Comment 2 for bug 1808738

you might be able to filter out these message by appending
nova.pci.utils=ERROR to the default set of log level and defined for this config option
https://docs.openstack.org/nova/latest/configuration/config.html#DEFAULT.default_log_levels

not this warning is expected if the vf is bound to the vfio-pci dirver as the vf does not have a corresponding netdev.

the only side effect of not haveing a netdev is we cannot discover the nic feature flags.
 currently we dont use them for anything as the code to discover them and store the min the database
merged but the code to schedule on them never did so this should not cause any issues im aware of.
