    - sriov-1:p7p3
    - sriov-2:p7p4

The NIC configs uses NIC partitioning on p7p3 and p7p4, with VFs 0 and 1 each.

The guests are created using the below commands

openstack network create sriov1 --provider-network-type vlan --provider-physical-network sriov1 --provider-segment 502
openstack subnet create sriov1 --subnet-range 192.168.3.0/24 --network sriov1
openstack port create sriov1 --network sriov1 --vnic-type direct
sriov1_port=$(openstack port show sriov1 -c id -f value)
openstack server create --flavor m1.nfv --image rhel_nfv --nic port-id=$sriov1_port --key-name test sriov11

The guest sriov11 is in error state due to "No valid host found"

Its found that the passthrough_whitelist generated in nova.conf has the PCI addresses of the applicable VFs, their vendor id and product ids.

However we find that with physical_network details, nova could reserve a VF and the guest creation is possible.
The below configuration works and the corresponding patch shall be made in pci_passthrough_whitelist.json 

passthrough_whitelist={"physical_network":"sriov-10","trusted":"true","address":{"slot":"02","bus":"82","domain":".*","function":"0"}}
passthrough_whitelist={"physical_network":"sriov-10","trusted":"true","address":{"slot":"02","bus":"82","domain":".*","function":"1"}}
passthrough_whitelist={"physical_network":"sriov-10","trusted":"true","address":{"slot":"02","bus":"82","domain":".*","function":"2"}}
passthrough_whitelist={"physical_network":"sriov-10","trusted":"true","address":{"slot":"02","bus":"82","domain":".*","function":"3"}}
passthrough_whitelist={"physical_network":"sriov-10","trusted":"true","address":{"slot":"02","bus":"82","domain":".*","function":"4"}}
passthrough_whitelist={"physical_network":"sriov-10","trusted":"true","address":{"slot":"02","bus":"82","domain":".*","function":"5"}}
passthrough_whitelist={"physical_network":"sriov-20","trusted":"true","address":{"slot":"06","bus":"82","domain":".*","function":"0"}}
