I have the following variables file:

```auto
variable "vsphere_user" {
  type = string
  default = "terraform@mydomain.local"
}

variable "vsphere_password" {
  type = string
  description = "Terraform AD password"
}

variable "vm_template_name" {
  type = string
  description = "The template to clone to create the VM"
  default = "ROCKY9"
}

variable "root_password" {
  type = string
  description = "Local linux root password"
}

variable vsphere_server {
  type = string
  description = "VMware Server DNS Name"
}

variable vsphere_datacenter {
  type = string
  description = "VMware Datacenter"
}

variable "vsphere_networks" {
  type = map(string)
  description = "A map of VM Networks for different NICs (e.g., nic1, nic2, nic3)"
}

variable vmware-hostnames {
  type = map(string)
  description = "List of VM Names"
}

variable datastores {
  type = map(string)
  description = "List of datastores"
}

variable vm_ips {
  type = map(map(string))
  description = "List of VM IPs"
}

variable vm-count {
  description = "Number of VMs to create"
  type = number
}

variable vsphere_resource_pool {
  description = "VMware Resource Pool"
  type = string
}

variable ipv4_netmasks {
  description = "IPv4 Netmask"
  type = map(number)
}

variable dns_server_list {
  description = "DNS Server List"
  type = list(string)
}

variable ipv4_gateway {
  description = "IPv4 Gateway"
  type = string
}

variable firmware {
  description = "EFI or BIOS"
  type = string
}

variable dns_domain {
  description = "DNS Domain"
  type = string
}

```

And this terraform file:

```auto
provider "vsphere" {
  user = var.vsphere_user
  password = var.vsphere_password
  vsphere_server = var.vsphere_server

  # Allow self signed certs
  allow_unverified_ssl = true
}

data "vsphere_datacenter" "dc" {
  name = var.vsphere_datacenter
}

data "vsphere_datastore" "datastore" {
  name = var.datastores[0]
  datacenter_id = data.vsphere_datacenter.dc.id
}

data "vsphere_network" "nic1" {
  name = var.vsphere_networks["nic1"]
  datacenter_id = data.vsphere_datacenter.dc.id
}

data "vsphere_network" "nic2" {
  name = var.vsphere_networks["nic2"]
  datacenter_id = data.vsphere_datacenter.dc.id
}

data "vsphere_network" "nic3" {
  name = var.vsphere_networks["nic3"]
  datacenter_id = data.vsphere_datacenter.dc.id
}

data "vsphere_virtual_machine" "template" {
  name = var.vm_template_name
  datacenter_id = data.vsphere_datacenter.dc.id
}

data "vsphere_resource_pool" "pool" {
  name = var.vsphere_resource_pool
  datacenter_id = data.vsphere_datacenter.dc.id
}

resource "vsphere_virtual_machine" "vm" {
  count = var.vm-count
  name = var.vmware-hostnames[count.index]
  resource_pool_id = data.vsphere_resource_pool.pool.id
  datastore_id = data.vsphere_datastore.datastore.id

  wait_for_guest_net_timeout = 20

  num_cpus = 4
  memory = 4096
  guest_id = "rockylinux_64Guest"

  scsi_type = "pvscsi"
  firmware = var.firmware

  network_interface {
    network_id = data.vsphere_network.nic1.id
    adapter_type = "vmxnet3"
  }

  network_interface {
    network_id = data.vsphere_network.nic2.id
    adapter_type = "vmxnet3"
  }

  network_interface {
    network_id = data.vsphere_network.nic3.id
    adapter_type = "vmxnet3"
  }

  disk {
    label = "disk0"
    size = 40
    eagerly_scrub = false
    thin_provisioned = true
  }

  cdrom {
    client_device = true

  }

  clone {
    template_uuid = data.vsphere_virtual_machine.template.id
    timeout = "180"
    customize {
      timeout = "180"
      linux_options {
        host_name = var.vmware-hostnames[count.index]
        domain = var.dns_domain
      }
      network_interface {
        ipv4_address = var.vm_ips[count.index]["nic1"]
        ipv4_netmask = var.ipv4_netmasks["nic1"]
        dns_server_list = var.dns_server_list
      }

      network_interface {
        ipv4_address = var.vm_ips[count.index]["nic2"]
        ipv4_netmask = var.ipv4_netmasks["nic2"]
      }

      network_interface {
        ipv4_address = var.vm_ips[count.index]["nic3"]
        ipv4_netmask = var.ipv4_netmasks["nic3"]
      }

      ipv4_gateway = var.ipv4_gateway
    }
  }
}

```

When I connect to the system and run nmtui I see duplicate connections:

ens256  
VMware customization ens256  
ens224  
VMware customization ens224  
ens192  
VMware customization ens192

The two connections seem to be duplicate as far as I can tell. How can I avoid this? Is this a terraform vmware provider issue or a vmware tools issue or a vmware issue? I’ve never had this happen before.

Thanks  
Brad
