Abstract
Virtualization is a promising technology for running multiple operating
systems (OS's) on a single processor. Preparing an OS for use with
virtualization, however, involves making some changes to the OS code, which
must be repeated for each version, whether a new release or a client
customization. Typically such changes are expressed as patches, but
patches are often not portable from one version to another, and thus manual
adjustments are needed as well. In this paper, we consider the use of the
automated transformation system Coccinelle to perform the changes required
to port several versions of Linux to the VLX hypervisor. Coccinelle
provides a notion of semantic patches, which are more abstract than
standard patches, and thus are potentially applicable to a wider range of
OS versions. We have applied this approach in the context of Linux
versions 2.6.13, 2.6.14, and 2.6.15, for the ARM architecture.
