<![CDATA[XenOrchestra with Terraform]]>Hello! We got some issues with VM's creating using Terraform via XenOrchestra.
We prepared some VM Templates with Packer.
Template VM RAM size: 4 GiB

For example we need to deploy a new VM with 8 GiB RAM. We add required property to .tf file: memory_max = 8394967296

This is doc: https://registry.terraform.io/providers/terra-farm/xenorchestra/latest/docs/resources/vm

After successfuly VM creation we saw that VM has dynamically RAM pool settings: memory min 4 GiB, memory Max: 8 GiB

Could you tell us how to set a fixed memory size for VM using terraform and XenOrchestra?

If target VM has same amount RAM as a template we see dynamically RAM pool with 4 GiB min and 4 GiB max settings.
We tried manually set template size (experiment!) to 128 GiB. We thouhgt that terraform will reduce this value to our target value = 8 GiB. But it failed 😃 VM got 128 GiB RAM and cannot start (Because our host have 128 GiB total mem and other running VM's).

We saw that dynamically memory feature is deprecated. We wanna know hot to solve this.

Thank you.

Here's a snippet of code, it's using a generic Ubuntu 22.04 LTS cloud image template which has 1GB ram by default, in the code I set the memory to 4GB, which works but uses Dynamic rather than static

resource "xenorchestra_vm" "bar" {
    name_label = "TerraformCreatedMe"
    name_description = "Terraform Managed"
    template = data.xenorchestra_template.ubuntu22.id
    memory_max = 4294967296
    cpus  = 4
    destroy_cloud_config_vdi_after_boot = true
    hvm_boot_firmware                   = "uefi"

From the hypervisor side the VM looks like this:

memory-static-max ( RW): 4294967296                         
memory-dynamic-max ( RW): 4294967296
memory-dynamic-min ( RW): 1073741824
memory-static-min ( RW): 1073741824

So to me it looks like memory_max in terraform changes just memory-static-max and memory-dynamic-max which leaves the VM with dynamic memory control.

I want the behaviour to be, when I create a new VM or change the RAM allocation for the VM to have static RAM not dynamic. I hope this is possible.

I'm not sure I understand what happened without seeing a concrete example of the problem.
