Hi,
Unfortunately there are times as you can see here where the log doen't provide much help.
If you look in all the logs under /opt/vmware/www/build/<yourpofile.instance>/status such as the verbose and debug logs you might find something more useful.
Some additional places to look that hopefully might help:
- Additional logs under /opt/vmware/var/log/*
- The standard log directory /var/log
- View the console of the vm being built and cycle through the terminals ALT+F1-F6.
