Arch PV guest in Xen won't boot

Hi,

I have Xen installed and running several (win 7) HVMs.  I've setup an Arch PV guest but I am having a problem booting it.  After each failed attempt to fix this issue I try to view the /var/log/xen/bootloader.XX.log file but all of these files are zero bytes.  So, I'm having some trouble troubleshooting this.  I followed the instructions from https://wiki.archlinux.org/index.php/xen on setting up an Arch PV and do not think I missed anything.

This is the error message I get:

[root@earth arch1]# xl create -c /vm/arch1/arch1.conf
Parsing config from /vm/arch1/arch1.conf
libxl: error: libxl_bootloader.c:628:bootloader_finished: bootloader failed - consult logfile /var/log/xen/bootloader.85.log
libxl: error: libxl_exec.c:129:libxl_report_child_exitstatus: bootloader [-1] died due to fatal signal Killed
libxl: error: libxl_create.c:1022:domcreate_rebuild_done: cannot (re-)build domain: -3

This is the vm conf that I use to boot the arch install iso after loop mounting it.

name = "arch1"
kernel = "/mnt/arch/boot/x86_64/vmlinuz"
ramdisk = "/mnt/arch/boot/x86_64/archiso.img"
extra = "archisobasedir=arch archisolabel=ARCH_201410"
memory = 1024
vif =  [ 'mac=00:16:3E:42:01:3D,bridge=xenbr0,model=e1000' ]
disk = [ '/vm/arch1/arch1.img,,hda,w', '/vm/img/ARCH_201410.iso,,hdb,cdrom']

This is my vm conf used to boot the VM after installing arch and umount-ing the loop mounted iso:

name = "arch1"
bootloader = "pygrub"
memory = 1024
vif =  [ 'mac=00:16:3E:42:01:3D,bridge=xenbr0,model=e1000' ]
disk = [ '/vm/arch1/arch1.img,,hda,w']

And this is an abbreviated version of how I install arch on the VM.  During the install I don't think I've missed anything from the wiki.
My understanding is that pygrub will take care of booting as long as  /boot/grub/grub.conf is exists and is setup correctly which I believe I have done.
I copied the sample grub.conf from "Xen - ArchWiki" and used the UUID for "/" found in /etc/fstab (its the same I get from blkid)

The wiki mentions that without certain modules in  /etc/mkinitcpio.conf the VM will not boot.  But I've added them as shown below. 

So I'm not sure why I'm getting the above error.

gdisk /dev/xvda

lvcreate -L 1G -n home arch

mkfs.ext4 -F /dev/mapper/arch-root
mkfs.ext4 -F /dev/mapper/arch-home

mount /dev/mapper/arch-root /mnt

mkdir /mnt/home
mount /dev/mapper/arch-home /mnt/home 

pacstrap -i /mnt base base-devel

genfstab -U -p /mnt >> /mnt/etc/fstab

arch-chroot /mnt /bin/bash

#setup /etc/locale.gen & /etc/locale.conf
#setup host name
#setup network

sed -i 's/MODULES=\"\"/MODULES=\"xen-blkfront\ xen-fbfront\ xen-netfront\ xen-kbdfront\"/g' /etc/mkinitcpio.conf 
mkinitcpio -p linux
 
mkdir /boot/grub
cd /boot/grub
cat /etc/fstab
#create /boot/grub/grub.conf based on the sample from "Xen - ArchWiki" with the UUID for "/" found in /etc/fstab (its the same I get from blkid)

After doing the above install I poweroff and umount the loop mounted iso. I then get the above error message when running xl create.  Unfortunately the bootloader logs are empty.
