# Hyper-V Builder (from an ISO)

Type: `hyperv-iso`

The Hyper-V Packer builder is able to create
[Hyper-V](https://www.microsoft.com/en-us/server-cloud/solutions/virtualization.aspx)
virtual machines and export them, starting from an ISO image.

The builder builds a virtual machine by creating a new virtual machine from
scratch. Typically, the VM is booted, an OS is installed, and software is
provisioned within the OS. Finally the VM is shut down. The result of the
Hyper-V builder is a directory containing all the files necessary to run
the virtual machine portably.

## Basic Example

Here is a basic example. This example is not functional. It will start the OS
installer but then fail because we don't provide the preseed file for Ubuntu
to self-install. Still, the example serves to show the basic configuration:

``` json
{
  "type": "hyperv-iso",
  "iso_url": "http://releases.ubuntu.com/12.04/ubuntu-12.04.5-server-amd64.iso",
  "iso_checksum": "769474248a3897f4865817446f9a4a53",
  "iso_checksum_type": "md5",
  "ssh_username": "packer",
  "ssh_password": "packer",
  "shutdown_command": "echo 'packer' | sudo -S shutdown -P now"
}
```

By default Packer will perform a hard power off of a virtual machine.
However, when a machine is powered off this way, it is possible that
changes made to the VMs file system may not be fully synced, possibly
leading to corruption of files or lost changes. As such, it is important to
add a `shutdown_command`. This tells Packer how to safely shutdown and
power off the VM.

## Configuration Reference

There are many configuration options available for the Hyper-V builder. They
are organized below into two categories: required and optional. Within each
category, the available options are alphabetized and described.

In addition to the options listed here, a
[communicator](/docs/templates/communicator.html) can be configured for this
builder.

### Required:

-   `iso_checksum` (string) - The checksum for the ISO file or virtual
    hard drive file. The algorithm to use when computing the checksum is
    specified with `iso_checksum_type`.

-   `iso_checksum_type` (string) - The algorithm to be used when computing
    the checksum of the file specified in `iso_checksum`. Currently, valid
    values are "none", "md5", "sha1", "sha256", or "sha512". Since the
    validity of ISO and virtual disk files are typically crucial to a
    successful build, Packer performs a check of any supplied media by
    default. While setting "none" will cause Packer to skip this check,
    corruption of large files such as ISOs and virtual hard drives can
    occur from time to time. As such, skipping this check is not
    recommended.

-   `iso_url` (string) - A URL to the ISO containing the installation image or
    virtual hard drive (VHD or VHDX) file to clone. This URL can be either an
    HTTP URL or a file URL (or path to a file). If this is an HTTP URL, Packer
    will download the file and cache it between runs.

### Optional:

-   `boot_command` (array of strings) - This is an array of commands to type
    when the virtual machine is first booted. The goal of these commands
    should be to type just enough to initialize the operating system
    installer. Special keys can be typed as well, and are covered in the
    section below on the boot command. If this is not specified, it is assumed
    the installer will start itself.

-   `boot_wait` (string) - The time to wait after booting the initial virtual
    machine before typing the `boot_command`. The value specified should be
    a duration. For example, setting a duration of "1m30s" would cause
    Packer to wait for 1 minute 30 seconds before typing the boot command.
    The default duration is "10s" (10 seconds).

-   `cpu` (number) - The number of CPUs the virtual machine should use. If
    this isn't specified, the default is 1 CPU.

-   `differencing_disk` (boolean) - If true enables differencing disks. Only
    the changes will be written to the new disk. This is especially useful if
    your source is a VHD/VHDX. This defaults to `false`.

-   `disk_additional_size` (array of integers) - The size or sizes of any
    additional hard disks for the VM in megabytes. If this is not specified
    then the VM will only contain a primary hard disk. Additional drives
    will be attached to the SCSI interface only. The builder uses
    expandable rather than fixed-size virtual hard disks, so the actual
    file representing the disk will not use the full size unless it is
    full.

