Hi, Henry:

Appreciate very much for your kind reply!

Yes, this is what I want, however, I am not seeing the detailed error message as you are seeing.

I am still using OpenStack Icehouse, are you using OpenStack Juno or Icehouse?

[root@openstack-03 heat(keystone_admin)]# heat stack-show LCH_test1

The deployment resource has attributes deploy_status_code, deploy_stderr and deploy_stdout [1]. Currently you will need to create stack outputs in your template to expose these properties then use heat stack-show to see their values.

There are blueprints for Kilo which will make it possible to access these values in different ways without having to modify your heat template [2].
