Cause

When you create a new clustered service or application, a computer object (computer account) for that clustered service or application must be created in the Active Directory domain.

This computer object is created by the computer object of the cluster itself.  This computer abject of the cluster is responsible for creating the computer object for  "SQL Virtual Server" in active directory . If the computer object of the cluster itself does not have the appropriate permissions, it cannot create or update the computer object for "SQL Virtual Server"  . So the installtion of SQLServer would fail.

To resolve this issue Grant  "Create Computer Objects" permission for  the computer object created for the cluster  (Computer Name object(CNO)).
