Stupid question of the day: if I am not mistaken, I can ask nova[1] which pci/pcie devices it knows and where they are. And it will reply with the PCI address for each device it knows of. But, when I want to create flavours so I can create (libvirt-based) instances using them, I cannot tie an alias to a specific pci address; all I can do is say "this pci_alias is for all the pci devices with this vendor_id and product_id that I whitelisted already"[2]. Since libvirt allows me to feed a vm guest the exact pci device I want, could anyone point out which obvious step I am missing here?
