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,
