I'm not sure if the issue is related to this: https://bugs.launchpad.net/nova/+bug/1333074

I was able to work around it by changing my whitelist configuration to specify the device name:

pci_passthrough_whitelist = {"devname":"ens2f0","physical_network":"physnet1"}

Where devname = port 0 of my card.

Interestingly now the port seems to get attached to a PCI address | binding:profile | {"pci_slot": "0000:07:11.6", "physical_network": "physnet1", "pci_vendor_info": "8086:10ed"} |

When I do ip link show I can see it attached to the last vf of port 0

ip link show ens2f0
5: ens2f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovs-system state UP mode     DEFAULT qlen 1000
