How can I changed the default provision policy from thick to thin when creating new virtual machine?

Hi All,

In the process of "create new virtual machine" you have an option to create a disk and specify the virtual disk size and provisioning policy.

The default value is Thick provision lazy zeroed.

I want to change this default value to Thin provision, so every time someone will create new machine the default value will be Thin provision.

Anybody knows how can I do it?

Which configuration file should I change?

Thanks for your help,

Kobi
