Abstract

Techniques for memory assignment for guest operating systems are disclosed herein. In one embodiment, a method includes generating a license blob containing data representing a product key copied from a record of license information in the host storage upon receiving a user request to launch an application in the guest operating system. The method also includes storing the generated license blob in a random memory location accessible by the guest operating system. The guest operating system can then query the license blob for permission to launch the application and launching the application in the guest operating system without having a separate product key for the guest operating system.
