; Who needs ===== So what is Virtuozzo? =====Virtuozzo is a Linux based virtualization platform, combining container and hypervisor virtualization, into a single product. While primarily built for service providers to run cloud services and applications, it is used by variety of businesses, including MSP, SMB and Enterprises. ===== What is OpenVZand how it compares to Virtuozzo? =====OpenVZ is a free and opensource portion of Virtuozzo. It includes core of Virtuozzo functionality, like kernel and command line management tools for creating and managing containers. Virtuozzo includes everything that OpenVZ does, plus additional features and services available with the commercial version only.  ===== How does Virtuozzo 7/OpenVZ pair compares to its predecessor (Virtuozzo versions 4.x and 6/OpenVZ) =====Previously, OpenVZ and Virtuozzo were built out of the same code base with some unique patches applied. That warranted the user interfaces to be similar but not identical. With Virtuozzo 7, the compatibility will be on the binary level - effectively the open source components will be the same between OpenVZ and Virtuozzo. ===== How OpenVZ users will benefit from it can ? =====OpenVZ components will be usedundergoing the same testing procedures as the commercial product. Also, some new features previously available on Virtuozzo only (notably hypervisor) will become available on the product built for OpenVZ community users. ===== What support options are available for Virtuozzo 7?=====For the moment, only preview (beta) versions of Virtuozzo 7 are available. They are intended for development and testing only, not for production. Virtuozzo 7 is not yet commercially supported. For supported commercial version, please refer to [http: //www.odin.com/products/virtuozzo/ Virtuozzo 6]. ===== Why I need Virtuozzo/OpenVZ when LXC exist? =====See our [[Use casescomparison]]of different virtualization solutions.

; How is ===== When OpenVZ different from other technologieswill be in upstream kernel?=====Our kernel developers [http: See [[Introduction //openvz.org/File:Kernel_patches_stats.png work hard] to merge containers functionality into the upstream Linux kernel, making OpenVZ team the biggest contributor to virtualization]]Linux Containers (LXC) kernel, with features such as PID and network namespaces, memory controller, checkpoint-restore and much more.

; Is it possible to run x86 VPS on a x86_64 arch?There are two versions of OpenVZ available: Sure :) We actually did some work on that to enable migration of x86 VE from x86 to x86_64 and back, and to enable using 32-bit iptables in 32bit VE on an x86_64 system.

== Networking ==; How do I set up VPN for a VE?* [[Roadmap|stable version]]: OpenVZ legacy (based on RHEL5 and RHEL6 kernels).* [[Roadmap|development version]]: See [[VPN via the TUN/TAP deviceVirtuozzo]]Linux distribution based on RHEL7 kernel.

; I see a lot of processes in D state. What does that mean===== How existing OpenVZ users can upgrade to the [[Virtuozzo|new version]]?=====: See While there is no in-place upgrade, we prepared [[Processes in D stateUpgrade_script_from_OpenVZ_to_Virtuozzo_7|upgrade script]]for OpenVZ users to move their containers to the new platform. The script allows to transfer containers from old to new OpenVZ version (or from OpenVZ to Virtuozzo).
