Bug description:
  Description
  ===========
  Hi guys, i ran into a problem in our POC cluster:
  At first, our cluster is configured to use ONLY metadata service
  to assist cloud init, and all KVM instances are not configureed
  with `--config-drive` opt.
  Later, for the reason of verification on how to inject metadata 
  and network configuration in pure L2 tenant network where DHCP/
  L3 services not allowed (and therefore, metadata service not ava
  -ilable either), we configured all the compute nodes with `force
  _config_drive=true` opt. Then i noticed the problems:
  a. poweroffed instances cannot poweron
  b. active instances failed to hard reboot, stuck powering-on and
     finally became error.
  After inspecting the compute log, i believe that this case is not
  taken into account when nova-compute re-generate virt XML, define
  and start instances.

  Steps to reproduce
  ==================
  1. boot new instance without `--config-drive` opt to certain compute host:
     # nova boot --flavor 512-1-1 --image cirros \
                 --nic net-id=d9897882-607a-47ba-8b28-91043a5c2d58 POC
  2. configure the compute host with `force_config_drive` opt and restart
     the nova-compute service or service container(if kolla used).
  3. shutoff the instance `POC`
     # nova stop <UUID of instance `POC`>
  4. start the instance `POC`
     # nova start <UUID of instance `POC`>
  5. hard reboot the instance `POC`
     # nova reboot --hard <UUID of instance `POC`>

  
  Expected result
  ===============
  After step4, instance `POC` will be active
  After step5, instance `POC` will be active

  Actual result
  =============
  After step4, instance `POC` stuck shutoff.
  After step5, instance `POC` is still shutoff, stuck powering-on and 
  finally became error.

  Environment
  ===========
  1. version: OpenStack Rocky + centOS7
  2. hypervisor: Libvirt + KVM
  3. storage: Ceph
  4. networking Neutron with OpenVSwitch
