Provide support and compatibility for virtualised environments

    • 18
    • We collect Confluence feedback from various sources, and we evaluate what we've collected when planning our product roadmap. To understand how this piece of feedback will be reviewed, see our Implementation of New Features Policy.

      The Confluence install guide at http://confluence.atlassian.com/display/DOC/Confluence+Installation+Guide currently says "Virtual Environments such as VMware are not recommended and thus not supported for clustered Confluence."

      This should be clarified, probably on a new page:

      • Explain which configurations, if any, are supported under VMWare or similar virtualisation. Are the Standalone and EAR/WAR under supported application servers considered supported if virtualised?
      • Make recommendations on which use cases/loads have acceptable performance when using a virtualised application server
      • Advise if testing shows that database cannot be virtualised due to performance impact
      • Add reasons why clustering is unsupported/incompatible
      • Link to any known bugs

            I have a problem - CPU sometimes spikes to 100%. I've read that the cause may be Virtual environment. I use VMWare and Confluence 3.0.2. Could anybody tell me what can I do. I didn't find anything in documentation.

            This really is great news! Is the support for virtualized Confluence limited to VMWare? Or do you also bless other virtualization platforms such as Citrix XenServer? What about opensource alternatives such as KVM virtualization on RHEL5 or Centos5 ? Sorry, had to ask.

            Well done guys! It sounds like the recommendation is still from large instances - stick to dedicated, but still good to be supported for our existing virtual instances!

            We've now published our official 'Confluence running on VMWare' results in the Confluence Documentation.

            We've also updated our note about our support for virtualisation (i.e. VMWare).

            I read the comment as Atlassian will support VMWare ESX environment ... but only once they complete their testing.

            It could also be interpreted as "go forth and try it out, but be patient with us if you experience issues as our knowledge base around virtualised environments is practically empty".

            The warning against using VMs is still on http://confluence.atlassian.com/display/DOC/System+Requirements

            Did I read Audra Eng's comment correctly? Atlassian now supports VMware ESX environments? This was a bone of contention for my team and would end the debate if this is correct. We are planning to migrate off of a physical box to a VMware ESX environment next month. Preliminary findings on a DEV system are good. Some sluggishness noticed but I am confident we can tune it (the performance was not so far off the mark ast to make us abondon the idea all together).

            I want to support the common opinion ...
            We are evaluation confluence, one critical requirement from IT side is the option to virtualize this application.

            Planned:

            • ESX3i with RHEL + SQL 2k5 DB Cluster
            • probable with an (exitsting) apache reverse proxy in front
            • finaly with 4000 named users
            • scoped as an corporate intranet

            strace on linux of frozen Confluence (restore operation in progress).

            Running on Oracle VM Server 2.1.5 (Xen 3.1.4). Guest OS is CentOS 5.3 x86_64

            I must note that I am seeing the futex/clock_gettime issue on Xen virtualization, both full (Hypervisor) virtualization and paravirtualization. I would be very interested in including this virtualization solution in the list.
