.3.4-5.fc17.x86_64 in xen-hypervisor then passthrough works fine

Comment 1 Konrad Rzeszutek Wilk 2012-08-30 18:58:33 UTC
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..

Comment 2 Konrad Rzeszutek Wilk 2012-09-11 11:40:48 UTC
Patch is in v3.6-rc4 and marked for stable. So it should show up in v3.5.x at some point,

Yup. Just posted a patch yesterday to fix the last of the bugs (I hope):

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