Container-based virtualization

OpenVZ is 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. For more information about the technology and how it differs from the others like Xen, VMware etc.

OpenVZ software consists of an optional custom Linux kernel and command-line tools (mainly vzctl). Our kernel developers work hard to merge containers functionality into the upstream Linux kernel, making OpenVZ team the biggest contributor to Linux Containers (LXC) kernel, with features such as PID and network namespaces, memory controller, checkpoint-restore and much more. OpenVZ tools (vzctl) is a solid alternative to LXC tools. While OpenVZ can be used with recent upstream kernel, we recommend using OpenVZ kernel for security, stability and features.

Kernel-based Virtual Machine (KVM)

Open source hypervisor KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It is a kernel module added to mainline Linux.
With KVM you can run multiple virtual machines by running unmodified Linux or Windows images. It enables users to be agile by providing robust flexibility and scalability that fit their specific demands. Proxmox Virtual Environment uses KVM virtualization since the beginning at 2008, since 0.9beta2.

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM also requires a modified QEMU although work is underway to get the required changes upstream.

Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
The kernel component of KVM is included in mainline Linux, as of 2.6.20. KVM is open source software.
