Ah at step 1, it takes a while before the fabric server is ready. The provision status should be "success" for the root container before its ready. There is also a fabric:status command you can see if fabric is ready.
Also btw the latest release is JBoss Fuse 6.1. You may want to use that release if its possible.
And if something goes wrong, a good idea is to check the logs, you can use log:display, or log:tail etc. Or look in the log which is in the data/logs directory. Also each child container has their own logs in instances/child1/data/logs directory.
Thank you for the response.
I have updated the version to jboss-fuse-6.1.0.redhat-379.
Now all the containers have started successfully...
