Thread: Xen schedulers in openSUSE 11.2

  1. #1

    Question Xen schedulers in openSUSE 11.2

    We are into project of modifying scheduler for xen.
    Improvement over sedf / Credit.

    We are unable to find out the necessary documentation regarding schedulers in xen.
    Neither any settings in config files.

    Is the option of setting schedulers in xen ruled out in openSUSE 11.2?

    Plz help up in this regard.

    Thanking,
    Project Members.

    This thread was previous in the wrong sub forum area, so I have moved this to applications in the hope that the user gets better support in this new location.

    I have to say that I am a complete dummy when it comes to xen (I use vmware
    products). So what I can say is very limited, I looked into the pdf files
    shipped in the package xen-doc-pdf and there are some very short references
    to the scheduler. So I would be very surprised if it is ruled out.

    The only thing I found quickly is this article

    http://tiny.cc/1s1WZ

    which references a book.

    It notes the command

    # xm dmesg | grep scheduler

    to see which scheduler is used in your xen.

    Maybe there are not that many xen users here (?), I don't know.
    I found plenty of xen docs and books and forums in german (to my surprise),
    maybe you should post your question simply in an english xen forum if you
    get no answer here.

    We have found out the way to change the schedulers, vary the different parameters etc.

    we now want know, where exactly is the code for xen schedulers, to understand its implementation details.

    we could find some bits and pieces about credit.

    but not the complete code where scheduling is handled.

    Hmm I'd think that the full source should be in the xen source package. That should be available in the source repository it is OSS after all.

    It looks like it is integrated with openSUSE.
    we could not find any hint of where the code for scheduler is.
