Re: Fwd: Re: [Xen-users] New to Xen



Simon... thanks for the info. Sounds like things are a little easier since my last round of Xen3/Lenny installs. Have the various nits re. pinning CPUs (to avoid weird crashes) and having to set up clock jiffies gone away - or is there a new round of nits that have to be picked?

Andrew... was that really called for?

        Personally, I do most of my work on Debian, and my production
        servers are still running Lenny and Xen 3 - so my experience
        is dated (and about to get refreshed):

        - the basic install is easy: simply an apt-get of the current
        package

        - there's a bit of trickiness in getting all the various
        configuration stuff right - in lots of places (from kernel
        parameters in Grub and on - and I expect this has changed
        again, what with grub changes going from Lenny to Squeeze) -
        there are things to worry about like memory ballooning,
        pinning VCPUs, time sources, etc. -- make sure to read through

    All my systems are Debian (mostly Squeeze now) apart from one.
    Xen is fairly easy to set up, and I think if you stick to simple
    stuff then it's little more than "apt-get install
    xen-hypervisor-<something> xen-tools-<something>". "apt-cache
    search xen-hypervisor" will show you the package versions available.

    The main niggle (as already hinted at) is that Grub2 defaults to
    putting Xen boot options after native kernels. The easy fix for
    that is to change the name of the files in (IIRC) /etc/grub so
    that the Xen config file comes before the native kernels (Linux)
    config file.

    Initially, avoid trying to get PyGrub working. Just copy the DomU
    kernel and initrd to Dom0 and boot from those. PyGrub does mostly
    work, but it can be a bit fiddly getting the right version of Grub
    that will run in a DomU - the version in Stable (Squeeze) bombs
    out as it can't understand the disk setup.

        Gee Sigmund, ... Bravo !

        I am sure Basil Fawlty would have a field day with this line.

        You should get away from that hot server air and AMD
        processors you're running.
        What I heard they are made in Dresden Sachsen DE.
        Those chips tend to de-gass (an old habit of chips made there)
        a lot compared to Intel and it can easily place a normal
        person in DomU if you use the server air to blow dry your hair
        every morning before you go look in the mirror to figure out
        who you are.

        Just good advice.


    Sorry, but you really are not doing yourself any favours. You
    posted an (IMO) suboptimally worded request which resulted in some
    flames. If you continue with insults then you merely confirm to
    some people that you aren't to be taken seriously and perhaps
    aren't worthy of help - there are people who require help and who
    are able to put that sort of thing to one side, if someone has to
    choose who to give their time to, then the polite and rational
    person is likely to win.
