Dear all, Apologise, reposting this issue since the subject on the earlier thread might not be clearly depicting the problem.
I tried to perform upgrade of CloudStack version 4.1.1 to 4.2.0, and I am not able to access the CloudStack GUI after the upgrade. I am able to start the cloudstack-management service: root@cs-mgmt-01:/usr/share# service cloudstack-management start * Starting CloudStack-specific Tomcat servlet engine cloudstack-management [ OK ] However, I am not able to access the GUI with this error message: ===== HTTP Status 404 - type Status report message description The requested resource () is not available. Apache Tomcat/6.0.35 ===== I am getting this error message on /var/log/cloudstack/management/management-server.log: ===== 2013-09-23 21:36:57,003 ERROR [web.context.ContextLoader] (main:null) Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'apiDBUtils': Injection of autowired dependencies failed; ===== Full log can be found here: http://pastebin.com/0FP9itAf Any help is greatly appreciated, thank you.
