I have tested this upgrade multiple times, from a fresh 4.4.0 —> 4.4.1. I am 
encountering a tomcat 404 error after starting CS, post-upgrade. I have 
followed the instructions provided here: 
http://cloudstack-release-notes.readthedocs.org/en/latest/upgrade/upgrade-4.4.html
 
<http://cloudstack-release-notes.readthedocs.org/en/latest/upgrade/upgrade-4.4.html>

The issue seems to be logged here (localhost.2014-11-25.log):
