Hi, what your operation in "- Add test data to config drive on vm". I create an instance with this command:
"nova boot --nic net-id=d84f5dc2-26fd-41fa-a673-b502a0d0de43 --image 7f5915c0-ffcb-489e-b706-1bd38079bd74 --flavor 36d5ae34-8668-4efb-8bc4-2c98972fc217 --config-drive true --admin-pass Fh123456 VM-1"

However, when I cold migrate the VM-1 from compute-0 to compute-1, and then lock compute-1, I locked successfully.
