Migrating VM from one node to another.

[TafkaMax]

Hi I am using the migrate=true option with the proxmox provider and I am testing to see if I can move a VM from one node to another and I am getting this error.

I am using the latest opentofu.

tofu plan

  # module.proxmox-vm.proxmox_virtual_environment_vm.instances["test-vm-02"] will be updated in-place
  ~ resource "proxmox_virtual_environment_vm" "instances" {
        id                      = "100"
        name                    = "test-vm-02"
      ~ node_name               = "proxmox-02" -> "proxmox-01"
        tags                    = [
            "debian",
            "terraform",
        ]
        # (28 unchanged attributes hidden)

        # (8 unchanged blocks hidden)
    }

tofu apply

module.proxmox-vm.proxmox_virtual_environment_vm.instances["test-vm-02"]: Modifying... [id=100]

After running tofu plan apply again, it shows though that everything is OK.

Hey @TafkaMax 👋🏼
It looks like a timing issue, the VM was still migrating when the provider was asking the new node about the VM config. Then by the the time of re-apply everything was in place.

Hi thanks for the reply! That's what I thought. Is there a way to mitigate this race condition?

Not at the moment, we'd need a code change.
