Is this enough or maybe I need to paste the whole dump somewhere? Theres a LOT of debug output.

I was trying to boot flatcar linux diskless too, but then realised I probably need a disk anyway. So there is a disk on all VMs now.

The template is just the default "Other media" diskless template that came with XO.

# get "other" template id from pool per vm
data "xenorchestra_template" "other" {
  for_each   = var.hosts
  name_label = "Other install media"
  pool_id    = each.value.pool_id
}

resource "xenorchestra_vm" "flatcar" {
  for_each            = var.hosts
  auto_poweron        = true
  installation_method = "network"
  name_label          = each.key
  memory_max          = each.value.memory * 1024 * 1024 * 1024
  cpus                = each.value.cores
  name_description = format("tf-flatcar: %dC %dMiB %dG",
    each.value.cores,
    each.value.memory * 1024,
  contains(keys(each.value), "disk") ? each.value.disk : 0)
  template = data.xenorchestra_template.other[each.key].id
  tags     = []
  network {
    network_id = var.net.id
  }
  lifecycle {
    ignore_changes = [
      destroy_cloud_config_vdi_after_boot,
      disk,
      template,
      vga,
      videoram,
      affinity_host,
    ]
  }

  # possibly support diskless flatcar in the future
  disk {
    sr_id            = contains(keys(each.value), "disk") ? var.sr.id : "xxx"
    name_label       = contains(keys(each.value), "disk") ? format("%s-root", each.key) : "xxxx"
    name_description = contains(keys(each.value), "disk") ? format("%s-root", each.key) : "xxxx"
    size             = contains(keys(each.value), "disk") ? each.value.disk * 1024 * 1024 * 1024 : 0
  }
  timeouts {}
}

variable "hosts" {
  type = map(object({
    cores   = number
    memory  = number # in G
    disk    = number # in G
    pool_id = string
  }))
}

Using terraform module and creating a VM with diskless template and installation_method = "network" causes some problem. I worked around it by modifying the terraform module as follows:

XOA: Current version: 5.86.1
Terraform Provider version 0.25.1

default

vm.create
{
  "CPUs": 4,
  ..
  "installation": {
    "method": "network",
    "repository": ""
  },
  "memoryMax": 6442450944,
  ..
}
{
  "code": 10,
  "data": {
    "errors": [
      {
        "instancePath": "/installation/repository",
        "schemaPath": "#/properties/installation/properties/repository/minLength",
        "keyword": "minLength",
        "params": {
          "limit": 1
        },
        "message": "must NOT have fewer than 1 characters"
      }
    ]
  },
  "message": "invalid parameters",
  "name": "XoError",
  "stack": "XoError: invalid parameters
    at Module.invalidParameters (/usr/local/lib/node_modules/xo-server/node_modules/xo-common/src/api-errors.js:21:32)
    at Xo.call (file:///usr/local/lib/node_modules/xo-server/src/xo-mixins/api.mjs:65:20)
    at Api.#callApiMethod (file:///usr/local/lib/node_modules/xo-server/src/xo-mixins/api.mjs:413:19)"
}

nulled out "repository"

vm.create
{
  "CPUs": 4,
  ..
  "installation": {
    "method": "network"
  },
  "memoryMax": 6442450944,
  ..
}
{
  "code": 10,
  "data": {
    "errors": [
      {
        "instancePath": "/installation",
        "schemaPath": "#/properties/installation/required",
        "keyword": "required",
        "params": {
          "missingProperty": "repository"
        },
        "message": "must have required property 'repository'"
      }
    ]
  },
  "message": "invalid parameters",
  "name": "XoError",
  "stack": "XoError: invalid parameters

    at Api.#callApiMethod (file:///usr/local/lib/node_modules/xo-server/src/xo-mixins/api.mjs:413:19)"
}

For some reason I typed repository: "none". In next test and that worked fine, and I dont have the log for that. I think maybe XO should accept the nulled repository field or empty string what the terraform module is producing now, if "method: network" is specified.
