1. A computer-implemented method comprising: loading, at a computing device, a process into a virtual machine operating under control of a hypervisor communicatively interfaced with a host operating system kernel of a host operating system of the computing device, the hypervisor executing under control of the host operating system; exposing, at the computing device, a subset of an Application Programming Interface (API) to the virtual machine, wherein the process interfaces with the host operating system kernel via the subset of the API; and executing the process in the virtual machine.
