» Hyper-V Builder (from a vmcx)

Type: hyperv-vmcx

The Hyper-V Packer builder is able to use exported virtual machines or clone existing Hyper-V virtual machines.

Typically, the builder imports or clones an existing virtual machine, boots it, provisions software within the OS, and then shuts it down. The result of the Hyper-V builder is a directory containing all the files necessary to run the virtual machine portably.

» Basic Examples

Here are some basic examples. Neither example would really do anything more than producing a copy of the source virtual machine. However, the examples could be used as a starting point for more advanced templates.

Import from folder:

{
  "type": "hyperv-vmcx",
  "clone_from_vmcx_path": "c:/path/to/ubuntu-12.04.5-server-amd64",
  "ssh_username": "packer",
  "ssh_password": "packer",
  "shutdown_command": "echo 'packer' | sudo -S shutdown -P now"
}

Clone from existing virtual machine:

{
    "clone_from_vm_name": "ubuntu-12.04.5-server-amd64",
    "shutdown_command": "echo 'packer' | sudo -S shutdown -P now",
    "ssh_password": "packer",
    "ssh_username": "packer",
    "type": "hyperv-vmcx"
}

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 can be configured for this builder.

» ISO Configuration Reference

By default, Packer will symlink, download or copy image files to the Packer cache into a "hash($iso_url+$iso_checksum).$iso_target_extension" file. Packer uses hashicorp/go-getter in file mode in order to perform a download.

go-getter supports the following protocols:

  • Local files
  • Git
  • Mercurial
  • HTTP
  • Amazon S3

Examples: go-getter can guess the checksum type based on iso_checksum len.

{ "iso_checksum": "946a6077af6f5f95a51f82fdc44051c7aa19f9cfc5f737954845a6050543d7c2", "iso_url": "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso" }

{
"iso_checksum_type": "file",
"iso_checksum": "ubuntu.org/..../ubuntu-14.04.1-server-amd64.iso.sum",
"iso_url": "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"
}
{
"iso_checksum_url": "./shasums.txt",
"iso_url": "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"
}
{
"iso_checksum_type": "sha256",
"iso_checksum_url": "./shasums.txt",
"iso_url": "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"
}

» Required:

  • iso_checksum (string) - The checksum for the ISO file or virtual hard drive file. The algorithm to use when computing the checksum can be optionally specified with iso_checksum_type. When iso_checksum_type is not set packer will guess the checksumming type based on iso_checksum length. iso_checksum can be also be a file or an URL, in which case iso_checksum_type must be set to file; the go-getter will download it and use the first hash found.

  • iso_url (string) - A URL to the ISO containing the installation image or virtual hard drive (VHD or VHDX) file to clone.

» Optional:

  • iso_checksum_url (string) - An URL to a checksum file containing a checksum for the ISO file. At least one of iso_checksum and iso_checksum_url must be defined. iso_checksum_url will be ignored if iso_checksum is non empty.

  • 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", "sha512" or "file". 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_checksum_type must be set to file when iso_checksum is an url.

  • iso_urls ([]string) - 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_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 and checksum as its name.

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

» Required for virtual machine import:

  • clone_from_vmcx_path (string) - The path to a directory containing a previously exported virtual machine. The exported machine will be used as the source for new VM.

    note: You should provide the named directory that contains the "Virtual Machines", "Snapshots", and/or "Virtual Hard Disks" subdirectories, not the .vmcx file itself.

» Required for virtual machine clone:

  • clone_from_vm_name (string) - The name of the VM to clone from. Ideally the machine to clone from should be shutdown.

» Optional:

  • clone_from_vmcx_path (string) - This is the path to a directory containing an exported virtual machine.

  • clone_from_vm_name (string) - This is the name of the virtual machine to clone from.

  • clone_from_snapshot_name (string) - The name of a snapshot in the source machine to use as a starting point for the clone. If the value given is an empty string, the last snapshot present in the source will be chosen as the starting point for the new VM.

  • clone_all_snapshots (bool) - If set to true all snapshots present in the source machine will be copied when the machine is cloned. The final result of the build will be an exported virtual machine that contains all the snapshots of the parent.

  • differencing_disk (bool) - 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.

  • copy_in_compare (bool) - When cloning a vm to build from, we run a powershell Compare-VM command, which, depending on your version of Windows, may need the "Copy" flag to be set to true or false. Defaults to "false". Command:

  • disk_block_size (uint) - 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.

  • memory (uint) - The amount, in megabytes, of RAM to assign to the VM. By default, this is 1 GB.

  • secondary_iso_images ([]string) - 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.

  • disk_additional_size ([]uint) - 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.

  • 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.

  • 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.

  • 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.

  • 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".

  • 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.

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

  • generation (uint) - 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.

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

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

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

  • 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".

  • enable_virtualization_extensions (bool) - 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.

  • 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.

  • configuration_version (string) - This allows you to set the vm version when calling New-VM to generate the vm.

  • keep_registered (bool) - If "true", Packer will not delete the VM from The Hyper-V manager.

  • communicator (string) - Communicator

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

  • skip_export (bool) - 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 /Virtual Hard Disks. By default this option is false and Packer will export the VM to output_directory.

  • headless (bool) - 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.

» 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> <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.

  • <menu> - Simulates pressing the Menu key.

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

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

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

  • <leftSuper> <rightSuper> - Simulates pressing the ⌘ or Windows 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.

  • <waitXX> - Add an arbitrary pause before sending any additional keys. The format of XX is a sequence of positive decimal numbers, each with optional fraction and a unit suffix, such as 300ms, 1.5h or 2h45m. Valid time units are ns, us (or µs), ms, s, m, h. For example <wait10m> or <wait1m20s>

» On/Off variants

Any printable keyboard character, and of these "special" expressions, with the exception of the <wait> types, can also be toggled on or off. For example, to simulate ctrl+c, use <leftCtrlOn>c<leftCtrlOff>. Be sure to release them, otherwise they will be held down until the machine reboots.

To hold the c key down, you would use <cOn>. Likewise, <cOff> to release.

» Templates inside boot command

In addition to the special keys, each command to type is treated as a template engine. 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!
  • Name - The name of the VM.

For more examples of various boot commands, see the sample projects from our community templates page.

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

[
  "<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.

» 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 available.

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

$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
}
