-====== 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://​​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://​​pxeknife/​pxelinux.0 qemu -fda gpxe.dsk -net nic -net user -bootp http://​​pxeknife/​pxelinux.0
 </​code>​ </​code>​
-It loads pxelinux.0 successfully,​ but fails in loading //​pxeknife/​default//​ file with error  
-TFTP prefix: tftp://​​ 
-Trying to load: pxelinux.cfg/​default 
-Unable to locate configuration file 
-Boot failed: press a key to retry, ​or wait for reset...+or you can boot the online version of PXE-Knife using following command. 
 +qemu -fda gpxe.dsk -net nic -net user -bootp http://​alien.doesntexist.org/​pxeknife/​pxelinux.0