-   `disk_block_size` (string) - The block size of the VHD to be created.
    Recommended disk block size for Linux hyper-v guests is 1 MiB. This
    defaults to "32 MiB".

-   `disk_size` (number) - The size, in megabytes, of the hard disk to create
    for the VM. By default, this is 40 GB.

-   `enable_dynamic_memory` (boolean) - If `true` enable dynamic memory for
    the virtual machine. This defaults to `false`.

-   `enable_mac_spoofing` (boolean) - If `true` enable MAC address spoofing
    for the virtual machine. This defaults to `false`.

-   `enable_secure_boot` (boolean) - If `true` enable secure boot for the
    virtual machine. This defaults to `false`. See `secure_boot_template`
    below for additional settings.

-   `enable_virtualization_extensions` (boolean) - If `true` enable
    virtualization extensions for the virtual machine. This defaults to
    `false`. For nested virtualization you need to enable MAC spoofing,
    disable dynamic memory and have at least 4GB of RAM assigned to the
    virtual machine.

-   `floppy_dirs` (array of strings) - A list of directories to place onto
    the floppy disk recursively. This is similar to the `floppy_files` option
    except that the directory structure is preserved. This is useful for when
    your floppy disk includes drivers or if you just want to organize it's
    contents as a hierarchy. Wildcard characters (\*, ?, and \[\]) are
    allowed. The maximum summary size of all files in the listed directories
    are the same as in `floppy_files`.

-   `floppy_files` (array of strings) - A list of files to place onto a floppy
    disk that is attached when the VM is booted. This is most useful for
    unattended Windows installs, which look for an `Autounattend.xml` file on
    removable media. By default, no floppy will be attached. All files listed
    in this setting get placed into the root directory of the floppy and the
    floppy is attached as the first floppy device. Currently, no support
    exists for creating sub-directories on the floppy. Wildcard characters
    (`*`, `?`, and `[]`) are allowed. Directory names are also allowed, which
    will add all the files found in the directory to the floppy.

-   `generation` (number) - The Hyper-V generation for the virtual machine. By
    default, this is 1. Generation 2 Hyper-V virtual machines do not support
    floppy drives. In this scenario use `secondary_iso_images` instead. Hard
    drives and DVD drives will also be SCSI and not IDE.

-   `guest_additions_mode` (string) - If set to `attach` then attach and
    mount the ISO image specified in `guest_additions_path`. If set to
    `none` then guest additions are not attached and mounted; This is the
    default.

-   `guest_additions_path` (string) - The path to the ISO image for guest
    additions.

-   `headless` (boolean) - Packer defaults to building Hyper-V virtual
    machines by launching a GUI that shows the console of the machine being
    built. When this value is set to true, the machine will start without a
    console.

-   `http_directory` (string) - Path to a directory to serve using Packers
    inbuilt HTTP server. The files in this directory will be available
    over HTTP to the virtual machine. This is useful for hosting kickstart
    files and so on. By default this value is unset and the HTTP server is
    not started. The address and port of the HTTP server will be available
    as variables in `boot_command`. This is covered in more detail below.

-   `http_port_min` and `http_port_max` (number) - These are the minimum and
    maximum port to use for the HTTP server started to serve the
    `http_directory`. Since Packer often runs in parallel, a randomly
    available port in this range will be repeatedly chosen until an
    available port is found. To force the HTTP server to use a specific
    port, set an identical value for `http_port_min` and `http_port_max`.
    By default the values are 8000 and 9000, respectively.

-   `iso_target_extension` (string) - The extension of the ISO file after
    download. This defaults to "iso".

-   `iso_target_path` (string) - The path where the ISO should be saved after
    download. By default the ISO will be saved in the Packer cache
    directory with a hash of the original filename as its name.

-   `iso_urls` (array of strings) - Multiple URLs for the ISO to download.
    Packer will try these in order. If anything goes wrong attempting to
    download or while downloading a single URL, it will move on to the next.
    All URLs must point to the same file (same checksum). By default this is
    empty and `iso_url` is used. Only one of `iso_url` or `iso_urls` can be
    specified.

