Abstract: An apparatus, method and computer program are described, the apparatus comprising processing circuitry configured to execute software, and an interface configured to receive, from the processing circuitry, a configuration request from first software requesting configuration of a virtualised device. In response to the configuration request, the interface is configured to forward a mediated request to the processing circuitry, and the mediated request comprises a request that second software having a higher privilege level than the first software determines a response to the configuration request received from the first software.
