This is a description of how to create a Single System Image (SSI)
cluster of virtual User-Mode Linux (UML) machines. After explaining
how to use the pre-built SSI/UML binaries, this document demonstrates
what an SSI cluster can do. Then it shows more advanced users
how to build their own SSI/UML kernels, ramdisks and root images.
Following that, it provides an overview of how to move to a
hardware-based SSI cluster. It concludes with a set of links
and an invitation to contribute to the SSI Clustering project.
