<h2>Background</h2>
<p>Some customers encountered network issues after creating private images based on our latest SLES 15 SP6 image. The problem was related to DHCP lease files not being properly cleaned up. </p>
<p>To prevent this, in addition to using <code>sysprep</code> or a custom cleanup script before creating a private image from an OTC instance, the DHCP lease information must be cleared. Otherwise, it can cause DHCP-related issues. </p>
<h2>Solution</h2>
<p>The issue was caused by leftover lease files from <code>wicked</code>. To resolve this, delete the lease files before creating an image from the instance: </p>
<pre><code class="language-bash">
ls -l /var/lib/wicked/duid.xml
ls -l /var/lib/wicked/lease*
rm /var/lib/wicked/duid.xml /var/lib/wicked/lease*</code></pre>
