  8. Add the following statement after - final-message in cloud_final_modules:

    - power-state-change
    
  9. Check and modify the information in system info to make it consistent with the following content:

    system_info:
       default_user:
          name: linux  //Username for OS login
          lock_passwd: True   //True indicates that login using a password is disabled. Note that some OSs use value 1 to disable the password login.
         gecos: redhat
         groups: [audio, cdrom, dialout, floppy]   // (optional) Add the user to other groups that have been configured in etc/group.
          sudo: ["ALL=(ALL) NOPASSWD:ALL"]  //Current user has all the root rights.
          shell: /bin/bash   //Execute shell in bash mode.
       distro: sles
        paths:
          cloud_dir: /var/lib/cloud/
          templates_dir: /etc/cloud/templates/
          upstart_dir: /etc/init/
        ssh_svcname: sshd
    

    In the preceding command, change the value of distro based on the OS, such as distro: sles, distro: rhel, distro: ubuntu, distro: debian, and dustro: fedora.

  10. (Optional) For Ubuntu 14.04, perform the following operations:

    1. Use the vi editor to open the /etc/init/cloud-init-local.conf configuration file and modify the following configuration items:

      # cloud-init - the initial cloud-init job
      #   crawls metadata service, emits cloud-config
      start on mounted MOUNTPOINT=/ and mounted MOUNTPOINT=/run and stopped bms-network_config
      
    2. Run the following commands to configure the OpenStack source:

      dpkg-reconfigure cloud-init

      image1

      Run the vim /etc/cloud/cloud.cfg.d/90_dpkg.cfg command to open the configuration file and check whether the items are correctly configured in the file.

      # to update this file, run dpkg-reconfigure cloud-init
      datasource_list: [ OpenStack ]
      ~
      ~
      ~
      

      If the configuration file content is consistent with the preceding command output, the configuration is successful.
