I posted this to the Xen Mailing Lists too but figured i should post 
here as well.

We are experiencing a odd issue after we built grub2 support.  The image 
we built works fine on some hosts and then just hangs on others.

I built grub2 as follows...
-------------
git clone http://git.savannah.gnu.org/cgit/grub.git
cd  grub
wget http://prgmr.com/~srn/grub2/xen-linux16.patch
patch -p1 < xen-linux16.patch
./autogen.sh
./configure --target=x86_64 --with-platform=xen --prefix=/opt/grub2
make
make install
export PATH=/opt/grub2/bin:/opt/grub2/sbin:$PATH

Next I built the image as follows...
---------------
cat > grub-bootstrap.cfg << EOF
normal (memdisk)/grub.cfg
EOF
cat > grub.cfg << EOF
for grubcfg in /boot/grub2/grub.cfg /boot/grub2/grub2.cfg 
/boot/grub/grub2.cfg /boot/grub/grub.cfg /grub2/grub2.cfg /grub/grub.cfg 
/etc/grub2.cfg /etc/grub.cfg ; do
    if search -s -f $grubcfg ; then
       echo "Reading (${root}$grubcfg"
       configfile $grubcfg
    fi
done
EOF
tar cf memdisk.tar grub.cfg
/opt/grub2/bin/grub-mkimage -O x86_64-xen -c grub-bootstrap.cfg -m 
memdisk.tar -o grub2-x86_64 /opt/grub2/lib/grub/x86_64-xen/*.mod

This works fine on some of our hosts, but then just seams to hang on 
others.  When starting the guest i see the following...

[root@devhostxxx ~]# xm create -c /home/username/vs.config
Using config file "/home/username/vs.config".
Started domain username (id=34)
                                  [root@devhostxxx ~]#

Then it just hangs from their.

These hosts are CentOS 6 using the CentOS-Xen RPMS. Hosts are running 
Xen version 4.4.1-8el6 and still using xend with xm commands


Any idea what may be going on here? Or how i should go about debugging 
this issue?

Are you able to add echo's along the way and look at xen console?
