How to use multiple target nodes?

[lug-gh]

Hello, in version v3.0.1-rc1 “multiple target nodes” were introduced. However, I cannot find a way to use this function, and unfortunately there is nothing in the documentation.

Based on the source code Nodes: strings.Split(itemMap["nodes"].(string), ","), , I assume that I have to submit the hosts as a string, separated by a comma. target_node = "pve1,pve2,pve3"

However, I then get the error "Error: 400 Parameter verification failed." when applying.
It is displayed in the plan without any problems.

This issue is still open, right? This is the actual code behind the field "target_nodes":

			"target_nodes": {
				Type:     schema.TypeList,
				Optional: true,
				Elem: &schema.Schema{
					Type: schema.TypeString,
				},
				Description: "A list of nodes where VM goes to",
			},

@PascalKu Thank you for pointing out that the “multiple hosts” configuration has a different name. I assumed that it would stay with “target_host” (without the s at the end).

terraform-provider-proxmox/proxmox/resource_vm_qemu.go

Lines 133 to 145 in 8e4bad1

	"target_node": {
	Type: schema.TypeString,
	Optional: true,
	Description: "The node where VM goes to",
	},
	"target_nodes": {
	Type: schema.TypeList,
	Optional: true,
	Elem: &schema.Schema{
	Type: schema.TypeString,
	},
	Description: "A list of nodes where VM goes to",
	},

I have now invested a lot of time in various tests, only to find out that the “target_node” functionality is currently broken for existing VMs anyway.

I remember that in the past, if a VM was on a node that did not match the target_host config, that VM would be moved. This is currently completely ignored, which is why “target_nodes” currently has no function.
In addition, target_nodes requires target_node, if this option is missing, terraform fails.
