Terraform wait_for_ip Flag Returning APIPA Address

dan89

When using Terraform to deploy a Windows VM I need to be able to connect to the host to finalize OS configuration settings. To connect to the host I am using an inline provisioner that is connecting via WinRM with the host connection using the output of the network ipv4 address.

    connection {
      type = "winrm"
      user = var.username
      password = var.password
      host = element(xenorchestra_vm.qa-vm1.network[0].ipv4_addresses, 0)
    }

I set the wait_for_ip flag to true so I could use the returned IP address

resource "xenorchestra_vm" "qa-vm1" {
    cpus = var.cpu
    memory_max = var.memMax
    name_label = var.vmDesc
    name_description = var.vmName
    hvm_boot_firmware = "uefi"
    wait_for_ip = true
    template = data.xenorchestra_template.vm_template.id

but it returns a 169.254.126.62 address and attempts to connect via that address until the apply times out or is cancelled

(remote-exec):   HTTPS: false
(remote-exec):   Insecure: false
(remote-exec):   NTLM: false
(remote-exec):   CACert: false

XCP-NG tools are installed on this host and I can see it reporting the IP address correctly in Xen Orchestra.

Is there a setting I can use to refresh this address so it updates to use the proper DHCP IP of this host or possibly a way to use a sleep timer to wait for the IP to be assigned and show through the XCP-NG tools?

@ddelnano is this something you may be able to help with?

@dan89 yep, I'm the right person for terraform-provider-xenorchestra features or issues

There aren't any settings to accomplish what you are trying to do, but I think that's feasible and would be a nice addition. The current wait_for_ip logic exits once the Xen Orchestra api returns a ip address field. If the vm resource had additional information, say expected_ip_cidr = 10.0.0.0/16, then the provider could continue polling until the DHCP assignment completes.

resource "xenorchestra_vm" "qa-vm1" {
    cpus = var.cpu
    memory_max = var.memMax
    name_label = var.vmDesc
    name_description = var.vmName
    hvm_boot_firmware = "uefi"
    wait_for_ip = true

    expected_ip_cidr = "10.0.0.0/16"  # wait_for_ip will continue to poll until the XO api shows that the VM has an IP in that range

}

Please let me know if this would satisfy your use case and I can probably investigate implementing that over the next few weeks. I'll be creating a GitHub issue for this and linking it here once it's created.

dan89

@ddelnano yes, having an expected CIDR field would cover this use case perfectly.

dan89

@ddelnano do you need any additional information or is this enough to work off of?

ddelnano

@dan89 this is enough to work off and I appreciate your review. Here is the GitHub issue where I'll be tracking the implementation (vatesfr/terraform-provider-xenorchestra#300).

ddelnano

@dan89 this is complete and available in v0.29.0 of the provider.
