13. Open Source Linux Virtualization Software OpenVZ is an operating system-level virtualization technology based on the Linux kernel and operating system.
14. Open Source Linux Virtualization Software Xen is a virtual machine monitor for 32 / 64 bit Intel / AMD (IA 64) and PowerPC 970 architectures. It allows several guest operating systems to be executed on the same computer hardware concurrently. XEN is included with most popular Linux distributions such as Debian, Ubuntu, CentOS, RHEL, Fedora and many others.
15. Open Source Linux Virtualization Software Kernel-based Virtual Machine (KVM) is a Linux kernel virtualization infrastructure. KVM currently supports Native virtualization using Intel VT or AMD-V. A wide variety of guest operating systems work with KVM, including many flavors of Linux, BSD, Solaris, and Windows etc. KVM is included with Debian, OpenSuse and other Linux distributions.
16. Open Source Linux Virtualization Software Linux-VServer is a virtual private server implementation done by adding operating system-level virtualization capabilities to the Linux kernel
The virtualization system presents to the user a logical space for data storage and itself handles the process of mapping it to the actual physical location.
