Title:
  reboot-instances fails after nova-compute process reboot

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  when the nova-compute process is rebooted, there may be  some
  instances at the current host in the rebooting process.

  we know that if  instances' task_states are in the reboot_pending and  reboot_pending_hard statuses,these instances will reboot after the nova-compute process is rebooted.
  But, these instances fail due to the reboot operation using the rpc call, because the rpc call can fail due to the network impact.

  There is no need  using the rpc call  to reboot the instances, because the rebooted instances are just at the current host.
  This way not only reduces the possibility of reboot failure but also keep paces with the other operation after the nova-compute process reboots.
