Thanks luc for quick response;
set-annotation cmd-let is slower thn setCustomValue() method. And i want it to merge this in clonevm_task.
if i use set-Annotation it will set those up after creation of VM. (correct me if i am wrong)
As cloneVM_task method is capable of customizing VMs so just want to finish this thing at that task only.
we have lot of resources in terms of Cpu RAM and bandwidth; storage can handle IPOS but yes database may be a concern where we have to look at.
