I am trying to run a CentOS DomU on Debian Dom0 .
I created a VM using QEMU and it boots fine.(Except network connectivity)

Now for Debian Dom0
I created the new_centOS.cfg
added following

bootloader = "/usr/lib/xen-3.2-1/bin/pygryb" (there was no softlink
from /usr/lib/xen-3.2-1/bin/pygryb to /usr/bin)
boot = "c"

full file uploaded here
http://pastebin.com/daeGSSpS

and then tried to boot
got an error

openworld:/etc/xen# xm create new_centOS.cfg
Using config file "./new_centOS.cfg".
Error: Bootloader isn't executable
about the above error on this link
http://wiki.debian.org/Xen#A.22Error.3ABootloaderisn.27texecutable.22
some information was but it did not helped.As what they were saying I
had already done.

Then checked this link
http://strugglers.net/~andy/blog/2008/01/20/red-hat-based-linux-under-xen-from-debian-etch/

I did
usr/lib/xen-3.0.3-1/bin/pygrub /dev/virtualization/centos5-disk xvda

I get a brub screen .
A snapshot for the pygrub booting can be seen here

But it fails to boot.

Giving following message.

Traceback (most recent call last):
File "./pygrub", line 657, in <module>
dir="/var/run/xend/boot")
File "/usr/lib/python2.5/tempfile.py", line 302, in mkstemp
return _mkstemp_inner(dir, prefix, suffix, flags)
File "/usr/lib/python2.5/tempfile.py", line 236, in _mkstemp_inner
fd = _os.open(file, flags, 0600)
OSError: [Errno 2] No such file or directory:
'/var/run/xend/boot/boot_kernel.je5fbt'

I searched this but it did not gave me a single search result
http://www.google.co.in/search?sourceid=chrome&client=ubuntu&channel=cs&ie=UTF-8&q=OSError:+[Errno+2]+No+such+file+or+directory:+'/var/run/xend/boot/boot_kernel.je5fbt'

what can I check next ?
Vm is booting fine with QEMU.
