====== Get PXE Knife working with QEMU over HTTP ======

I am taking similar approach as I took for TFTP for which QEMU + PXE Knife combination is working if I use qemu TFTP stack.
Here are the things that are working for me.
<code>
qemu -net nic -net user -fda ./gpxe.dsk -bootp /pxelinux.0 -tftp /home/myname/for_pxe_knife/
</code>
which boots pxe-knife over tftp and 
<code>
qemu -fda gpxe.dsk -net nic -net user -bootp http://10.0.0.2/gpxe/gtest.gpxe
</code>
boots gtest.gpxe which is copy of [[http://etherboot.org/gtest/gtest.gpxe]].\\

But when I try and use HTTP with qemu over pxe_knife which is based on __pxelinux__,
it does not work.
<code> 
qemu -fda gpxe.dsk -net nic -net user -bootp http://10.0.0.2/pxeknife/pxelinux.0
</code>
It loads pxelinux.0 successfully, but fails in loading //pxeknife/default// file with error 
<code>
TFTP prefix: http://10.0.2.2/
Trying to load: pxelinux.cfg/default
Unable to locate configuration file

Boot failed: press a key to retry, or wait for reset...
</code>

==== With gpxe embedded script ====
I recompiled the gpxe with following embedded script, 

<code>
#!gpxe
echo "Hi there"
dhcp net0
set 209:string pxelinux.cfg/default
set 210:string http://10.0.0.2/pxeknife/
chain http://10.0.0.2/pxeknife/pxelinux.0
boot
</code>

I execute qemu with no extra parameters atall.
<code>
qemu -fda gpxe.dsk
</code>
I do get my echo messages printed, but still I am getting same error.
