 We review some more more common tasks with vCenter along the lines of the ones mentioned in the previous post:
To deploy an OVF:
1) first read the ovf file and get the descriptor
2) parse the descriptor to get datacenter, datastore and resource_pool
3) Create an import spec with the above parameters
4) Take an HttpNFCLease and keep it alive while posting the vmdk

To Reboot VM:
print "The current powerState is: {0}".format(VM.runtime.powerState)
TASK = VM.ResetVM_Task()
tasks.wait_for_tasks(SI, [TASK])

To Rename a VM
# rename creates a task...
task = obj.Rename(new_name)
