Set-VMSwitch fails when modify.

[RBadeloe]

Hi there,

I am testing this main.tf on my lab environment with Hyper-V installed.
When I apply the plan at certain moment it stops. This is the error:
Error: run command operation returned code=1
stderr:

stdOut:
Set-VMSwitch : Failed while modifying virtual Ethernet switch connection settings.
At C:\Users\Administrator\AppData\Local\Temp\shell-terraform-1qOARATLNPcbVtvz0wmRsxrSQxY.ps1:52 char:1

  on main.tf line 23, in resource "hyperv_network_switch" "dmz_network_switch":
  23: resource "hyperv_network_switch" "dmz_network_switch" {
  
  

I am using terraform:
Terraform v0.14.9

• provider registry.terraform.io/taliesins/hyperv v1.0.3

Terraform is new for my so I'n not sure what I am doing wrong.

Hey there,

it seems like the powershell command is broken. As soon as you apply the vmmq or vrrs parameters powershell throws that error.

Any chance, that we can disable these parameters in this provider?

My Setup:

• Terraform 1.0.1
• taliesins/hyperv v1.0.3
• Windows Server 2019 (build 17763.1999)

Best regards
Lukas

@Appa-lw and @RBadeloe does your nic support this feature? Are you able to setup this up manually in the hyperv gui?

[Br4v3St4rr]

Yeah it seems that it will fail if your Nic doesn't support it.

Changing the:
Set-VMSwitch @SetVmSwitchArgs

to

Set-VMSwitch @SetVmSwitchArgs -ErrorAction SilentlyContinue | Out-Null

Seems to stop the error and still succeed on the other splatted resources. Not sure if that's good practice or not but it works.

I am getting the same error running the examples (i.e. a basic internal switch):

provider "hyperv" {
  # Configuration options
  user = "XXX"
  password = "YYY"
  host = "localhost"
  port = 5985
  https = false
}

resource "hyperv_network_switch" "dmz_network_switch" {
  name = "dmz"
}

results in:

Terraform will perform the following actions:

  # hyperv_network_switch.dmz_network_switch will be created
  + resource "hyperv_network_switch" "dmz_network_switch" {
      + allow_management_os                     = true
      + default_flow_minimum_bandwidth_absolute = 0
      + default_flow_minimum_bandwidth_weight   = 0
      + default_queue_vmmq_enabled              = false
      + default_queue_vmmq_queue_pairs          = 1
      + default_queue_vrss_enabled              = false
      + enable_embedded_teaming                 = false
      + enable_iov                              = false
      + enable_packet_direct                    = false
      + id                                      = (known after apply)
      + minimum_bandwidth_mode                  = "None"
      + name                                    = "dmz"
      + switch_type                             = "Internal"
    }

Plan: 1 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes
