How to saving/export VM's configuration?

I have a requirement to create a new VM(different location) using exactly the same configurations as of existing VM. I have copy of its virtual disks and so I am only interested in VM's configurations. If possible I want to store the existing VM's configurations information in my database and later use it for re-creating new VM.

I can use VirtualMachineConfigInfo data object to get all VM's configurations, but there are too many properties.

I have following questions:

  1. What are the minimum set of VM's configuration that is needed to re-create a VM ? Or do I need all the properties?

  2. Is a there way to export VM's configuration which I can use to re-create the VM later?

Thanks.
