Public bug reported:

When the [pci]passthrough_whitelist config contains a "remote_managed":
True device specification with a PCI address glob that matches a PF nova
should reject that as the remote managed feature is only implemented for
VFs. Nova does that eventually but with the wrong reason and strange
message. Nova tries to use the stringified PciAddressGlobSpec object as
a PCI address string when trying to query the PCI product_id of the
device. The lookup fails, as PciAddressGlobSpec is not a valid PCI
address.

I will push a reproduction test soon.
