Xen is a hypervisor (virtual machine engine) and it is the powerful open source industry standard for virtualization, offers a powerful, efficient, and secure feature set for virtualization of x86, x86_64, IA64, PowerPC, and other CPU architectures. It supports a wide range of guest operating systems including Windows, Linux, Solaris, and various versions of the BSD operating systems. All the major Linux distributions such as Red Hat, Oracle Linux, CentOS, Debian, Ubuntu, SuSe, and Gentoo provides packages for using Xen virtualization.
This GeekyFacts tutorial provides you step-by-step instructions on how to install & startup Xen. The commands mentioned in this document are for CentOS-5. So this document could very well apply for Fedora, Redhat Enterprise Linux & Oracle Enterprise Linux. For other Linux OS - it sould work with minimal changes.
In Xen, the host operating system is called dom0 (Domain 0) and the virtual guests are called as domU (Domain-U). |
