Can't attach more than one NIC from the same vnet

[alvarocurt]

Description

A project requires us to deploy VMs with multiple NICs in the same network, with different asigned IPs.
However, the terraform provider doesn't seem to allow us to do that.

Terraform and Provider version

Terraform v1.9.7
on linux_amd64

• provider registry.terraform.io/opennebula/opennebula v1.4.0

Affected resources and data sources

opennebula_virtual_machine
opennebula_virtual_network

Terraform configuration

resource "opennebula_virtual_machine" "loadcore_agent-dn1" {
  name        = "reference-loadcore_agent-dn1"
  template_id = 162
  cpu         = 4
  vcpu        = 4
  memory      = 8192

  context = {
    NETWORK = "YES"
    SET_HOSTNAME = "$NAME"
    USERNAME = "jenkins"
  }

  nic {
    model           = "virtio"
    network_id      = opennebula_virtual_network.vnet-private_oneKE.id
  }
  nic {
    model           = "virtio"
    network_id      = opennebula_virtual_network.vnet-private_oneKE.id
  }

}

Expected behavior

Deploys a VM with 2 NICs in vnet vnet-private_oneKE

Actual behavior

│ Error: Duplicate object key
│
│   on tf-loadcore_agent-dn1.tf line 34, in output "loadcore_agent-dn1-ips":
│   34:   value = { for nic in opennebula_virtual_machine.loadcore_agent-dn1.nic[*] : nic.network_id => nic.computed_ip }
│     ├────────────────
│     │ nic.network_id is 603
│
│ Two different items produced the key "603" in this 'for' expression. If duplicates are expected, use the ellipsis (...) after the value expression to enable grouping by key.

Steps to Reproduce

Create a vnet and try deploying a VM with 2 NICs from it.
