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".
Do you have a link to the patch adding the logic in the hypervisor? I 
will comment there as well.
Cheers,
