Modifications needed for iPXE to run

[NetworkTest]

Thanks for the pve-iso-2-pxe script, which worked fine.

The iPXE bootscript would not run without two modifications:

1. The script should set a "webserver" variable instead of "ipserver" since the script calls "${webserver}" later on.

set webserver http://192.168.1.1

2. The iPXE client loaded initrd OK but then returned file-not-found errors when trying to load linux26 with options. I think the syntax, with spaces, is an issue. My workaround was to change the "opts" value into the form of a PHP query, starting with a "?" and then delimiting each key/value pair with an "&" character:

set opts "?vga=791&video=vesafb:ywrap,mtrr&ramdisk_size=16777216&rw&quiet&initrd=initrd"
..
set kernel "${webserver}/proxmox/${pveversion}/linux26${opts}&splash=silent

Note the lack of spaces in the "set kernel" line.

Thanks again.

The example boot script should look like this:

#!ipxe
dhcp
set webserver http://192.168.1.1
set opts ?vga=791&video=vesafb:ywrap,mtrr&ramdisk_size=16777216&rw&quiet&initrd=initrd
menu Please choose an operating system to boot
    item normal Install Proxmox
    item debug Install Proxmox (Debug Mode)
choose --default normal --timeout 5000 target && goto ${target}
:debug
    set kernel ${webserver}/pxeboot/linux26${opts}&splash=verbose&proxdebug
    goto init
:normal
    set kernel ${webserver}/pxeboot/linux26${opts}&splash=silent
    goto init
:init
initrd ${webserver}/pxeboot/initrd
chain ${kernel}

just tried with latest ipxe and PVE 8.2, for me it still works without the quoting and just spaces like this:

#!ipxe

set base-url http://....

menu Installer
item --gap --
item pve PVE
choose target && goto ${target}

:pve
set pve-version 8.1
initrd ${base-url}/proxmox/${pve-version}/initrd.iso.img
chain ${base-url}/proxmox/${pve-version}/linux26 vga=791 video=vesafb:ywrap,mtrr ramdisk_size=16777216 rw quiet splash=silent initrd=initrd.iso.img
boot

@morph027 same setup with an uefi boote machine and proxmox-ve_8.2-2.iso but my zfs single disk manual installation is failing to complete with: popup in GUI:

bootloader setup errors:
- unable to update boot loader config

and ctrl-alt-F2

/sbin/grub-mkconfig: 1: /etc/default/grub.d/installer.cfg: : Permission denied
bootloader setup errors:
- unable to update boot loader config

I have been able to install 8.1-2 manually from the pve-iso-2-pxe generated files although the bootloader installation complains but it did install (with zfs).

ymmv, with the embeded iso I had just had to type "exit" at the command line prompt. The machine will proceed to umount/reboot and is funtionnal after.

I have no doubt that it would work in the event that your drivers are satisfied by the initrd and not whatever process the installer uses when it says: "installing additional hardware drivers". I noticed that part doesn't take place when you PXE boot the image.. which is what I was asking about.
