I already make a bootable auto install ISO of ubuntu 22.04 server , and now I want to provide it in my original PXE environment

my PXE IP: 192.168.11.7

hereis my dhcpd.conf about pxelinux

 filename "bios/pxelinux.0";
    next-server 192.168.11.7;

and then add this section in my pxe boot menu

label Ubuntu 22.04 Server auto install
menu label Ubuntu 22.04 Server auto install
kernel tftp://192.168.11.7/images/ubuntu/22.04/amd64/vmlinuz
initrd tftp://192.168.11.7/images/ubuntu/22.04/amd64/initrd.gz
append ip=dhcp cloud-config-url=/dev/null url=http://192.168.11.7/jammy-server/ubuntu-22.04-live-server-amd64.iso autoinstall ds=nocloud-net;s=http://192.168.11.7/jammy-server/ # Don't forget the slash at the end.

then upload ISO file , vmlinuz/initrd.gz (extracted from the ISO ) , user-data/meta-data ( which I make ) to http://192.168.11.7/jammy-sever/

enter image description here

all these files can be downloaded.

then I restart dhcp service , tftpd service , nginx service , create a VM in proxmox to see if PXE works , here is the screen recording.

the installer just hangs here like forever , althrouuogh I can start new tty with alt+f2/f3/f4... but it's all black screen , so I can't see the installer log ( if there is any ) to see what's going on.

I'm stuck here for couple days , I really need some advice to move on. Any advice will be appreciated.

  • How much RAM does the VM in proxmox have? I found 3GB of RAM is needed when using the 22.04 live-server installer over PXE. With too little RAM the machine simply hangs. – Andrew Lowther Jun 17 '22 at 16:13
  • 8GB RAM , and would you please consider to share how to configure PXE to deploy 22.04 ? – Eric Chang Jun 18 '22 at 03:02
  • The 22.04 process should be nearly identical to the 20.04 process (https://askubuntu.com/a/1240068/376778). You video shows errors starting at cloud-init-local.service. This is before the user-data file would be downloaded, but if the Proxmox VM has a local config (e.g. cicustom value) it could be breaking something. – Andrew Lowther Jun 19 '22 at 18:47
  • You can also try to PXE boot without the autoinstall ds=... arguments to see if the interactive installer starts properly. – Andrew Lowther Jun 19 '22 at 19:10
  • without autoinstall part , kernel panic.

  • That kernel panic usually means the initrd line is missing or wrong. Without the initramfs the kernel does not have the modules needed for the file system. It is hard to say for certain without more information. I saw your other post saying you got a Proxmox VM working with PXE and autoinstall, so I hope that means you figured out your problem. – Andrew Lowther Jun 22 '22 at 01:37
