-====== Get PXE Knife working with QEMU over HTTP ======+====== Get PxeLinux and 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. +Note : use latest version of Pxelinux to work over HTTP, for me version 3.80 worked.
-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__,​ +Following ​is the way to run Pxe-knife (or any pxelinux ​based system) over http.
-it does not work.+
 <​code> ​ <​code> ​
 qemu -fda gpxe.dsk -net nic -net user -bootp http://​10.0.0.2/​pxeknife/​pxelinux.0 qemu -fda gpxe.dsk -net nic -net user -bootp http://​10.0.0.2/​pxeknife/​pxelinux.0
 </​code>​ </​code>​
-It loads pxelinux.0 successfully,​ but fails in loading ​//pxeknife/default// file with error + 
 +or you can boot the online version of PXE-Knife using following command. 
 +<​code>​  
 +qemu -fda gpxe.dsk -net nic -net user -bootp http://​alien.doesntexist.org/pxeknife/pxelinux.0 
 +</code> 
 + 
 +==== With gpxe embedded script ==== 
 +I recompiled the gpxe with following embedded script ../​contrib/​scripts/​forpxeknife.gpxe, ​
 <​code>​ <​code>​
-TFTP prefix: tftp://10.0.2.2+#!gpxe 
-Trying to loadpxelinux.cfg/​default +echo "Hi, We will be using PXEKnife from URL http://www.alien.doesntexist.org/pxeknife/"​ 
-Unable to locate configuration file+dhcp net0 
 +set 209:string /pxeknife.cfg/​default 
 +set 210:string http://​www.alien.doesntexist.org/​pxeknife/​ 
 +echo "Here we go" 
 +chain http://​www.alien.doesntexist.org/​pxeknife/​pxelinux.0 
 +</​code>​ 
 +and I compile with following command  
 +<​code>​ 
 + make clean && make  EMBEDDED_IMAGE=../​contrib/​scripts/​forpxeknife.gpxe 
 +</​code>​
  
-Boot failed: press a key to retry, or wait for reset...+I execute qemu with no extra parameters at-all. 
 +<​code>​ 
 +qemu -fda gpxe.dsk
 </​code>​ </​code>​
 +
