Identify VM from command line?

Hi all,

Does anyone know if it's possible to find the vCloud ID of a VM from the VM itself?

We are trying to create a script for vFabric App Director, that allows the user to add a disk to the VM during deployment (we don't want to lots of different VM templates...)

The plan is that the script will run inside the VM once it's been deployed.

I'm fairly comfortable with the API REST code to add a drive to the VM, but I can't see a way to get the ID of the VM from the VM's console. (We're using Linux here)

Can anyone advise?

Thanks,
Alex
