Thanks @olivierlambert for posting this. I'm using the same script to create a template through Packer and then through Terraform I want to create multiple VMs on xen-server. But I want to use two different disks (one for OS, one for APP data), so how can I define that? and should be defined in Packer script or Terraform script? Thanks

Is there support for a pre downloaded ISO already in a ISO SR?

@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 😄
