Xen-4.2 on CentOS 6.4 host can't boot


Hello,

I've followed this tutorial to install Xen4CentOS on CentOS 6.4.

When I boot the server with Xen, Grub gives this error:

Code:
invalid magic number: 9090
Error 13: Invalid or unsupported executable format
The server supports EFI. To solve the problem, I've tried to copy "/boot/efi/EFI/redhat/grub.conf" to "/boot/grub/grub.conf" and run "grub-install sda", but it didn't work.

My grub.conf is as below:
Code:
default=0
timeout=5
splashimage=(hd0,1)/grub/splash.xpm.gz
hiddenmenu
title CentOS (3.4.59-8.el6.centos.alt.x86_64)
        root (hd0,1)
        kernel /xen.gz dom0_mem=1024M,max:1024M loglvl=all guest_loglvl=all
        module /vmlinuz-3.4.59-8.el6.centos.alt.x86_64 ro root=/dev/mapper/vg_server-lv_root rd_NO_LUKS  KEYBOARDTYPE=pc KEYTABLE=us LANG=en_US.UTF-8 rd_LVM_LV=vg_server/lv_root rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=vg_server/lv_swap rd_NO_DM rhgb quiet
        module /initramfs-3.4.59-8.el6.centos.alt.x86_64.img
title CentOS (2.6.32-358.18.1.el6.x86_64)
        root (hd0,1)
        kernel /vmlinuz-2.6.32-358.18.1.el6.x86_64 ro root=/dev/mapper/vg_server-lv_root rd_NO_LUKS  KEYBOARDTYPE=pc KEYTABLE=us LANG=en_US.UTF-8 rd_LVM_LV=vg_server/lv_root rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto rd_LVM_LV=vg_server/lv_swap rd_NO_DM rhgb quiet
        initrd /initramfs-2.6.32-358.18.1.el6.x86_64.img
I will be happy if you help me to solve this issue.

Thanks.

Having the same issue

Followed the same tutorial, and I am having the same issue. Wondering if it might be related to Johnny Hughes' updates?

Hopefully it's nothing too complicated...
