Ans. Module will auto update the random password with all Windows VMs. For Linux (Ubuntu and Centos) we have created a cron file for reset password.
There are two reasons behind password not changing.
1. Make sure that you have entered the correct sample VM password with the configured OS under the Cloning Mapping section.
2. Have you configured the cron for reset password in your server cron job setting?
3. SSH port must be 22
To make sure your SSH connection is working fine with assigned IP. Please try to make SSH connection using assigned IP and existing VM template password.
Set Command: "*/5 * * * * php -q /yourdirectory/public_html/crons/update_vm_root_pw.php"
In WHMCS Activity Logs you can see the status of cron with specific VM.
