Without this patch there are some niggling whitespace and formatting
issues introduced by this pull request and change set.
This patch cleans those up and makes git log --check look nice again.
Without this patch, the test for the vSphere linked clone option to the
vm_clone request throws an exception. For the full exception please see
GH-697 discussion comments on Github at [1]
This patch fixes the issue by removing the cleanup code which is not
necessary for a Mocked test. The cleanup code was calling a method on
the response_linked object which is not actually in scope.

The behavior without this patch is that the performance of the vm_clone
operation in unacceptably slow for VMware vCenter deployments with
multiple hundreds of virtual machines.
Performance is unacceptable because the vm_clone operation makes
multiple API calls to list _all_ of the VM's in the inventory. This
patch eliminates the need to list all VM's by adding path and folder
filters to limit our API calls to subtrees of the VMware inventory.
= API Changes =
* New datacenters request that caches the Datacenter objects for the
life of the process.
* New clone() method on the server model that returns a server model of
the new VM even if it is not yet done cloning.
* Ability to limit collections to inventory paths by passing the
* 'folder' filter to the servers collection. For example:
`conn = Fog::Compute[:vsphere];
conn.servers('path' => '/Datacenters/DC1/vm/Templates')`
this filter will greatly reduce the number of SOAP API calls by
limiting the server models in the collection to only those in the
Templates inventory folder. Note, this is not recursive yet.
= Tests =
Tests have been updated. The vm_clone request no longer takes an
instance_uuid because we cannot actually use this to search the
inventory efficiently. Instead, the vm_clone request now requires a
path attribute to allow Fog to search only a subset of the inventory.
Update `Fog::Compute::Vsphere` tests to reflect the way the
`Fog::Compute::Vsphere#convert_vm_mob_ref_to_attr_hash` method currently
converts a `RbVmomi::VIM::ManagedObject` object to a hash.
Without this patch, tests related to converting an instance of
`RbVmomi::VIM::ManagedObject` to a hash will raise an exception:
NoMethodError: undefined method `collect!' for Hash; causing the test to
fail.
This patch solves the problem by mocking `RbVmomi::VIM::ManagedObject`
with a new `MockManagedObject` class, which provides a `collect!`
method, and the `_ref` and `parent` attributes.
This patch renames fake_vm to fake_vm_mob_ref in order to provide a
more descriptive name for what's actually being tested.
The `Fog::Compute::Vshpere::Mock` class has been updated to require the
rbvmomi library, which prevents an `NameError` exception from being raised
due to the `Fog::Compute::Vsphere::Shared::RbVmomi` constant not being
initialized.
The `Fog::Compute::Vshpere::Mock` class has been updated with a
`get_folder_path` method, which prevents a `NoMethodError` exception
from being raised due to the `get_folder_path` method being undefined.
This patch adds a new `path` attribute to the vm_mob_ref hash returned
by the `convert_vm_mob_ref_to_attr_hash` method. In order to support the
new `path` attribute, this patch also adds a new `get_folder_path` method
to the `list_virtual_machines` vsphere module.
This patch changes how the `list_all_virtual_machine_mobs` method
searches for virtual machines. Previously the search was based on
children of the `dc.vmFolder` object. This makes the false assumption
that all children are virtual machines.
Now the search is based on the entire inventory of the `dc.vmFolder`
object, which gives us more control over what we consider a virtual
machine.
This patch also adds a new `find_all_in_inventory` method; a generic
method that can be used to search an inventory for any VMware object
exposed by RbVmomi. Using `find_all_in_inventory` we are able to
traverse VMware folders and pickout specific VMware object, in this case
`RbVmomi::VIM::VirtualMachine`
Without this patch the vm_clone requiest would not find a Managed Object
Reference when a UUID that is not a string is passed as the
instance_uuid option. This is a problem because an unhelpful "undefined
method `parent' for nil:NilClass" would be thrown to the application.
This patch throws a more helpful Fog::Compute::Vsphere::NotFound
exception if the Virtual Machine template is not found.
The tests have been updated to reflect this expectation.
This massive commit refactors all of the request methods on the
Fog::Compute[:vsphere] instance to return simple hashes. The behavior
before this commit returned full vmware object references which was a
problem because it was difficult to unit test.
With this patch, it is much easier to add and maintain Mock
implementations of the request methods. This makes adding behavior
tests for the server model much easier.
In addition, test coverage using Shindo has been added. Previously
there was little test coverage of the behavior.
To run the tests:

Without this patch it is very difficult to reload the model of a VM in
the process of being cloned. All we have is the vmware managed object
reference ID string and the name of the VM.
This patch adds a number of improvements:
First, the model of a VM being cloned can reload itself after the VM
finishes cloning, even though we don't have an instance_uuid until the
clone completes.
Because the model can reload itself, it's now possible to do something
like:
c = Fog::Compute[:vsphere]
new_vm_name = "test"
c.vm_clone(:instance_uuid => "abc123", :name => new_vm_name)
my_new_vm = c.servers.find { |vm| vm.name == new_vm_name }
my_new_vm.wait_for { uuid }
puts "New VM is ready! (It has a UUID)"
my_new_vm.wait_for { ipaddress }
puts "New VM is on the network!"
Without this patch, a VM model could not reload itself with an id of
'vm-123', reloading the model only works if the ID is a UUID.
In addition, a number of the attributes of the server model have been
adjusted to be nil values when the VM is in the process of cloning.
This makes it easier to use wait_for conditionals in blocks.
Without this patch we have no way to clone a new VM
from a template. This patch adds the vm_clone request
which takes an instance uuid as the source template
to clone from an a name parameter which is the new VM's
name.
The clone operation is handled asynchronously as a vSphere
task object. The clone request does not return a handle
for this task, which may make it difficult to monitor
the progress of the clone operation from Fog. A future
enhancement may be to clone and return the task object
itself to monitor progress.
Without this patch we did not have a convenient way to find
a template by instance UUID. We could only find virtual
machines by instance UUID, which may or may not be a template.
This patch adds a specific request to obtain the VMware managed
object instance of of a specific template. This is necessary
plumbing for the clone request.
Without this patch we have no way to completely destroy
a server instance. This patch adds a vm_destroy API request
and implements the destroy method on the server model.
The vSphere API requires the server to be in a poweredOff state.
The model action and the request do not verify this is the case
before issuing the command.
This patch implements the start, stop and reboot methods for the Server
model instances.
These server model methods share common names with the AWS server model.
This patch also implements the API requests required to control the
power state of a VMware Virtual Machine.
The requests default to issuing shutdown and reboot commands to the
guest operating system itself. However, if force is set to true for
power_off and reboot, then the VM is powered off or reset at the virtual
hardware layer.
This patch adds two request methods to the compute service for VMware.
First, finding a VM by it's own UUID (from the vmx file) is supported.
This UUID is not guaranteed to be unique so this patch also implements
finding by instance UUID which is guaranteed to be unique.
The server models will primarily use these requests to obtain VM
managed objects to issue commands against.
This patch adds a request list_virtual_machines which is responsible for
making an API connection and returning a raw "response" object from the
API.
Model instances of a Server (compute resource) are returned as a
collection through the "all" method. The Fog framework calls all on the
instance of the collection.
Without this patch, no actual API calls are being made through the Fog
layer to the underlying rbvmobi later and ultimately to the vSphere
target API.
This patch adds a simple current_time request which is similar to a
"ping" The layers and API are exercised fully using this simple API
call to retrieve the current time on the remote system.
This provides:
