Xen users - Nov 2014 - Dom0's Booting problem on RedHat enterprise linux 7

Hi,
    I used to be working under Debian but recently I've moved on to Redhat.
I compiled and installed Xen 4.4.1 on redhat linux 7 x64 with linux 3.1-.59
kernel. after that I add an entry in /boot/grub2/grub.cfg. I copied a default
one and made some change, in which I wrote:

menuentry 'Xen 4.4.1, Red Hat Enterprise Linux Server (3.10.59) 7.0
(Maipo)' --class red --class gnu-linux --class gnu --class os --unrestricted
$menuentry_id_option
'gnulinux-3.10.0-123.el7.x86_64-advanced-4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5'
{
load_video
set gfxpayload=keep
insmod gzio
insmod part_msdos
insmod ext2
set root='hd0,msdos6'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos6
--hint-efi=hd1,msdos6 --hint-baremetal=ahci1,msdos6 --hint='hd0,msdos6'
4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5
else
search --no-floppy --fs-uuid --set=root 4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5
fi
echo 'Loading Xen 4.4.1'
multiboot /boot/xen-4.4.1.gz placeholder dom0_mem=4096M dom0_max_vcpus=8
loglvl=all iommu=1
echo 'Loading Linux 3.10.59'
module /boot/vmlinuz-3.10.59 root=UUID=4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5 ro
nomodeset pci_pt_e820_access=on crashkernel=auto vconsole.font=latarcyrheb-sun16
vconsole.keymap=us rhgb quiet LANG=en_US.UTF-8
echo 'Loading initial ramdisk ...'
module /boot/initramfs-3.10.59.img
}

I added some options like iommu=1. But I was and am pretty sure they're not
the problem.
I noticed that the default grub.cfg used linux16 and initrd16 instead of linux
and initrd (in Debian). Like this:

menuentry 'Red Hat Enterprise Linux Server (3.10.0-123.9.3.el7.x86_64) 7.0
(Maipo)' --class red --class gnu-linux --class gnu --class os --unrestricted
$menuentry_id_option
'gnulinux-3.10.0-123.el7.x86_64-advanced-4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5'
{
load_video
set gfxpayload=keep
insmod gzio
insmod part_msdos
insmod ext2
set root='hd0,msdos6'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos6
--hint-efi=hd1,msdos6 --hint-baremetal=ahci1,msdos6 --hint='hd0,msdos6'
4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5
else
search --no-floppy --fs-uuid --set=root 4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5
fi
linux16 /boot/vmlinuz-3.10.0-123.9.3.el7.x86_64
root=UUID=4a6ecbd4-e01b-4030-ab09-a43d5b6f63b5 ro nomodeset crashkernel=auto
vconsole.font=latarcyrheb-sun16 vconsole.keymap=us rhgb quiet LANG=en_US.UTF-8
initrd16 /boot/initramfs-3.10.0-123.9.3.el7.x86_64.img
}

 So dose that lead to the problem? And what a correct Xen entry should be? 



Best regards,
Kenneth
