Abstract
Secure and efficient access to host memory for guests is disclosed. For example, a system includes (i) a processor, (ii) a host memory, (iii) a hypervisor including a filesystem daemon, (iv) a guest including a storage controller, and (v) a first filesystem queue. The storage controller is configured to receive a file request, translate the file request, and add the translated file request to a filesystem queue. The filesystem daemon is configured to retrieve the translated file request from the filesystem queue and provide access to a file in the host memory identified in the file request to the guest.
