XenServer 6.2 Is Now Fully Open Source

Posted by timothy on from the boundless-bounty dept.

First time accepted submitter Jagungal writes "Although the core Xen hypervisor has always been open source from the start, Citrix have now released the next version of their XenServer including all features and tools under an open source license. This includes also introducing a new XenServer.org community portal. The major change for users is that they now get all features from the licensed version for free but unless they pay for support, they have to do all security updates manually. Change logs for the new version 6.2 can be found here. It's been a few years since Citrix started giving it away, free as in beer.

    and it was the best choice we ever made.

    live migration is free (as in beer). and it runs its little heart out with no problems.

    2 years now, 30 TB of files, 40 GB of mysql data, about 30 VMs on 4 hosts. not one single problem.

    The only issue we've run into is getting fully paravirtualized FreeBSD. It is a rather involved process. But once you have one VM you just copy it like a template. And luckily ZFS On Linux is starting to be good enough so we don't have to really care about FreeBSD so much.

    Plain-vanilla Xen (not Xenserver) with DRBD (et al.) making instant failover is pretty awesome too.

    Fuck VMWare.

      The Zimbra Open Source Edition is probably a very good choice.
      - 99% of all companies don't need features then the open source edition.
      - it supports large mailboxes very well. ( some of our employees have 21gb mailboxes, it still runs smooth )
      - You can buy a plugin for encryption if you really need it.
      - Mail (IMAP), Calender (iCal) and adressbook (LDAP) sync is possible to almost any device.
      - You can always get the commercial version if you need the extras.

      I don't think you can remotely wipe your mail using an open source product but nowadays you might simply get any android of iphone device and use a wiping app. Maybe not as convenient but it works.

      Spamassasin can work very well ( it certainly does for us ) using external blocklists and distributed mail analysis services ( dcc, razor2 ) in addition to it's core filters. We added greylisting as well. Everything runs as part of the Amavis product. We don't use Bayesian filtering though. While good on paper we found it to be to unpredictable in real life. ( people reporting valid mailing lists as spam instead of unsubscribing, etc ) Instead we added around 15 additional custom spam filter lines over the years but that's it. Now all our spam is gone. We filter mail for over 1500 domains and our customers have never been happier.

    According to

    http://www.xenserver.org/about-xenserver-open-source/gplv2-license.html

    the licenses used include:

    AFL
    Artistic
    ASL 2.0
    BSD
    BSD-like
    LGPL (v2+, v2.1 , v2.1+, v3+, v2+ with linking exception, with linking exception)
    GPL (v2, v2+, v3, v3+, unspecified version, v2 with linking exception)
    OSL
    MIT (v1.1, unspecified version)
    OpenLDAP
    Zlib
    PSF

    That list also includes:

    Qlogic (link is to http://www.qlogic.com/supportx0/agreement.asp , but that's borked)
    Public Domain
    pubkey (artefact; refers to GPG keys for some reason)
    Proprietary
    Distributable
    Freeware

    I'm just a simple hyperchicken lawyer from Andromeda, but in my galaxy, proprietary licenses aren't 'open source' let alone Free software licenses. Same goes for freeware, public domain, etc.

    For the curious, the proprietary-licensed stuff includes software from Brocade Communications, Citrix Systems (!), Emulex, and QLogic.
