{{Virtuozzo}}
== General ==
===== How So what is OpenVZ different from other technologiesVirtuozzo? =====:See [[Introduction Virtuozzo is a Linux based virtualization platform, combining container and hypervisor virtualization, into a single product. While primarily built for service providers to virtualization]]run cloud services and applications, it is used by variety of businesses, including MSP, SMB and Enterprises.
===== How What is OpenVZ secured & updatedand how it compares to Virtuozzo? =====:See [[Security]]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 scalable is 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 technology scales perfectly users will benefit from it? =====OpenVZ components will be undergoing the same testing procedures as standart Linux kernel does - up to thousands of CPUs and TBs of RAMthe commercial product. BesidesAlso, a single container could be scaled up from taking a little fraction of some new features previously available resources up to all resources on Virtuozzo only (notably hypervisor) will become available dynamically - you do not even have to restart on the container. For example, containers can natively use up to all available CPUs which is different from hypervisor technology which requires special tricks like co-scheduling and even best hypervisors are inefficient with more then 4-8 vCPUsproduct built for OpenVZ community users.
===== How does OpenVZ improve efficiency of servicesWhat 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].
===== How does When OpenVZ improve flexibility of serviceswill be in upstream kernel? =====Our kernel developers [http://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 and put some logo to my site. Where to get it? =====
:See [[Artwork]].
===== Are there any control panels What kind of documentation is available for OpenVZ? =====:See [[Control_panels]].
===== What hardware is supported by Who needs OpenVZ kernel? How it can be used? =====:See [http://www.parallels.com/en/products/virtuozzo/hcl/ Virtuozzo HCL[Use cases]].
===== Why there are different kernel flavours available and what do they meanHow scalable is OpenVZ? =====:See [[Different kernel flavors (UP, SMP, ENTERPRISE, ENTNOSPLIT)]].
==Installation and upgrade === What does 021stab018 in OpenVZ kernel version mean? =====:See [[Kernel versioning]].
===== How can I check package signaturesto install OpenVZ? =====:See [[Package signatures]].
== Quick reference card for === How existing OpenVZ users can upgrade to the [[Virtuozzo|new version]]? ====={{PDFlinkWhile there is no in-place upgrade, we prepared [[Upgrade_script_from_OpenVZ_to_Virtuozzo_7|[http://pronicsupgrade script]] for OpenVZ users to move their containers to the new platform.fi/~eero/mirrors/openvz-reference-cardThe script allows to transfer containers from old to new OpenVZ version (or from OpenVZ to Virtuozzo).pdf openvz-reference-card.pdf]}} BROKEN LINK
