Description

With virtual hardware version 17, VMware added a Virtual Watchdog Timer (VWDT). This appears in the vSphere client as an extra piece of hardware that one can add to a VM, but as far as I can see the vsphere provider doesn't support adding one. I suggest that such support should be added to the provider.

Use Case(s)

I want to clone a VM from an Ubuntu Official Cloud Image and modify its virtual hardware for my application. This includes adding a VWDT. At the moment, I have to do this by hand after Terraform has created the VM, but it would be much more convenient if Terraform could customise this the same way it customises the disks, RAM, and virtual hardware version.

Potential Terraform Provider Configuration

VWDTs have a setting to control whether they should be started on boot, so I suspect a block is necessary:

resource "vsphere_virtual_machine" "vm" {
  watchdog_timer {
    run_on_boot = false
  }
  # other properties elided
}
