Title:
  nova resize-revert forgets hw_cdrom_bus

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Hi,

  The test
  tempest.api.compute.servers.test_server_actions.ServerActionsTestJSON.test_resize_server_revert
  fails for me on arm64.  It turns out that this is because (if you use
  a config drive, which is the default with devstack) you need to set
  hw_cdrom_bus on the image to 'virtio' but the resize-revert command
  somehow fails to take this into account and tries to put the cdrom on
  the ide bus, which does not exist in the emulated machine model on
  arm64.

  These command reproduce for me (given an image with hw_cdrom_bus set)

  nova boot --poll --image $IMAGE_ID --flavor m1.tiny inst
  nova resize inst m1.small --poll
  nova resize-revert inst

  I'll attach the libvirt log for such an instance.
