Abstract
A system includes a memory and a processor. The memory is in communication with the processor and configured to initialize a secure interface configured to provide access to a virtual machine (VM) from a device, where the VM is associated with a level of security. A buffer is allocated and associated with the secure interface, where the level of security of the VM indicates whether the device has access to guest memory of the VM via the buffer. The buffer is then provided to the device. Inputs/outputs (I/Os) are sent between the device and the VM using the secure interface.
