<p>First, connect to the cakelampvm via ssh as the developer user, e.g.: ssh
developer@cakelampvm.com </p>
<h4>Quick approach: Use the feisty meow "add_apache_site" command.</h4>
<h4>Manual approach: Edit an Apache config file</h4>

meow's "remove_apache_site".</p>

call our config file "excalibur.tv.conf". If you developed the file

<h3>Get the network address on the guest vm</h3>
<p>Run this command: ifconfig</p>
<p>In the results, look for "inet addr". There may be more than one,
if there are multiple network interfaces.</p>

<h3>How to cleanly reboot or shut down the guest VM</h3>
<p>When you've got the DNS and everything integrated, these commands will
manage the vm's state:</p>
- <p>First, log into the guest VM: ssh developer@cakelampvm.com</p>
- <p>Then, reboot the guest VM: sudo reboot</p>
- <p>Or, halt the guest VM: sudo shutdown -h now</p>
- <p>Using these commands is better than just cycling the power from the
- virtualbox control panel.</p>