-   `mac_address` (string) - This allows a specific MAC address to be used on
    the default virtual network card. The MAC address must be a string with
    no delimiters, for example "0000deadbeef".

-   `output_directory` (string) - This setting specifies the directory that
    artifacts from the build, such as the virtual machine files and disks,
    will be output to. The path to the directory may be relative or
    absolute. If relative, the path is relative to the working directory
    `packer` is executed from. This directory must not exist or, if
    created, must be empty prior to running the builder. By default this is
    "output-BUILDNAME" where "BUILDNAME" is the name of the build.

-   `ram_size` (number) - The amount, in megabytes, of RAM to assign to the
    VM. By default, this is 1 GB.

-   `secondary_iso_images` (array of strings) - A list of ISO paths to
    attach to a VM when it is booted. This is most useful for unattended
    Windows installs, which look for an `Autounattend.xml` file on removable
    media. By default, no secondary ISO will be attached.

-   `secure_boot_template` (string) - The secure boot template to be
    configured. Valid values are "MicrosoftWindows" (Windows) or
    "MicrosoftUEFICertificateAuthority" (Linux). This only takes effect if
    `enable_secure_boot` is set to "true". This defaults to "MicrosoftWindows".

-   `shutdown_command` (string) - The command to use to gracefully shut down
    the machine once all provisioning is complete. By default this is an
    empty string, which tells Packer to just forcefully shut down the
    machine. This setting can be safely omitted if for example, a shutdown
    command to gracefully halt the machine is configured inside a
    provisioning script. If one or more scripts require a reboot it is
    suggested to leave this blank (since reboots may fail) and instead
    specify the final shutdown command in your last script.

-   `shutdown_timeout` (string) - The amount of time to wait after executing
    the `shutdown_command` for the virtual machine to actually shut down.
    If the machine doesn't shut down in this time it is considered an
    error. By default, the time out is "5m" (five minutes).

-   `skip_compaction` (boolean) - If `true` skip compacting the hard disk for
    the virtual machine when exporting. This defaults to `false`.

-   `skip_export` (boolean) - If `true` Packer will skip the export of the VM.
    If you are interested only in the VHD/VHDX files, you can enable this
    option. The resulting VHD/VHDX file will be output to
    `<output_directory>/Virtual Hard Disks`. By default this option is `false`
    and Packer will export the VM to `output_directory`.

-   `switch_name` (string) - The name of the switch to connect the virtual
    machine to. By default, leaving this value unset will cause Packer to
    try and determine the switch to use by looking for an external switch
    that is up and running.

-   `switch_vlan_id` (string) - This is the VLAN of the virtual switch's
    network card. By default none is set. If none is set then a VLAN is not
    set on the switch's network card. If this value is set it should match
    the VLAN specified in by `vlan_id`.

-   `temp_path` (string) - The location under which Packer will create a
    directory to house all the VM files and folders during the build.
    By default `%TEMP%` is used which, for most systems, will evaluate to
    `%USERPROFILE%/AppData/Local/Temp`.

    The build directory housed under `temp_path` will have a name similar
    to `packerhv1234567`. The seven digit number at the end of the name is
    automatically generated by Packer to ensure the directory name is
    unique.

-   `use_fixed_vhd_format` (boolean) - If true, creates the boot disk on the
    virtual machine as a fixed VHD format disk. The default is `false`, which
    creates a dynamic VHDX format disk. This option requires setting
    `generation` to `1`, `skip_compaction` to `true`, and
    `differencing_disk` to `false`. Additionally, any value entered for
    `disk_block_size` will be ignored. The most likely use case for this
    option is outputing a disk that is in the format required for upload to
    Azure.

-   `vlan_id` (string) - This is the VLAN of the virtual machine's network
    card for the new virtual machine. By default none is set. If none is set
    then VLANs are not set on the virtual machine's network card.

