@chrispro-21 yes!

First, check that you have the SR name is defined:

variable "sr_iso_name" {
  type        = string
  default     = "ISO Repository"
  description = "The ISO-SR to packer will use"
}

Then, you can use iso_name = "debian-12.5.0-amd64-netinst.iso" directly instead of the URL of the ISO.

Awesome! That works! Thank you very much!

Thanks to @AtaxyaNetwork for the tip 😄

Hi @olivierlambert and Everyone else,

I am facing an issue.
I don't have DHCP server who can assign IP automatically.
So I am trying to use Static IP in my boot command like below to make internet available.

###########################################################
http_directory = "http"
ip_getter = "http"

boot_command = [
"",
"/install.amd/vmlinuz ",
"initrd=/install.amd/initrd.gz ",
"auto=true ",

Static networking required BEFORE fetching preseed (no DHCP available)

"netcfg/disable_autoconfig=true ",
"netcfg/disable_dhcp=true ",
"netcfg/choose_interface=auto ",
"netcfg/get_ipaddress=16x.1x.1xx.2xx ",
"netcfg/get_netmask=2xx.255.2xx.2xx ",
"netcfg/get_gateway=1xx.6x.x.x ",
"netcfg/get_nameservers=2xx.1xx.xx.xx ",
"netcfg/confirm_static=true ",
"domain= ",
"url=http://{{.HTTPIP}}:{{.HTTPPort}}/preseed.cfg ",
"hostname=debian ",
"interface=auto ",
"vga=788 noprompt quiet--- "
]
###########################################################

Same setting I have added in preseed file also.
But the issue is that my IP is binded to a MAC address. So I need to change the MAC address of newly created instance by packer also.
How I can achieve that? Any urgent help will be appreciated.
