Re: 82599ES SR-IOV on Ubuntu 14.04 - VF behavior

Thanks once again for replying.

I actually had corrected the link issue prior to your response and now I know it's not the PF state.

I think this actually a number/order issue.  Is there a simple way to establish exactly what VF belongs to which PF?  Lspci or dmesg output doesn't seem to establish the connection.

In my previous examples, I used pci_0000_81_10_0, 0000_81_10_1 & 0000_81_10_2 but I am finding out that these aren't consecutive VFs of the same PF or something else has gone awry. 

What I got from looking at virsh nodedev-dumpxml is that these three addresses match to the following PFs/VFs...

Am I on the right track?
