Comment 17 for bug 1821026

@Peng Peng
Here is my operation, but I can not reproduce your problem:
1. careat an VM:
nova boot --nic net-id=d84f5dc2-26fd-41fa-a673-b502a0d0de43 --image adcca643-ba09-437a-a966-9d486bcb782c --flavor 36d5ae34-8668-4efb-8bc4-2c98972fc217 --config-drive true --admin-pass Fh123456 --user-data test.config xiexie-5
and this is mu test.config:
chpasswd:
    list: |
        root:rootroot
        centos:centos
    expire: false
ssh_pwauth: yes

hostname: xiexie

resolv_conf:
    nameservers: ['8.8.8.8']
    searchdomains:
        - localdomain
    domain: localdomain
    options:
        rotate: true
        timeout: 1
manage_resolv_conf: true

packages:
    - vim
    - wget
    - httpd

timezone: 'Asia/Shanghai'

runcmd:
    - [ sed, -i, "s/^ *SELINUX=enforcing/SELINUX=disabled/g", /etc/selinux/config ]
    - [ mkdir, /dropme ]
    - [ touch, /root/abc.txt ]

power_state:
    delay: now
    mode: reboot
    message: reboot now
    timeout: 30
    condition: true
2. migrate the VM from compute-0 to compute-1
3. then lock compute-1
4. Lock successfully

And my ISO is 20190630....
Is my operation different from yours.
