boot_command not working

[Gokul-C]

Hi, I have cloned your code and modified your code to work with HyperV-iso builder. I have not touched boot_command. Since it is failing and the Packer is not taking the kickstart files. It is popping up a GUI installer to select the language. While the packer build starts it automatically serve kickstart files via HTTP, I also checked in the browser with IP:PORT here I can see user-data and meta-data file present. I don't know what went wrong. Can you please help me here?

Assuming you are referencing this boot_command (

vagrant-ubuntu/packer/ubuntu-22.04-libvirt/packer.json

Lines 5 to 25 in e38872b

	"boot_command": [
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"<tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>",
	"c<wait5>",
	"set gfxpayload=keep<enter><wait5>",
	"linux /casper/vmlinuz <wait5>",
	"autoinstall quiet fsck.mode=skip <wait5>",
	"net.ifnames=0 biosdevname=0 systemd.unified_cgroup_hierarchy=0 <wait5>",
	"ds=\"nocloud-net;s=http://{{.HTTPIP}}:{{.HTTPPort}}/\" <wait5>",
	"---<enter><wait5>",
	"initrd /casper/initrd<enter><wait5>",
	"boot<enter>"
	],

).

The initial keys pressed are those <tab><tab><tab><tab><tab><tab><tab><tab><tab><tab><wait>, so if you could see something keep typing to the console then these boot_command is passing from packer to the console correctly. Therefore sometime boot_wait may be the root cause, since the VM may take more time to bootup.

If those boot_command seems not passing to the console, then something else from packer + HyperV-iso builder may happened. Therefore you should report the issue to packer.

Yes I can see this packer typing automatically

"set gfxpayload=keep<enter><wait5>", 
   "linux /casper/vmlinuz <wait5>", 
   "autoinstall quiet fsck.mode=skip <wait5>", 
   "net.ifnames=0 biosdevname=0 systemd.unified_cgroup_hierarchy=0 <wait5>", 
   "ds=\"nocloud-net;s=http://{{.HTTPIP}}:{{.HTTPPort}}/\" <wait5>", 
   "---<enter><wait5>", 
   "initrd /casper/initrd<enter><wait5>", 
   "boot<enter>" 

Okay will increase the boot_wait time and share the results here. Thank you so much for your reply.

Would that possible if hyperv default with UEFI mode? If so the boot_command may also need to update accordingly. You could googling with some else UEFI example from github.
