Abstract
Secure drivers for confidential virtual machines. A communication channel is established by a first device driver executing in a memory of a virtual machine manager (VMM) with a second device driver executing in a private memory of a user space memory of a confidential virtual machine that was initiated by the VMM. The private memory is inaccessible by the VMM. The first device driver provides the data over the communication channel to the second device driver within the user space memory. The second device driver receives the data. The second device driver modifies the private memory to include the data or prevents the data from being written to the private memory based on a criterion.
