For virtual machines provisioned on virtual datastores, VMware provides a default No Requirements policy. You cannot edit this policy, but you can designate a newly created policy as default.

Create a storage policy compatible with Virtual Volumes.

1

Browse to the virtual datastore whose default storage policy you want to change.

2

Click the Manage tab, and click Settings.

3

Click General, and click Edit in the Default Storage Policy pane.

4

From the list of available storage policies, select a policy that you want to designate as default and click OK.

The selected storage policy becomes the default policy for the virtual datastore. vSphere assigns this policy to any virtual machine objects that you provision on the virtual datastore when no other policy is explicitly selected.
