Toolstack needs to get this information to know which BDFs are free and can be used by virtio-pci.It sounds a bit odd to let the hypervisor to assign the BDFs. At least because there might be case where you want to specific vBDF (for instance this is the case with some intel graphic cards). This should be the toolstack job to say "I want to assign the pBDF to this vBDF".Keep in mind we are also supporting dom0less PCI passthrough. You could have logic for assigning the BDF automagically. But that should be part of dom0less, not deep into the vPCI code. Cheers, -- Julien Grall