-   `vm_name` (string) - This is the name of the new virtual machine,
    without the file extension. By default this is "packer-BUILDNAME",
    where "BUILDNAME" is the name of the build.

## Boot Command

The `boot_command` configuration is very important: it specifies the keys to
type when the virtual machine is first booted in order to start the OS
installer. This command is typed after `boot_wait`, which gives the virtual
machine some time to actually load the ISO.

As documented above, the `boot_command` is an array of strings. The strings
are all typed in sequence. It is an array only to improve readability within
the template.

The boot command is "typed" character for character over the virtual keyboard
to the machine, simulating a human actually typing the keyboard.

<%= partial "partials/builders/boot-command" %>

The example shown below is a working boot command used to start an Ubuntu
12.04 installer:

``` json
[
  "<esc><esc><enter><wait>",
  "/install/vmlinuz noapic ",
  "preseed/url=http://{{ .HTTPIP }}:{{ .HTTPPort }}/preseed.cfg ",
  "debian-installer=en_US auto locale=en_US kbd-chooser/method=us ",
  "hostname={{ .Name }} ",
  "fb=false debconf/frontend=noninteractive ",
  "keyboard-configuration/modelcode=SKIP keyboard-configuration/layout=USA ",
  "keyboard-configuration/variant=USA console-setup/ask_detect=false ",
  "initrd=/install/initrd.gz -- <enter>"
]
```

For more examples of various boot commands, see the sample projects from our
[community templates page](/community-tools.html#templates).

## Integration Services

Packer will automatically attach the integration services ISO as a DVD drive
for the version of Hyper-V that is running.

## Generation 1 vs Generation 2

Floppy drives are no longer supported by generation 2 machines. This requires
you to take another approach when dealing with preseed or answer files. Two
possible options are using virtual DVD drives or using Packers built in web
server.

When dealing with Windows you need to enable UEFI drives for generation 2
virtual machines.

## Creating an ISO From a Directory

Programs like mkisofs can be used to create an ISO from a directory. There is
a [windows version of
mkisofs](http://opensourcepack.blogspot.co.uk/p/cdrtools.html) available.

Below is a working PowerShell script that can be used to create a Windows
answer ISO:

``` powershell
$isoFolder = "answer-iso"
if (test-path $isoFolder){
  remove-item $isoFolder -Force -Recurse
}

if (test-path windows\windows-2012R2-serverdatacenter-amd64\answer.iso){
  remove-item windows\windows-2012R2-serverdatacenter-amd64\answer.iso -Force
}

mkdir $isoFolder

copy windows\windows-2012R2-serverdatacenter-amd64\Autounattend.xml $isoFolder\
copy windows\windows-2012R2-serverdatacenter-amd64\sysprep-unattend.xml $isoFolder\
copy windows\common\set-power-config.ps1 $isoFolder\
copy windows\common\microsoft-updates.ps1 $isoFolder\
copy windows\common\win-updates.ps1 $isoFolder\
copy windows\common\run-sysprep.ps1 $isoFolder\
copy windows\common\run-sysprep.cmd $isoFolder\

$textFile = "$isoFolder\Autounattend.xml"

$c = Get-Content -Encoding UTF8 $textFile

# Enable UEFI and disable Non EUFI
$c | % { $_ -replace '<!-- Start Non UEFI -->','<!-- Start Non UEFI' } | % { $_ -replace '<!-- Finish Non UEFI -->','Finish Non UEFI -->' } | % { $_ -replace '<!-- Start UEFI compatible','<!-- Start UEFI compatible -->' } | % { $_ -replace 'Finish UEFI compatible -->','<!-- Finish UEFI compatible -->' } | sc -Path $textFile

& .\mkisofs.exe -r -iso-level 4 -UDF -o windows\windows-2012R2-serverdatacenter-amd64\answer.iso $isoFolder

if (test-path $isoFolder){
  remove-item $isoFolder -Force -Recurse
}
```
