Hi,
I create VM in Vcenter7 when selecting datastore I don't have option to select disk format like Thick, Thin..
I can only check datastore, and all VM are creatings like Thick Provision Lazy Zeroed.
That's something that you configure in a later step, i.e. once the VM's settings show up. There you can expand the disk settings, and select the desired provisioning type.
