Abstract :
This paper discusses the implementation of a new hypervisor mechanism for loading dynamic shared objects (modules) at runtime. These loadable hypervisor modules (LHM) are modeled after the loadable kernel modules used in Linux. We detail the current LHM implementation based on the Xen hypervisor. Potential use cases for this LHM mechanism include dynamic hypervisor instrumentation for debug tracing or performance analysis. We discuss the initial LHM prototype and future plans.
