### 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).
- `clone_all_snapshots` (boolean) - 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.
If `clone_from_vmcx_path` is set, this setting has no effect and any
snapshots associated with the source VM will also be present in the
resultant VM.
If `clone_from_snapshot_name` is configured, this setting has no
effect and the resultant machine will not contain any snapshots.
- `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.
This setting only has an effect if using `clone_from_vm_name` and is
ignored otherwise.
- `copy_in_compare` (boolean) - 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:
`$compatibilityReport = Hyper-V\Compare-VM -Path $VirtualMachinePath -VirtualMachinePath $importPath -SmartPagingFilePath $importPath -SnapshotFilePath $importPath -VhdDestinationPath $VirtualHarddisksPath -GenerateNewId -Copy:$copy`
Where $copy is replaced with either true or false depending on the value of
"copy_in_compare".
- `configuration_version` (string) - This allows you to set the vm version when
calling New-VM to generate the vm.
- `cpus` (number) - The number of CPUs the virtual machine should use. If
this isn't specified, the default is 1 CPU.
- `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.
- `floppy_label` (string) - The label to use for the floppy disk that
is attached when the VM is booted. This is most useful for cloud-init,
Kickstart or other early initialization tools, which can benefit from labelled floppy disks.
By default, the floppy label will be 'packer'.
- `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.
- `keep_registered` (bool) - If "true", Packer will not delete the VM from
The Hyper-V manager.
- `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.
- `memory` (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.
- `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.
