Is it possible for you to use that version? today I finally managed to give linux kernel 3.14-rc5 a try. I was happy to discover that the bug in question has been fixed in that kernel release. In other words: with kernel 3.14-rc5 in DomU, the pci passthrough feature works again even without the 'pci=nomsi' workaround. Thanks a lot. Kind regards, jonas
