<div><div>Hi Hamza,</div>
<div> </div>
<div>thank you for your answere. I learnd much about the cloud-init in this process.</div>
<div> </div>
<div>I found now a way to config this without maipulating the cloud.cfg on the intance directly. I start the new instance from the copied snapshot with user-data I can inject over the "configurations" tab of a new openstack instance. I use the following config for this:</div>
<div> </div>
<div>
<pre>#cloud-config
password: <password_default_user>
chpasswd: { expire: False }
ssh_pwauth: True
preserve_hostname: True<br><br><br></pre>
</div>
<div>I think I can do some more options which may be useful, but this works fine for me by now :-)</div>
<div> </div>
<div>Kind regards,</div>
<div>Michael</div>

<div dir="ltr">Hi Michael,
<div> </div>
<div>
<div>Yes, you can comment out the modules that you don't need.</div>
<div> </div>
<div>I don't think it is a good idea to completely disable cloud-init functionality. If you do so, the instances wouldn't be able to automatically set hostnames, disk resize, SSH keys injection and more other benefits.</div>
<div> </div>
<div>If you would like to use password for authentication you need to change the property <strong>lock_passwd: True</strong> to <strong>lock_passwd: False </strong>under the section <strong>system_info</strong> in the /etc/cloud/cloud.cfg config file.</div>
<div> </div>
<div>I do not actually know what process <span style="font-size:12.8px">invokes</span> cloud-init.</div>
<div> </div>
<div>I hope the above helps.</div>
<div> </div>
<div>Regards,</div>

<div>Hi Hamza,</div>
<div> </div>
<div>thank you for your answere. So I have to comment out the modules i don't want to run when I understand this right?</div>
<div> </div>
<div>Why are the changes made to the instance when I start a snapshot of the instance and not every time when I start the instance itself? What event triggers the cloud-init to make this changes?</div>
<div> </div>
<div>What would happen when I remove the cloud-init package, will the instance still be working and what disadventages would I have then?</div>
<div> </div>
<div>Thank you and kind regards,</div>
<div>Michael</div>

<div><span>Hi all,</span></div>
<div> </div>
<div>I tried to copy instances (based on the ubuntu cloud image) from our production cloud to our test cloud according to this description</div>
<div> </div>
<div><a href="http://docs.openstack.org/user-guide/cli_use_snapshots_to_migrate_instances.html" target="_blank">http://docs.openstack.org/user-guide/cli_use_snapshots_to_migrate_instances.html</a></div>
<div> </div>
<div>but when I start the instance on the test cloud the root password ist resetet and it seems that the cloud-init is invoked and change the instance like it is the first start. Is there a way to prevent this behaviour so the instance stays unchanged when I start it on the test cloud?</div>
<div> </div>
<div>Thanks and kind regards,</div>
<div>Michael</div>
