host creation failed and Firebug raises 500 ISE

Description of problem:
I was trying to create a new host via UI and filled the form with all necessary info. But when I submit the form the firebug raised following error:

"NetworkError: 500 Internal Server Error - https://dhcp207-190.lab.eng.pnq.redhat.com/hosts/shost.katellolabs.org/vm"
vm
ReferenceError: _ is not defined

snippet from production.log 
============================
Processing by HostsController#vm as HTML
  Parameters: {"id"=>"shost.katellolabs.org"}
Operation FAILED: can't convert nil into String
  Rendered common/500.html.erb (10.2ms)
Completed 500 Internal Server Error in 46ms (Views: 15.4ms | ActiveRecord: 3.8ms)


Version-Release number of selected component (if applicable):
sat6 beta snap10 compose3

How reproducible:
tried once

Steps to Reproduce:
1. created new hostgroup and selected activation-key
2. filled up "New Host" form first with hostgroup and then unselect it
3. Filled all other details and submit the form

Actual results:

  Rendered common/500.html.erb (10.2ms)

Expected results:

Comment 3 Dominic Cleal 2014-06-25 09:38:21 UTC 
Please edit ~foreman/config/environments/production.rb and uncomment "config.log_level = :debug", run "service foreman restart" and retry to get a stack trace in the logs.

1. What type of compute resource are you provisioning onto?
2. If you visit the host page again, does it load correctly with power state?  i.e. is the bug only after initial provisioning
Comment 4 Sachin Ghai 2014-06-25 09:43:53 UTC 
Looks like this issue is related to bz #1113012. As I stated in steps to reproduce, first I selected the hostgroup and then unselected. So looks like it was not unselected actually with empty row. 

I tried again with new host creation and without touching hostgroup dropdown. This time provisioning kicked off.
Comment 5 Sachin Ghai 2014-06-25 09:44:48 UTC 
I'll share the requested info in comment3 in few minutes.

Please see attachment for traceback.

Libvirt

On loading, All hosts page and selecting the failed VM, the state still shows "Loading Power state.." However, I can define a New Host

Comment 9 Dominic Cleal 2014-06-25 10:14:35 UTC 
Could you provide the log including host creation?  This is only a partial bit.

Is the VM actually running?  I suspect it wasn't created.
Comment 10 Sachin Ghai 2014-06-25 10:27:51 UTC 
I tried to check via virt-manager and it wasn't created. However UI shows its entry under "All hosts" with "Loading Power state..".

I'll try to re-create this issue and share the logs with host creation.
Comment 11 Sachin Ghai 2014-06-25 10:55:07 UTC 
I can recreate the issue with following steps.

- Go to New Host page (Make sure one hostgroup already created)
- select hostgroup from drop down
- fill all details in form, I choose 'libvirt' compute resource
- de-select the selected hostgroup
- submit form


Going to attach complete logs with host_create in next comment.

Comment 13 Dominic Cleal 2014-06-25 11:23:46 UTC 
There are a couple of odd things in both the latest log file and particularly the foreman-debug archive.  Are you getting an error when submitting the host, and then retrying?

The foreman-debug archive indicates a host creation that first fails with:

"Fetch TFTP boot files for shost.katellolabs.org task failed with the following error: invalid medium for RedHat 6.5"

And then a second attempt, which probably due to a bug in the form, is without the attributes required to create a new VM (I'd guess the "Virtual Machine" tab isn't visible when the form reloads).

(As a note to myself, validation of medium applicability to an OS should happen earlier too.)

Yes, initially when I deselected the hostgroup and submitted the form, I got following error. Since the Medium text box does not populated on UI when we select hostgroup, So when we unselect it, UI doesn't populate medium text box, it appears only on form submation and after below error.

Fetch TFTP boot files for shost1.katellolabs.org task failed with the following error: invalid medium for RedHat 6.5

Thanks for all of the logs and detail, that was a big help.

Note that the associated redmine is a tracker for two separate issues that are relevant here.
