Re: Importing Vmware VCenter

In my experience, the best way to start with this kind of problem is to 
monitor the contents of /var/log/opennms/output.log

What I do is (on Ubuntu 14, so will probably be a little different on 
CentOS) is to run:
service opennms start & tail -f /var/log/opennms/output.log

This continues to produce output throughout OpenNMS's startup, and if 
there's something like a XML Parsing error (SAXParser) you'll see the 
stack traces in there. The Java stack traces can look a bit daunting, 
but you can usually discern which file it's complaining about.

If you're still stuck, I'd suggest including the output of this log in a 
reply as it may help me or someone with VMWare knowledge to see what's 
wrong.
