> The below snippet can fail on a host with a IPv6 loopback entry in the hosts file and MySQL is not setup to listen on the loopback interface.
> cloud-setup-databases cloud:<dbpassword>@localhost \
>                 --deploy-as=root:<password> \
>                 -e <encryption_type> \
>                 -m <management_server_key> \
>                 -k <database_key>
> The documentation could be updated to mention:
> 1) Ensure that MySQL is running on the IPv6 loopback interface ::1
> 2) OR, remove the "localhost" entry which points to "::1" from the hosts file
> [root@db01 ~]# telnet ::1 mysql
> Trying ::1...
> telnet: connect to address ::1: Connection refused
> [root@db01 ~]# telnet 127.0.0.1 mysql
> Trying 127.0.0.1...
> Connected to 127.0.0.1.
> Escape character is '^]'.
