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: ```json { "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: ```json { "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](/docs/templates/legacy_json_templates/communicator) can be configured for this builder. ## ISO Configuration Reference @include 'packer-plugin-sdk/multistep/commonsteps/ISOConfig.mdx' ### Required: @include 'packer-plugin-sdk/multistep/commonsteps/ISOConfig-required.mdx' ### Optional: @include 'packer-plugin-sdk/multistep/commonsteps/ISOConfig-not-required.mdx' ### 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: @include 'builder/hyperv/vmcx/Config-not-required.mdx' @include 'builder/hyperv/common/CommonConfig-not-required.mdx' ## Communicator configuration reference ### Optional common fields: @include 'packer-plugin-sdk/communicator/Config-not-required.mdx' ### Optional SSH fields: @include 'packer-plugin-sdk/communicator/SSH-not-required.mdx' @include 'packer-plugin-sdk/communicator/SSH-Private-Key-File-not-required.mdx' ### Optional WinRM fields: @include 'packer-plugin-sdk/communicator/WinRM-not-required.mdx' ### CD configuration @include 'packer-plugin-sdk/multistep/commonsteps/CDConfig.mdx' #### Optional: @include 'packer-plugin-sdk/multistep/commonsteps/CDConfig-not-required.mdx' ## 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. @include 'builders/boot-command.mdx' The example shown below is a working boot command used to start an Ubuntu 12.04 installer: ```json [ "", "/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 -- " ] ``` For more examples of various boot commands, see the sample projects from our [community templates page](/community-tools#templates). ## Http directory configuration @include 'packer-plugin-sdk/multistep/commonsteps/HTTPConfig.mdx' ### Optional: @include 'packer-plugin-sdk/multistep/commonsteps/HTTPConfig-not-required.mdx' ## 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 the `cd_files` option or using Packer's 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 '','','Finish Non UEFI -->' } | % { $_ -replace '' } | % { $_ -replace '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 } ``` ## Example For Windows Server 2012 R2 Generation 2 Packer config: ```json { "builders": [ { "vm_name": "windows2012r2", "type": "hyperv-iso",

you'll probably want to turn it off or restrict its permissions as part of a shutdown script at the end of Packer's provisioning process.
