Xen Kvm Openvz. Virtualization is the act of making virtual version of a physical resource so that can be run or stored for one or more several virtual version at once. Kvm is true virtualization, each guest is independent of the host.
However because it doesn't have the overhead of a true hypervisor it is very fast. Kvm has no restrictions in terms of functionality. Openvz allows a physical server to run multiple isolated operating system instances, called containers, virtual private servers (vpss), or virtual environments (ves).
Xen is an open source hypervisor, included in linux kernel.
About me migrate openvz container to kvm/xen vm 27 january 2013 on sysadmin, centos, kvm, openvz. Linux kvm, openvz, and xen devops by timothy hudson tags : Openvz is a container virtualization which relies on the host node kernel.
First of all, the most basic difference between openvz and kvm is that openvz can only host linux operating systems, while kvm is more flexible and can host linux, windows.
All virtual servers have to get along with the kernel version the host runs on. Xen is a hypervisor that enables simultaneous creation, execution, and management of multiple virtual machines on one physical computer. All openvz containers share the same architecture and kernel version.
Xen is offered in 2 flavors, which can basically run simultaneously on the same physical host, xen hvm (full hardware virtualisation) and pv (paravirtualisation).
As a point of contrast, with both virtuozzp and openvz you can only use the version/distro of the operating system (linux, windows, etc.) that is used on your host server, because all sites/accounts on the server use the same operating system. Kvm is true virtualization, each guest is independent of the host. Openvz compared to other virtualization technologies.
After all, a vps is a fantastic way to run an operating system without a physical computer of.
Xen can do full virtualization on systems that support virtualization extensions, but can also work as a hypervisor on machines that don’t have the virtualization extensions.

Kvm has no restrictions in terms of functionality. This allows the server to multi task. The only downside is that a xen or kvm based server will perform slightly slower than an equivalent virtuozzo setup.
