Massive Virtualization on IBM Power5 System
The authors built a system with 80 concurrent Linux images running on a single 8-way system. There are a number of interesting issues, including how the system was configured, and tricks for simplifying administration. You certainly don't want to run through the installer 80 times. This paper will discuss how a massively virtualized system was built, and lessons learned along the way. Focus is not just on getting it to boot, but how to manage it once its there (think upgrades, backups, security, etc.)
