Comment 1 for bug 1954546

I had the same issue: Instances took IP, but not hostname and key pair. The error in instances logs:

    checking http://169.254.169.254/2009-04-04/instance-id
    failed 1/20: up 0.78. request failed
    failed 2/20: up 12.78. request failed
    failed 3/20: up 24.79. request failed
    ...

It got solved by adding `--config-drive true` to the server creation command, or, `force_config_drive = true` into the nova.conf file on the compute node.
