    Can you raise this question on centos-virt@centos.org? Also, can you provide more information about what and how you are installing?

    Hi,


    I installed xen 4.2.3 on centos 6.4 64bit , and created a new VM from the same iso by using the virt-manager.
    The installation took about 3 hours. The startup of the VM stay ay the progress bar, and the cpu is 100% .
    Is there any configruation to modify?
    Hardware: Intel E5800 , 320G, 6G

    The configuration is in the attachment.

    The detailed operation steps:

    1. Install centos on a machine ( Intel E5800, 320G, 6G), use the default partition setting, and install the virtualization components.
    2. Download xen packages from http://centos.arcticnetwork.ca/6.4/xen4/x86_64/Packages
    kernel-3.4.61-9.el6.centos.alt.x86_64.rpm
    kernel-devel-3.4.61-9.el6.centos.alt.x86_64.rpm
    kernel-doc-3.4.61-9.el6.centos.alt.noarch.rpm
    kernel-firmware-3.4.61-9.el6.centos.alt.noarch.rpm
    kernel-headers-3.4.61-9.el6.centos.alt.x86_64.rpm
    xen-4.2.3-23.el6.centos.alt.x86_64.rpm
    xen-devel-4.2.3-23.el6.centos.alt.x86_64.rpm
    xen-doc-4.2.3-23.el6.centos.alt.x86_64.rpm
    xen-hypervisor-4.2.3-23.el6.centos.alt.x86_64.rpm
    xen-libs-4.2.3-23.el6.centos.alt.x86_64.rpm
    xen-licenses-4.2.3-23.el6.centos.alt.x86_64.rpm
    xen-runtime-4.2.3-23.el6.centos.alt.x86_64.rpm

    3. Install kernel* first, and then install xen*,

    4. Modify grub.conf, add configuration:

    title Xen (3.4.61-9.el6.centos.alt.x86_64)
    root (hd0,0)
    kernel /xen.gz dom0_mem=5120M loglvl=all guest_loglvl=all
    module /vmlinuz-3.4.61-9.el6.centos.alt.x86_64 ro root=/dev/mapper/vg_eniac-lv_root rd_NO_LUKS LANG=en_US.UTF-8 rd_LVM_LV=vg_eniac/lv_swap rd_NO_MD rd_LVM_LV=vg_eniac/lv_root SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet crashkernel=auto
    module /initramfs-3.4.61-9.el6.centos.alt.x86_64.img

    5. Restart, select the Xen boot option.

    6. Start the virt-manager, install a VM. You can see the configuration in the folder vmconfig.

    Thanks.
