Under my domU i have installed kernel-xen (since it is needed ) , and edited my grub menu to use the installed kernel. [snip]

I think you're missing the xenblk driver. Try editing /etc/modprobe.conf to look like this:

   alias eth0 xennet
   alias scsi_hostadapter xenblk

and then

   mkinitrd -f /boot/initrd-2.6.18-92.1.17.el5xen.img 2.6.18-92.1.17.el5xen
