Reading the log files....
I discovered that the hotplug script is looking in a folder that does not
exist?!
" /var/run/xen-hotplug/block/owner: No such file or directory "
So
I manually made a directory under /dev/run/xen-hotplug
again I get errors:(In the hotplug log file):
/etc/xen/scripts/locking.sh: line 97: /var/run/xen-hotplug/block/owner: No
such file or directory
Nothing to flush.
So again I went ahead and made those folders manually.

Again errors:

xenstore-read: couldn't read path backend/vbd/4/769/node
xenstore-read: couldn't read path backend/vbd/4/770/node

Now I am stuck! 
I am pretty sure that there is a problem with reading a volume bcs it
returns an error saying sda1 is invalid (and I am using it)!? it says
/dev/sda1 is not there .
All I get is an initramfs prompt. not a functioning FS!
