OpenVPS is a set of software built on top of the Linux VServer aimed specifically at Web Hosting. It is not another set of kernel patches, but a set of scripts to create virtual servers, collect resource utilization information, and provide an interface to the customer as well as the administrator.
PyreRing is a test runner that executes scripts intended to act as individual test cases. By removing the administrative burden that often surrounds testing, the test author can focus on writing meaningful, direct, and useful test cases. As long as you wrap your test cases with a Unix shell or scripted language wrapper, it will be executed. It allows you to set a timeout value, send reports to email addresses, automatically organize your test cases with filesystem directories or suite files that you define, create automatic suites based on a predefined block in your test scripts, and capture standard out and standard error into a comprehensive log.
