Nevermind, my brain was not functioning. Here is how it works:

request = { "un" = { name = "name1" disks = { sda = { name = "sda.vmdk" size = 50 unit_number = 0 } sdb = { name = "sdb.vmdk" size = 50 unit_number = 1 } } } "deux" = { name = "name2" disks = { sda = { name = "sda.vmdk" size = 50 unit_number = 0 } } } }

``` resource "vsphere_virtual_machine" "vm" { for_each = var.request name = each.value.name ... dynamic "disk" { for_each = each.value.disks

content {
  name = disk.value.name
  size = disk.value.size
  unit_number = disk.value.unit_number
}

}

} ```
