Closing this because our expectation here is that neutron and libvirt should detect the same hostname.
I've reported another bug to fix current incompatibility.

Title:
  Overriding hypervisor name for resource provider always requires a
  complete list of interfaces/bridges

Status in neutron:
  Invalid

Bug description:
  In some deployments, hostnames can be different between hosts and resource provider records. For example in deployment managed by TripleO we use short host name (without domain name) in host, while we use FQDN for resource provider records (this comes from the FQDN set to the host
  option in nova.conf).

  This causes an issue with the way how currently neutron looks up the
  root resource provider because placment API requires the exact
  hostname and doesn't automatically translate short name and FQDN.

  To fix the issue we need to set the resource_provider_hypervisors
  option[1] now but it is very redundant to list up all devices or
  bridges in this option to override hostnames for the devices/bridges
  by the same value.
