Knoppix-OpenVZ – a live CD based on Knoppix 5.1.1 which features the OpenVZ technology.
OpenVZ is a container-based virtualization for Linux. OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files. OpenVZ is free open source software, available under GNU GPL.
The Live CD contains the OpenVZ patched kernel 2.6.18-028stab027, the utility vzctl 3.0.16 and the program vzquota 3.0.9. Furthermore, minimal templates (file system archives that can be unpacked to set up virtual machines) have been added for Debian 3.1, CentOS 4, and Fedora Core 5. To make room for it, the developers renounced Knoppix on OpenOffice, GIMP and Frozen Bubble.
The booted system runs completely in the RAM of the computer. The number of virtual machines (VEs) that can be set up and started depends on the available RAM. With 1 GB of main memory, about five VEs should start.
OpenVZ is the free base of the commercial solution »Virtuozzo« from SWsoft. It virtualizes the operating system, but not the hardware. This means a kernel (Linux with OpenVZ patch) is running, and this provides a number of virtual environments. Each of these VEs feels very much like a separate computer
The OpenVZ development team has created a live CD that can be used to test the OpenVZ technology without installing it on the computer.
