I'm not sure why this isn't valid. IMO, this equates to a wildcard. We
should test to validate this and perhaps update the docs.
> Nova should verify that devname is not an empty string and that
devname,address or product_id/vendor_id are supplied.

Title:
Nova should verify that devname in pci_passthrough_whitelist is not
empty
Status in OpenStack Compute (nova):
Invalid
Bug description:
According to
https://wiki.openstack.org/wiki/SR-IOV-Passthrough-For-Networking:
"The devname can be a valid PCI device name. The only device names that are
supported are those displayed by the Linux utility ifconfig -a and correspond
to either a PF or a VF on a vNIC"
However it's possible to supply an empty string as devname
e.g. pci_passthrough_whitelist = {"devname": "",
"physical_network":"physnet2"}
It's also possible to have an entry:
pci_passthrough_whitelist = {"physical_network":"physnet2"}
which shouldn't be valid.
Nova should verify that devname is not an empty string and that
devname,address or product_id/vendor_id are supplied.
Version
======
python-nova-2015.1.0-4.el7ost.noarch
Expected result
=============
Nova compute should fail to start when specifying an empty string for devname
when using physical_network or when not specifying devname,address or
product_id/vendor_id
