Title:
  nova hypervisor hostname registration is not fqdn when virt-type=lxd

Status in nova-lxd package in Ubuntu:
  New

Bug description:
  While I've not picked up on any adverse effect to functionality, I'm
  raising this for the consistency factor.

  When virt-type=lxd, the hypervisor hostnames registered with nova are
  not fqdns (1, 2, 6).

  When virt-type=kvm (default), they are registered with fqdns (3, 4,
  5).

      nova-compute-kvm:
        branch: lp:charms/trusty/nova-compute
        num_units: 3
        constraints: mem=4G
        options:
          enable-live-migration: True
          enable-resize: True
          migration-auth-type: ssh
  ...
      nova-compute-lxd:
        branch: lp:charms/trusty/nova-compute
        num_units: 3
        constraints: mem=4G
        options:
          virt-type: lxd
