# 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, booting it, installing an OS, provisioning software within
the OS, then shutting it 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"
}
```

It is important to add a `shutdown_command`. By default Packer halts the
virtual machine and the file system may not be sync'd. Thus, changes made in a
provisioner might not be saved.

## 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 OS ISO file or virtual
    harddrive file. Because these files are so large, this is required and
    Packer will verify it prior to booting a virtual machine with the ISO or
    virtual harddrive attached. The type of the checksum is specified with
    `iso_checksum_type`, documented below.

-   `iso_checksum_type` (string) - The type of the checksum specified in
    `iso_checksum`. Valid values are "none", "md5", "sha1", "sha256", or
    "sha512" currently. While "none" will skip checksumming, this is not
    recommended since ISO files and virtual harddrive files are generally large
    and corruption does happen from time to time.

-   `iso_url` (string) - A URL to the ISO containing the installation image or
    virtual harddrive 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 of this should be
    a duration. Examples are "5s" and "1m30s" which will cause Packer to wait
    five seconds and one minute 30 seconds, respectively. If this isn't specified,
    the default is 10 seconds.

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

-   `disk_additional_size` (array of integers) - The size(s) 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, not fixed-size virtual hard disks,
    so the actual file representing the disk will not use the full size unless it is full.

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

-   `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.

-   `skip_export` (boolean) - If true skips VM export. If you are interested only in the vhd/vhdx files, you can enable this option. This will create
    inline disks which improves the build performance. There will not be any copying of source vhds to temp directory. This defaults to false.
    
-   `enable_dynamic_memory` (boolean) - If true enable dynamic memory for virtual machine.
    This defaults to false.

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

-   `enable_secure_boot` (boolean) - If true enable secure boot for virtual machine.
    This defaults to false.

-   `enable_virtualization_extensions` (boolean) - If true enable virtualization extensions for 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 for virtual machine.

-   `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.

-   `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`.

-   `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) - How should guest additions be installed.
    If value `attach` then attach iso image with by specified by `guest_additions_path`.
    Otherwise guest additions is not installed.

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

-   `http_directory` (string) - Path to a directory to serve using an HTTP
    server. The files in this directory will be available over HTTP that will
    be requestable from the virtual machine. This is useful for hosting
    kickstart files and so on. By default this is "", which means no HTTP
    server will be 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`.
    Because Packer often runs in parallel, Packer will choose a randomly available
    port in this range to run the HTTP server. If you want to force the HTTP
    server to be on one port, make this minimum and maximum port the same.
    By default the values are 8000 and 9000, respectively.

-   `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.

-   `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 will go in the packer cache, with a hash of the
    original filename as its name.

-   `output_directory` (string) - This is the path to the directory where the
    resulting virtual machine will be created. This may be relative or absolute.
    If relative, the path is relative to the working directory when `packer`
    is executed. This directory must not exist or 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 size, in megabytes, of the ram to create
    for the VM. By default, this is 1 GB.

-   `secondary_iso_images` (array of strings) - A list of iso paths to attached 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.

-   `shutdown_command` (string) - The command to use to gracefully shut down the machine once all
    the provisioning is done. By default this is an empty string, which tells Packer to just
    forcefully shut down the machine unless a shutdown command takes place inside script so this may
    safely be omitted. If one or more scripts require a reboot it is suggested to leave this blank
    since reboots may fail and 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 it doesn't shut down in this time, it is an error. By default, the timeout
    is "5m", or five minutes.

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

-   `switch_name` (string) - The name of the switch to connect the virtual machine to. Be defaulting
    this to an empty string, Packer will try to determine the switch to use by looking for
    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`.

-   `vhd_temp_path` (string) - A separate path to be used for storing the VM's
    disk image. The purpose is to enable reading and writing to take place on
    different physical disks (read from VHD temp path, write to regular temp
    path while exporting the VM) to eliminate a single-disk bottleneck.

-   `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.

-   `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".

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

-   `temp_path` (string) - This is the temporary path in which Packer will create the virtual
    machine. Default value is system `%temp%`

## 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. There are
a set of special keys available. If these are in your boot command, they
will be replaced by the proper key:

-   `<bs>` - Backspace

-   `<del>` - Delete

-   `<enter>` and `<return>` - Simulates an actual "enter" or "return" keypress.

-   `<esc>` - Simulates pressing the escape key.

-   `<tab>` - Simulates pressing the tab key.

-   `<f1>` - `<f12>` - Simulates pressing a function key.

-   `<up>` `<down>` `<left>` `<right>` - Simulates pressing an arrow key.

-   `<spacebar>` - Simulates pressing the spacebar.

-   `<insert>` - Simulates pressing the insert key.

-   `<home>` `<end>` - Simulates pressing the home and end keys.

-   `<pageUp>` `<pageDown>` - Simulates pressing the page up and page down keys.

-   `<leftAlt>` `<rightAlt>` - Simulates pressing the alt key.

-   `<leftCtrl>` `<rightCtrl>` - Simulates pressing the ctrl key.

-   `<leftShift>` `<rightShift>` - Simulates pressing the shift key.

-   `<leftAltOn>` `<rightAltOn>` - Simulates pressing and holding the alt key.

-   `<leftCtrlOn>` `<rightCtrlOn>` - Simulates pressing and holding the ctrl key.

-   `<leftShiftOn>` `<rightShiftOn>` - Simulates pressing and holding the shift key.

-   `<leftAltOff>` `<rightAltOff>` - Simulates releasing a held alt key.

-   `<leftCtrlOff>` `<rightCtrlOff>` - Simulates releasing a held ctrl key.

-   `<leftShiftOff>` `<rightShiftOff>` - Simulates releasing a held shift key.

-   `<wait>` `<wait5>` `<wait10>` - Adds a 1, 5 or 10 second pause before
    sending any additional keys. This is useful if you have to generally wait
    for the UI to update before typing more.

When using modifier keys `ctrl`, `alt`, `shift` ensure that you release them,
otherwise they will be held down until the machine reboots. Use lowercase
characters as well inside modifiers. For example: to simulate ctrl+c use
`<leftCtrlOn>c<leftCtrlOff>`.

In addition to the special keys, each command to type is treated as a
[template engine](/docs/templates/engine.html).
The available variables are:

-   `HTTPIP` and `HTTPPort` - The IP and port, respectively of an HTTP server
    that is started serving the directory specified by the `http_directory`
    configuration parameter. If `http_directory` isn't specified, these will
    be blank!

Example boot command. This is actually 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 the built in web server.

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

## Creating iso from 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).

Example powershell script. This is an actually working powershell script 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
}
```
