      all Xen3 installed domU's should run without any issues on Xen4.

    From my experience this is true if you keep using xm toolstack.<br>
    When I switched to Xen4.1.2 I had to modify some configuration files
    (mostly because of management software that was used to put
    "proprietary values in thoose files) that xl could not process.<br>
    Further more I also noticed really worst performances when starting
    a domain with xl than with xm.<br>
    I just kept using xm and didn't really dig into the problem, so am
    not sure this is general or if you would face it too... But this is
    what happened to me.<br>
    <br>
    regards.<br>

        Currently I am running xen 3.4.2 on one of my Centos servers , I
        want
        <br>
        to upgrade to latest version of xen but I dont know if I should
        <br>
        upgrade to latest branch of xen 3 or xen 4 ? is xen 4 backward
        <br>
        compatible with xen 3 VMs ? does it provide any performance
        benefit
        <br>
        compared to xen 3 ?
        <br>
        What is your recommendation ?
        <br>
        Regards
