Abstract
Systems, methods, and computer program products to perform an operation comprising executing a device driver in a private logical partition on a compute host, wherein the device driver is configured to execute in an environment different than an environment of a hypervisor of the compute host, establishing a communication channel between the private logical partition and an adjunct partition executing on the compute host, and configuring, responsive to a command sent by the adjunct partition to the device driver via the communication channel, a physical function of a single root I/O virtualization (SR-IOV) device of the host system.
