If you want to set up a mirror of OpenVZ downloads, here's how.

== Requirements == 


{{Warning|Please do NOT set up public OpenVZ mirror if:
* you don't have enough resources (disk space, bandwidth, admin staff);
* you are not committed to maintaining it for at least years;
* you do not have automatic monitoring in place and staff to fix it quickly.}}


* The mirrored content should be available through HTTP and FTP; both are optional but of course at least one should be there. In addition, you might provide rsync access — this is highly optional.


* Your http/ftp servers should return correct status for non-existent files (HTTP 404, FTP 550).


* Your mirror should be updated on a regular basis; 1 hour period is recommended.


* You should have some monitoring in place to check that your mirror is up to date and working properly and serving the files using all the protocols it supports


If you can not set up a system conforming to the above requirements — please don't attempt it.

== Setting up the mirroring process == 


To initially mirror the contents, run:


* United States: <pre>rsync -av --delete rsync://download.openvz.org/openvz-download /local/path</pre>
* Europe: <pre>rsync -av --delete rsync://eu.download.openvz.org/openvz-download /local/path</pre>


Next step is to add the cron job to run the same rsync command regularly. It is suggested to do that at least hourly.

== Setting up an access to your mirror == 


When you are ready to open up your mirror, set up HTTP/FTP access to it. Preferrably, the mirror should be available at <tt><nowiki>http://openvz.yoursite.com/</nowiki></tt> or <tt><nowiki>http://mirrors.yoursite.com/openvz/</nowiki></tt> (same with ftp).

== Announcing your mirror == 


Final step is to announce the mirror. There are two options:


* send a pull request to [https://src.openvz.org/projects/OVZ/repos/openvz-mirrors/browse openvz-mirrors] repository and add sergeyb@ as reviewer (preferred way)
* send an email to [mailto:mirrors@openvz.org mirrors@openvz.org]


Announce should contain at least the following information (see [https://src.openvz.org/projects/OVZ/repos/openvz-mirrors/commits/c85b848e76c35b216ef157cbc6d1eb823a596d7e example of announce]):


* '''Site:''' - website address. Example: hosteurope.de.
* Direct links to OpenVZ files on your mirror (http, ftp, rsync). Example:
** OVZ-https: download.openvz.org/
** OVZ-ftp: download.openvz.org/
** OVZ-rsync: download.openvz.org/openvz-download/
* '''Maintainer''' - email address of mirror admin (whom to contact in case of problems). It will better be some generic address (like mirroradmin@ or something), forwarded to at least a few people.
* '''Country''' (code of country from ISO 3166-1, see a list [http://www.staff.science.uu.nl/~penni101/mirmon/svn/trunk/countries.list here])
* '''Location''' - physical location of your mirror. Example: Sergiev Posad, Moscow region, Russia.
* '''Sponsor''' - name of your organization
* '''IPv6''' - IPv6 support for your mirror (yes, no).
* '''Comment''' - additional information, like bandwidth, update frequency etc. Example: 1GB connection, updated hourly.
* '''Master site''' - currently we have two master sites: [https://download.openvz.org download.openvz.org] (USA) and [https://eu.download.openvz.org eu.download.openvz.org] (Switzerland, Europe). Please setup mirroring from nearest OpenVZ master site and specify it in this field.


Example of information about new mirror:


Site: eu.download.openvz.org
Type: Master
OVZ-https: eu.download.openvz.org/
OVZ-ftp: eu.download.openvz.org/
OVZ-rsync: eu.download.openvz.org/openvz-download/
Maintainer: Sergey Bronnikov <sergeyb@openvz.org>
Country: ch
Location:
Sponsor: Virtuozzo
IPv6: yes
Comment: Master site
State: Enabled

== Some stats == 


OpenVZ download site is about 103 Gb now (as of Aug 2015), so your mirror will need at least the same space. It is growing at about 1.5 GB per month.


The traffic for download.openvz.org is about 3T to 15T per month; it should be much lower than that for your mirror.

{{Virtuozzo}}

<translate>
== General == 

===== 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 OpenVZ and 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? ===== 
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.

===== 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 [[comparison]] of different virtualization solutions.

===== When OpenVZ will 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]].

===== What kind of documentation is available? ===== 


:Aside from this wiki, which contains lots of information, you can check extensive [[Man|manual pages]] and [http://docs.openvz.org Virtuozzo documentation].

===== Who needs OpenVZ? How it can be used? ===== 
:See [[Use cases]].

===== How scalable is OpenVZ? ===== 


OpenVZ technology scales as well as standard Linux kernel — up to thousands of CPUs and terabytes of RAM. Read more about [[WP/Containers_density|OpenVZ containers density]] and [[performance]].

== Installation and upgrade == 

===== How to install OpenVZ? ===== 


There are two versions of OpenVZ available:


* [[Roadmap|stable version]]: OpenVZ legacy (based on RHEL5 and RHEL6 kernels).
* [[Roadmap|development version]]: [[Virtuozzo]] Linux distribution based on RHEL7 kernel.


See [[Quick installation]]

===== 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).
