| - | - | + | - You will also need PXELinux [[http://syslinux.zytor.com/wiki/index.php/PXELINUX]] |
| + | <code> | ||
| + | $ mkdir /home/myname/for_pxe_knife/ | ||
| + | $ wget http://pxeknife.erebor.org/releases/pxeknife-0.0.2.tar.gz | ||
| + | $ cd /home/myname/for_pxe_knife/ | ||
| + | $ tar -xvf ../pxeknife-0.0.2.tar.gz | ||
| + | $ cp /usr/lib/syslinux/pxelinux.0 . | ||
| + | $ cp /usr/lib/syslinux/*.c32 . | ||
| + | $ cp /usr/lib/syslinux/memdisk . | ||
| + | $ mkdir pxelinux.cfg | ||
| + | $ vi pxelinux.cfg/default | ||
| + | </code> | ||
| + | |||
| + | Now, the content of my //pxelinux.cfg/default// file is | ||
| + | <code> | ||
| + | DEFAULT menu.c32 | ||
| + | PROMPT 0 | ||
| + | TIMEOUT 100 #this is optional - will start the default after 10 seconds | ||
| + | MENU TITLE --== Main Menu ==-- | ||

| + | LABEL bootlocal | ||
| + | MENU DEFAULT | ||
| + | MENU LABEL Local Boot | ||
| + | localboot 0 | ||
| + | |||
| + | |||
| + | #load pxe knife | ||
| + | LABEL pxeknife | ||
| + | MENU LABEL PXE Knife ---> | ||
| + | kernel menu.c32 | ||
| + | append pxeknife/pxeknife.conf | ||
| + | </code> | ||
| + | |||
| + | <code> | ||
| + | $ cd gpxe/bootables/ | ||
| + | $ qemu-img create -f raw testing.img 10M | ||
| + | </code> | ||
| + | |||
| + | Here is the code which is working for | ||
| + | <code> | ||
| + | $ qemu -net nic -net user -boot n -hda ./testing.img -bootp /pxelinux.0 -tftp /home/myname/for_pxe_knife/ | ||
| + | $ qemu -net nic -net user -fda ./gpxe.dsk -bootp /pxelinux.0 -tftp /home/myname/for_pxe_knife/ | ||
| + | </code> | ||
| + | for following version of qemu version qemu version 0.10.0 | ||
| + | <code> | ||
| + | $ qemu | ||
| + | QEMU PC emulator version 0.10.0, Copyright (c) 2003-2008 Fabrice Bellard | ||
| + | </code> | ||
| + | |||
| + | ==== Problems ==== | ||
| + | |||
| + | As per me following command should have worked, but It did not worked | ||
| + | |||
| + | <code> | ||
| + | $ qemu -bootp tftp://10.0.2.2//pxelinux.0 -tftp /home/myname/for_pxe_knife/ -fda gpxe.dsk | ||
| + | </code> | ||
| + | at same time command | ||
| + | <code> | ||
| + | $ qemu -bootp /pxelinux.0 -tftp /home/myname/for_pxe_knife/ -fda gpxe.dsk | ||
| + | </code> | ||
| + | works. | ||
| + | |||
| + | Problem faced is,\\ | ||
| + | it successfully downloads the //pxelinux.0// and executes it, | ||
| + | but it fails when it is downloading pxelinux.cfg/default\\ | ||
| + | It gives an error saying | ||
| + | <code> | ||
| + | TFTP prefix: tftp://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> | ||
| + | |||
| + | |||
| + | Note : There are some versions of qemu for which network boot option did not worked. | ||
| + | <code> | ||
| + | $ qemu -net nic -net user -boot n -hda ./testing.img -bootp /pxelinux.0 -tftp /home/minix-pravin/Etherboot/v2/pxeknife/pxeknife/ | ||
| + | No valid PXE rom found for network device | ||
| + | </code> | ||
| + | Above error came for qemu version 0.9.1 | ||
| + | <code> | ||
| + | $ qemu | ||
| + | QEMU PC emulator version 0.9.1, Copyright (c) 2003-2008 Fabrice Bellard | ||
| + | </code> | ||
| + | |||
| + | But if you provide gpxe.dsk instead of ./testing.img it uses gpxe.dsk stack and boots properly. | ||
| + | <code> | ||
| + | $ qemu -net nic -net user -fda ./gpxe.dsk -bootp /pxelinux.0 -tftp /home/minix-pravin/Etherboot/v2/pxeknife/pxeknife/ | ||
| + | </code> | ||
