Default pygrub is failing to boot centos domu on Debian lenny dom0

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
http://farm5.static.flickr.com/4006/4626021351_d1a6f9c014_b.jpg

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.

Shouldn't that be pygrub?

Default pygrub is failing to boot centos domu on Debian lenny dom0

I do not understand why it happens that Debian's user experience is
more than frustrating.
I am finally wiping out all Debian installations from my server.
Assuming that I am not good at Linux or Xen or what ever it is
I will switch to some other commercial Linux distribution.
If you try to do any thing on Debian in a production environment its
just useless.

As a general rule, not being able to solve a problem leads to
frustation. However, the conclusion you reach at is not in any way
following but a subjective *logic*.

BTW, you actually checked the permissions on that bootloader, didn't
you?

Good luck anyway.

I have wiped out all Debian installations I am not going to use Debian
in my life ever.
Why should some one suffer because some thing was poorly written.I do
not find this
problem on some other distros.

I have wiped out all Debian instances from my server.
Thanks for your message I struggled for 2 months.
Here is a snapshot if some one thinks I am a newbie and have not done
my homework
http://farm4.static.flickr.com/3356/4617619327_7f4bfcdb05_o.png
this is not exact thing as my problem was but thanks for your response.
I have wiped out Debian from my server for ever.
I do not have any grudge with Debian but my experience has been more
than frustrating.
I failed to have a CentOS DomU on Debian Dom0 I really really needed
CentOS as one of the Guest OSes.There were more guests running with
Debian but now none of them are there.
You can go through more snapshots here
http://www.flickr.com/photos/48996087@N07/
all of them are on a Debian server.I have finally failed.
Thanks for your response.

In case you ever reconsider, you could try Squeeze. More recent xen packages
are shipped in that branch. The problem you report could have been
already solved.

Best regards.

I believe you have misunderstood me. I mean that instead of *typing* the
errors out by long hand copy the error using the mouse and past it into
your email/bug report. You could instead use the "script" command. This
eliminates the problems which typing out errors can cause.
