I have created a trove image, both manually and using the instructions using the DIB, its Maria DB 10.1.20 on CentOS 7. As far as troubleshooting is concerned

• Trove task manager is creating the file and Injecting - Check
• Nova instance is booted using a cinder volume and also the correct security group - Check

For troubleshooting, I created a backdoor in the image so that I could check. When I see, the guest agent logs I get the error. I am running
