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.
