Open Stack

Uh wait,

Is that possible it still shows available if PCI device still exist in the
same address?

Because when I remove the GPU card, I replace it to a SFP+ network card in
the same slot.
So when I type lspci the SFP+ card stay in the same address.

But it still doesn't make any sense because these two cards definitely not
a same VID:PID.
And I set the information as VID:PID in nova.conf


I'll try reproduce this issue and put a log on this list.

Thanks,
