Error: cannot find OS family for guest ID "centos7_64Guest": could not find guest ID "centos7_64Guest"

I have been pulling what little hair I have left trying to solve this. It seems that whenever I add anything in the “customize” block, I get the error above. I am using a CentOS 7.8 template that has been sanitized. Every time I add the customize block, it errors out. I haven’t been able to progress past “terraform plan”. If you have seen this, please let me know. If I take the block out, I can get past the planning phase.

I am using the vSphere provider and trying to create multiple VMs (3 for now) using “count”. I don’t know if that has anything to do with this problem.

main.tf:

# Get the ID of the network to join
data "vsphere_network" "network" {
  name          = var.network_name
  datacenter_id = data.vsphere_datacenter.dc.id
}

# Get the ID of the virtual machine template
data "vsphere_virtual_machine" "template" {
  name          = var.template_name
  datacenter_id = data.vsphere_datacenter.dc.id
}

# Create X number of VMs
resource "vsphere_virtual_machine" "vm" {
  count             = var.vm_count
  name              = "${var.vm_name}-${count.index}"
  folder            = var.vm_folder
  resource_pool_id  = data.vsphere_resource_pool.pool.id
  datastore_id      = data.vsphere_datastore.datastore.id

  num_cpus = data.vsphere_virtual_machine.template.num_cpus
  memory   = data.vsphere_virtual_machine.template.memory
  guest_id = data.vsphere_virtual_machine.template.guest_id

  disk {
    label            = "disk0"
    size             = data.vsphere_virtual_machine.template.disks.0.size
    eagerly_scrub    = data.vsphere_virtual_machine.template.disks.0.eagerly_scrub
    thin_provisioned = data.vsphere_virtual_machine.template.disks.0.thin_provisioned
  }

  network_interface {
    network_id = data.vsphere_network.network.id
  }

  clone {
    template_uuid = data.vsphere_virtual_machine.template.id

    customize {
      linux_options {
        host_name = format("%s-%d", var.vm_name, count.index)
        domain = "mydomain.net"
      }
    }
  }
}

Hi mrpuddin,
I suspect that this is related to the hardware version. Can you check the hardware version on the original template and the supported hardware version by the ESXi.
