摘要： Examples described herein include systems and methods for fuzz testing low-level virtual devices and virtual devices with DMA write functionality. A fuzz tester includes components distributed across a virtual machine and its host system. The fuzz testing components in the virtual machine are implemented as firmware installed in the virtual machine's ROM. These components operate independent of data stored in the virtual machine's RAM and do not require an operating system to be installed on the virtual machine. As a result, any changes made to the virtual machine's RAM during the fuzzing process by low-level virtual devices or virtual devices with DMA write functionality cannot interrupt the fuzz testing or otherwise negatively impact the fuzz tester itself.

摘要： In one embodiment, a computer system provides a process for executing software that cannot be executed in a first configuration. The computer system determines source media for the software stored in a first data store, the source media being in the first configuration. The computer system retrieves metadata relating to executing the software from the source media. The computer system next transforms the retrieved metadata to generate a second configuration of the source media according to a transformation rule set, where the software can be executed in the second configuration, and stores the transformed metadata in a second data store. Next, the computer system presents the second configuration of the source media based on the transformed metadata. Thereafter, the computer system satisfies a request relating to executing the software using the transformed metadata in the second data store, wherein the request is satisfied based on the second configuration.
