Comment 18 for bug 1347715

To reproduce, with current trunk:

1. Have an instance ready somewhere (e.g. EC2) to use with the manual provider.

2. include "logging-config: <root>=DEBUG" in the environment section in environments.yaml. Mine looked like:

  manual-ec2:
    type: manual
    bootstrap-host: blah-blah.us-west-2.compute.amazonaws.com
    bootstrap-user: ubuntu
    logging-config: <root>=DEBUG

- juju bootstrap --upload-tools

SSH to the bootstrap node and you'll see a panic along the lines of:

panic: interface conversion: interface is float64, not int

goroutine 160 [running]:

Somehow the storage port is ending up a float where an int is expected. There are tests around this but they obviously don't cover this case. I haven't figured out how the float value makes it in.

I will attach the full machine-0.log.
