This bug seems to have same cause with Bug 1172643 which was closed as WON'T FIX Good catch! From Bug 1172643, it sounds like the problem is in qemu-kvm-rhev 7.0, so that's where any fix would have to be, and since pci-bridge was only tech-preview then, it's unlikely any customer would encounter it in production. I'm Cc'ing Dave Gilbert just in case his opinion has changed in the last year and a half. Yes that probably is the same as 1172643 - 7.0 had a problem with multiple PCI busses, and since bridges were tech-preview then it's a wontfix. |
