</li><li style><span style="font-family:arial,sans-serif">So again per your blog I changed all of the 10.0.3 to 10.0.4 subnet in /etc/default/lxc</span><br></li><li style><span style="font-family:arial,sans-serif">Restarted LXC</span><br>
</li><li style><span style="font-family:arial,sans-serif">then finally </span><br></li><li style><span style="font-family:arial,sans-serif">created a "child-container" </span><br></li><li style><span style="font-family:arial,sans-serif">started the "child-container"</span><br>

<div style><font face="arial, sans-serif"><br></font></div><div style><font face="arial, sans-serif">However... my question now ... if you wanted to create multiple "child-containers" </font></div><div style><font face="arial, sans-serif"><br>
</font></div><div style><font face="arial, sans-serif">Do you have to re-edit the /etc/default/lxc file and manually change the IP network/subnet each time ... </font></div><div style><font face="arial, sans-serif">or is there a way to have it automated so each new "child-contianer" is allocated a good Network/Subnet as its created?</font></div>
<div style><br></div><div style><font face="arial, sans-serif">If someone wanted to create say 20-30 child-containers... this would become tedious and error prone to do manually.</font></div><div style><font face="arial, sans-serif"><br>
