From Kilo on I have not been able to set Yes to configure vmware backend without it failing. Set to no and enter the rest of the vmware info and it runs through just fine. Then after some config change I can connect to the vcenter / storage but get a device 0 error. So I am wondering what exactly does "Configure vmware backend" do??? Is there a subset of script that are ran and if so which ones?

Packstack uses the nova module from the OpenStack Puppet Modules project, the nova::compute::vmware class sets the vmware configuration directives in the nova configuration file:

nova_config {
    'DEFAULT/compute_driver':     value => $compute_driver;
    'VMWARE/host_ip':             value => $host_ip;
    'VMWARE/host_username':       value => $host_username;
    'VMWARE/host_password':       value => $host_password;
    'VMWARE/cluster_name':        value => $cluster_name;
    'VMWARE/api_retry_count' :    value => $api_retry_count;
    'VMWARE/maximum_objects' :    value => $maximum_objects;
    'VMWARE/task_poll_interval' : value => $task_poll_interval;
    'VMWARE/use_linked_clone':    value => $use_linked_clone;
  } (

Here's how packstack uses it:

class { '::nova::compute::vmware':
  host_ip       => hiera('CONFIG_VCENTER_HOST'),
  host_username => hiera('CONFIG_VCENTER_USER'),
  host_password => hiera('CONFIG_VCENTER_PASSWORD'),
  cluster_name  => $nova_vcenter_cluster_name,
} (

Since packstack sets only the values above, the module uses it's default values:

  $api_retry_count = 5,
  $maximum_objects = 100,
  $task_poll_interval = 5.0,
  $use_linked_clone = true,
  $wsdl_location = undef,
  $compute_driver = 'vmwareapi.VMwareVCDriver'

I hope this helps

Thank You!! Very well written and detailed!
That's pretty much what I could find but was unsure if packstack was in-fact configuring other items I could not see. Again thank you for this!!!

is there any kind of mapping to what the YES setting does?

I am using vsphere hypervisors exclusively, 5.5, and am well versed in the VMDK Driver. Just need to know what this particular setting is doing so I can possibly correct it.
