Bug Description

With the following extract from the bundle, after the creation of the virtual functions, the VFs are not announce by nova-compute.

neutron-openvswitch:
    charm: cs:neutron-openvswitch
    num_units: 0
    bindings:
      data: *overlay-space
    options:
      worker-multiplier: *worker-multiplier
      bridge-mappings: *bridge-mappings
      prevent-arp-spoofing: True
      firewall-driver: openvswitch
      dns-servers: "8.8.8.8"
      enable-local-dhcp-and-metadata: true
      data-port: 'br-data:eno4'
      enable-sriov: True
      sriov-device-mappings: 'physnet_sriov:eno5'
      sriov-numvfs: 'eno5:8'

Only one interface is included in the extract of the bundle for brevity.

On one of the hosts:

After restarting nova-compute on the host, they are correctly announced:
