Terraform Provider for Microsoft Hyper-V

Requirements

• Terraform 0.10.x
• Go 1.8 (to build the provider plugin)
• Powershell 5

hyperv_virtual_machine

Create a virtual machine.

Example Usage with Differencing Disks (Recommended)

  username              = "hv_administrator"
  password              = "Password1234!"
}

resource "hyperv_virtual_switch" "application_switch" {
  name  = "application_switch"
}

  cpu                   = 4
  ram_mb                = 4096
  switch                = "external_switch"
  disable_network_boot  = true
  path                  = "C:\\ClusterStorage\\VMs"

  network_adapter {
    name = "inside",
    switch_name = "inside",
  },

  storage_disk {
    name                  = "boot"
    diff_parent_path      = "C:\\ClusterStorage\\VHDs\\server2012r2-0.1.0.vhdx"
  }
}

Argument Reference

The following arguments are supported:

• name - (Required) The name of the virtual machine resource.
• switch - (Required) The name of the virtual switch that the virtual machine will connect to.
• path - (Optional) The directory to store the files for the new virtual machine, defaults to C:\HyperV.
• processors - (Optional) The number of Virtual Processors to assign to the virtual machine, defaults to 2.
• vlan_id - (Optional) Specifies the virtual LAN identifier of the virtual machine network adapter.
• mac - (Optional) The mac address of the virtual machines network adapter.
• disable_network_boot - (Optional) Removes network devices from the BIOS boot sequence, this saves time when multiple adapters are used.
• disable_secure_boot - (Optional) Specifies whether to disable secure boot.
• generation - (Optional) Specifies the generation, as an integer, for the virtual machine. The values that are valid are 1 and 2, defaults to 2
• ram - (Optional) An integer representing the amount of RAM allocated to the VM in MB, defaults to 2048
• wait_for_ip - (Optional) Polls the HyperV host for the guest VM's IP address. If an IP address is detected, the host property of the provisioners connection is set. The wait_for_ip block is documented below.
• storage_disk - (Optional) The storage_disk block is documented below.
• network_adapter - (Optional) The network_adapter block is documented below.

wait_for_ip Supports the following:

• timeout - (Optional) Time in minutes to wait for an IP, an error will be generated if an IPv4 address is not detected after timeout minutes, defaults to 5
• adapter_name - (Required) The name of the network adapter to query, defaults to Network Adapter

The use of wait_for_ip is discouraged it increases the chance of createing a zombie resource

storage_disk supports the following:

• name - (Required) Name of the VHDX, this must be unique.
• image_path - (Optional) A local directory on the HyperV host containing a VHDX image. For example C:\ClusterStorage\VHDs\windows2012r2-0.0.1.vhdx. image_path cannot be used with image_url or diff_parent_path
• image_url - (Optional) Specifies an image to download. For example http://aritfactory.local/generic/windows2012r2-0.0.1.vhdx. image_url cannot be used with image_path or diff_parent_path.
• diff_parent_path - (Optional) A local directory on the HyperV host containing a VHDX image, this image will be used as the parent and a new differencing disk will created. diff_parent_path cannot be used with image_url or image_path
• size - (Optional) The size in MB when creating a new vhdx. A new vhdx will be created if neither diff_parent_path, image_url or image_path are specified, default is 50

network_adapter supports the following:

• name - (Required) The name of the network adapter.
• switch_name - (Required) The virtual switch to connect the network adapter to,
• vlan_id - (Optional) Specifies the virtual LAN identifier of the virtual machine network adapter.
• mac - (Optional) he MAC address of this network adapter, must not contain any special characters.

Attributes Reference

The following attributes are exported:

• id - The virtual machine ID.

Example Using a Provisioner With wait_for_ip Enabled (Not recommended)

resource "hyperv_virtual_machine" "db" {
  vm_name               = "db"
  processors            = 4
  ram_mb                = 4096
  switch                = "external_switch"
  disable_network_boot  = true
  path                  = "C:\\ClusterStorage\\VMs"
  wait_for_ip           = true

  storage_disk {
    name                  = "boot"
    diff_parent_path      = "C:\\ClusterStorage\\VHDs\\server2012r2-0.1.0.vhdx"
  }

  provisioner "remote-exec" {
    inline = ["powershell.exe -executionpolicy unrestricted Write-Host Hello World!"],

    connection {
      type      = "winrm"
      user      = "Administrator"
      password  = "Password1234!"
      timeout   = "5m"
    }
  }
}

Example Using a Provisioner with wait_for_ip Disabled (recommended)

In order for this to work, you will need to provide the VM with either a static IP or DHCP binding and DNS entry.

resource "hyperv_virtual_machine" "db" {
  vm_name               = "db"
  processors            = 4
  ram_mb                = 4096
  switch                = "external_switch"
  disable_network_boot  = true
  path                  = "C:\\ClusterStorage\\VMs"

  storage_disk {
    name                  = "boot"
    diff_parent_path      = "C:\\ClusterStorage\\VHDs\\server2012r2-0.1.0.vhdx"
  }

  provisioner "remote-exec" {
    inline = ["powershell.exe -executionpolicy unrestricted Write-Host Hello World!"],

    connection {
      type      = "winrm"
      host      = "db.contoso.local"
      user      = "Administrator"
      password  = "Password1234!"
      timeout   = "5m"
    }
  }
}
