XEN with kernel 3.10.20 does not start (CentOS 6.4)

    I'm installing the latest version of XEN to CentOS 6.4 machine.
    XEN version: 4.2.3-25.el6.centos.alt
    kernel: 3.10.20-11.el6.centos.alt

    When I reboot, many messages appears on the screen, indication the loading of XEN and then.. just a black screen. This latest version of XEN and kernel was released on 25th of November, so it's very new. Several days ago I successfully installed XEN on another machine, but that was XEN 4.2.3-23 and kernel 3.4.68-9. And now, after they released a new version, it stopped working..

    Also if I try to load a new kernel without XEN - it works perfectly.

    Please help me determine what's wrong with the new XEN kernel. Thanks.

    I still have no idea why doesn't it work, but I've found a workaround. If anyone is experiencing the same issue - try to install the earlier version of kernel.
    In CentOS this is done by:
    yum install kernel-3.4.68-9.el6.centos.alt.x86_64

    Then edit /etc/grub.conf and make sure this kernel will be loaded and used by XEN instead of 3.10.20.

    I have the same probleme as above.

    After i updated the system CentOS 6.4 (yum -y update)
    Centos 6.5 was installed then i used

    yum install centos-release-xen
    yum install xen

    my grub.conf shows 3.10.20-11.el6.centos.alt
    but when I restart the system is not loading any more ??

    It says: FATAL: Module scsi_wait_scan not found


    Maybe the CPU is not compatible? Its a 2x Intel L5630

    Okay is this strange!
    I did a fresh installation of CentOS 6.5 in a Virtual Box

    yum -y update
    yum install centos-release-xen
    yum install xen

    Restarting the VM and the kernel 3.10. is loaded :-(

    Same problem

    Hello there,
    I installed CentOS 6.5 minimal on VM VirtualBox 4.3.8
    This works fine.
    After this I enabled CentOS-Extras repo and installed Xen
    yum install http://fedora.cu.be/epel/6/x86_64/epel-release-6-8.noarch.rpm
    yum install centos-release-xen
    yum install xen
    Now the virtual machine constantly reboots :(
    I add 2 screenshots that I could take before the reboot
