Hi,
<div><br></div><div>Thanks for your answer Anton. </div><div><br></div><div>Actually the images we have required to fetch/enable some components while booting the instance. In order to do that, we are using some scripts. ISO contains those scripts. We have mount the iso to the image at boot time by defining it into the image
config file. </div><div><br></div><div>The bottom line is that we need to run some scripts. Can you please give me an example how do I run the scripts at the boot time in Openstack? And also where should I place those scripts? </div>
