allow pci alias choose subset of devices

Registered by Yongli He

whitelist might select subset of devices define as 'available' and left devices is none allocatable, but we need a way to choose a subset device to allocated to VM, and keep all pci devices available for other purposes.

for example:

Say have 4 10G pci cards( so vendor id and product id are same) and if 2 are connected to one network and other 2 to another switch, i need a way to allocate a VM with 1 mic from each group. I think this is currently not possible in Kilo.
