Hello

Is this a regression? Does it work on previous versions of Xen?

"xl -vvv pci-attch" can provide more insight.

From the screenshot I can see the VF does show up in the guest, so the
xl command probably runs fine.

(A side note, please be considerate to xen-devel subscribers who might
not have large bandwidth or an image viewer -- avoid sending pictures in
the future.)

Maybe have a look at xl dmesg to see if there is anything interesting
there?
