.. py:method:: EC2.Client.modify_vpc_tenancy(**kwargs)

  

  Modifies the instance tenancy attribute of the specified VPC. You can change the instance tenancy attribute of a VPC to ``default`` only. You cannot change the instance tenancy attribute to ``dedicated``.

   

  After you modify the tenancy of the VPC, any new instances that you launch into the VPC have a tenancy of ``default``, unless you specify otherwise during launch. The tenancy of any existing instances in the VPC is not affected.

   

  For more information, see `Dedicated Instances <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/dedicated-instance.html>`__ in the *Amazon EC2 User Guide*.
