I don't think I'm explicitly trying to attach to that PCI bus. As far as my limited understanding goes, I've got a vanilla virtualization configuration, where I'm running some virtio and pv drivers, but they're not attaching directly to any specific bus or device.
I'll gladly try this patch - it'll take me a bit to setup and build a custom kernel, so stay tuned, it'll probably be a few days at least before I am in a place to check it. -rb On Wed, Oct 14, 2015 at 9:33 AM, Joerg Roedel <j...@8bytes.org> wrote: > On Wed, Oct 14, 2015 at 09:05:05AM -0700, G.
