===== What So what is a container (Virtual Environment, Virtual Private Server, VPS, VE)Virtuozzo? =====:See [[Container]]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 are highlights of is OpenVZ technologyand how it compares to Virtuozzo? =====In short, OpenVZ is the only highly scalable virtualization technology with near-zero overheada free and opensource portion of Virtuozzo. It includes core of Virtuozzo functionality, strong isolation like kernel and rapid customer provisioning that's ready command line management tools for production use right nowcreating and managing containers. Deployment of Virtuozzo includes everything that OpenVZ improves efficiencydoes, flexibility plus additional features and quality of service in services available with the enterprise environmentcommercial version only.
===== Who needs How does Virtuozzo 7/OpenVZ? How it can be used? pair compares to its predecessor (Virtuozzo versions 4.x and 6/OpenVZ) =====:See [[Use cases]]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.
===== What applications can run inside an How OpenVZ containerusers will benefit from it? =====OpenVZ components will be undergoing 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.
===== How is Why I need Virtuozzo/OpenVZ different from other technologieswhen LXC exist? =====:See our [[Introduction to virtualizationcomparison]]of different virtualization solutions.
===== How is When OpenVZ secured & updatedwill be in upstream kernel? =====Our kernel developers [http:See [[Security]//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 Linux Containers (LXC) kernel, with features such as PID and network namespaces, memory controller, checkpoint-restore and much more.
===== I want to show my appreciation to OpenVZ technology scales as well as standard Linux kernel — up to thousands of CPUs and terabytes of RAM. Besides, a single container could be scaled up from taking a little fraction of available resources up put some logo to all resources available dynamically — you do not even have to restart the containermy site. For example, containers can natively use up Where to all available CPUs which is different from hypervisor technology which requires special tricks like co-scheduling and even the best hypervisors are inefficient with more then 4-8 vCPUsget it? =====:See [[Artwork]].
===== How does OpenVZ improve efficiency What kind of servicesdocumentation is available? =====
===== Who needs OpenVZ? How does OpenVZ improve flexibility of servicesit can be used? =====:See [[Use cases]].
===== What are performance expectations? ===== Peak performance is achieved when only one container has active tasks. In this case, it could use 100% of available resources: all CPUs, all physical memory, all disk and network bandwidth. OpenVZ is not limiting you to a single-CPU virtual machine. ===== I want to show my appreciation How to install OpenVZ and put some logo to my site. Where to get it? =====:See [[Artwork]].
===== What hardware is supported by OpenVZ kernel? =====
:See [https://hardware.redhat.com/ RHEL Hardware Compatibility List].
===== How existing OpenVZ users can upgrade to the [[Virtuozzo|new version]]? =====
While there is no in-place upgrade, we prepared [[Upgrade_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).
