Proxmox Clone

Type: proxmox-clone Artifact BuilderId: proxmox.clone

The proxmox-clone Packer builder is able to create new images for use with Proxmox. The builder takes a virtual machine template, runs any provisioning necessary on the image after launching it, then creates a virtual machine template. This template can then be used as to create new virtual machines within Proxmox.

Disks specified in a proxmox-clone builder configuration will replace disks that are already present on the cloned VM template. If you want to reuse the disks of the cloned VM, don't specify disks in your configuration.

The builder does not manage templates. Once it creates a template, it is up to you to use it or delete it.

Configuration Reference

There are many configuration options available for the builder. They are segmented below into two categories: required and optional parameters. Within each category, the available configuration keys are alphabetized.

You may also want to take look at the general configuration references for VirtIO RNG device and PCI Devices configuration references, which can be found further down the page.

In addition to the options listed here, a communicator can be configured for this builder.

If no communicator is defined, an SSH key is generated for use, and is used in the image's Cloud-Init settings for provisioning.

Required:

  • clone_vm (string) - The name of the VM Packer should clone and build from. Either clone_vm or clone_vm_id must be specifed.

  • clone_vm_id (int) - The ID of the VM Packer should clone and build from. Proxmox VMIDs are limited to the range 100-999999999. Either clone_vm or clone_vm_id must be specifed.

An iso (CD) containing custom files can be made available for your build.

By default, no extra CD will be attached. All files listed in this setting get placed into the root directory of the CD and the CD is attached as the second CD device.

This config exists to work around modern operating systems that have no way to mount floppy disks, which was our previous go-to for adding files at boot time.

  • cd_files ([]string) - A list of files to place onto a CD that is attached when the VM is booted. This can include either files or directories; any directories will be copied onto the CD recursively, preserving directory structure hierarchy. Symlinks will have the link's target copied into the directory tree on the CD where the symlink was. File globbing is allowed.

    Usage example (JSON):

    "cd_files": ["./somedirectory/meta-data", "./somedirectory/user-data"],
"cd_label": "cidata",

    Usage example (HCL):

    cd_files = ["./somedirectory/meta-data", "./somedirectory/user-data"]
cd_label = "cidata"

    The above will create a CD with two files, user-data and meta-data in the CD root. This specific example is how you would create a CD that can be used for an Ubuntu 20.04 autoinstall.

    Since globbing is also supported,

    cd_files = ["./somedirectory/*"]
cd_label = "cidata"

    Would also be an acceptable way to define the above cd. The difference between providing the directory with or without the glob is whether the directory itself or its contents will be at the CD root.

    Use of this option assumes that you have a command line tool installed that can handle the iso creation. Packer will use one of the following tools:

    • xorriso
    • mkisofs
    • hdiutil (normally found in macOS)
    • oscdimg (normally found in Windows as part of the Windows ADK)

  • cd_content (map[string]string) - Key/Values to add to the CD. The keys represent the paths, and the values contents. It can be used alongside cd_files, which is useful to add large files without loading them into memory. If any paths are specified by both, the contents in cd_content will take precedence.

    Usage example (HCL):

    cd_files = ["vendor-data"]
cd_content = {
  "meta-data" = jsonencode(local.instance_data)
  "user-data" = templatefile("user-data", { packages = ["nginx"] })
}
cd_label = "cidata"

  • cd_label (string) - CD Label

  • insecure_skip_tls_verify (bool) - Skip validating the certificate.

  • username (string) - Username when authenticating to Proxmox, including the realm. For example user@pve to use the local Proxmox realm. When using token authentication, the username must include the token id after an exclamation mark. For example, user@pve!tokenid. Can also be set via the PROXMOX_USERNAME environment variable.

  • password (string) - Password for the user. For API tokens please use token. Can also be set via the PROXMOX_PASSWORD environment variable. Either password or token must be specifed. If both are set, token takes precedence.

  • token (string) - Token for authenticating API calls. This allows the API client to work with API tokens instead of user passwords. Can also be set via the PROXMOX_TOKEN environment variable. Either password or token must be specifed. If both are set, token takes precedence.

  • node (string) - Which node in the Proxmox cluster to start the virtual machine on during creation.

  • pool (string) - Name of resource pool to create virtual machine in.

  • task_timeout (duration string | ex: "1h5m2s") - task_timeout (duration string | ex: "10m") - The timeout for Promox API operations, e.g. clones. Defaults to 1 minute.

  • packet_queues (int) - Number of packet queues to be used on the device. Values greater than 1 indicate that the multiqueue feature is activated. For best performance, set this to the number of cores available to the virtual machine. CPU load on the host and guest systems will increase as the traffic increases, so activate this option only when the VM has to handle a great number of incoming connections, such as when the VM is operating as a router, reverse proxy or a busy HTTP server. Requires virtio network adapter. Defaults to 0.

  • mac_address (string) - Give the adapter a specific MAC address. If not set, defaults to a random MAC. If value is "repeatable", value of MAC address is deterministic based on VM ID and NIC ID.

]

Optional:

  • type (string) - The type of disk. Can be scsi, sata, virtio or ide. Defaults to scsi.

  • storage_pool (string) - Required. Name of the Proxmox storage pool to store the virtual machine disk on. A local-lvm pool is allocated by the installer, for example.

  • storage_pool_type (string) - This option is deprecated.

  • disk_size (string) - The size of the disk, including a unit suffix, such as 10G to indicate 10 gigabytes.

  • cache_mode (string) - How to cache operations to the disk. Can be none, writethrough, writeback, unsafe or directsync. Defaults to none.

  • format (string) - The format of the file backing the disk. Can be raw, cow, qcow, qed, qcow2, vmdk or cloop. Defaults to raw.

  • io_thread (bool) - Create one I/O thread per storage controller, rather than a single thread for all I/O. This can increase performance when multiple disks are used. Requires virtio-scsi-single controller and a scsi or virtio disk. Defaults to false.

    This cannot work with virtio disks.

CloudInit Ip Configuration

If you have configured more than one network interface, make sure to match the order of network_adapters and ipconfig.

Usage example (JSON):

[

    {
      "ip": "192.168.1.55/24",
      "gateway": "192.168.1.1",
      "ip6": "fda8:a260:6eda:20::4da/128",
      "gateway6": "fda8:a260:6eda:20::1"
    }

]

  • ip (string) - Either an IPv4 address (CIDR notation) or dhcp.

  • gateway (string) - IPv4 gateway.

  • ip6 (string) - Can be an IPv6 address (CIDR notation), auto (enables SLAAC), or dhcp.

  • gateway6 (string) - IPv6 gateway.

ISO Files

ISO files attached to the virtual machine.

JSON Example:


    "additional_iso_files": [
        {
              "type": "scsi",
              "iso_file": "local:iso/virtio-win-0.1.185.iso",
              "unmount": true,
              "iso_checksum": "af2b3cc9fa7905dea5e58d31508d75bba717c2b0d5553962658a47aebc9cc386"
        }
     ]

HCL2 example:


    additional_iso_files {
      type = "scsi"
      iso_file = "local:iso/virtio-win-0.1.185.iso"
      unmount = true
      iso_checksum = "af2b3cc9fa7905dea5e58d31508d75bba717c2b0d5553962658a47aebc9cc386"
    }

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 length, and it is also possible to specify the checksum type.

In JSON:


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



    "iso_checksum": "file:ubuntu.org/..../ubuntu-14.04.1-server-amd64.iso.sum",
    "iso_url": "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"



    "iso_checksum": "file://./shasums.txt",
    "iso_url": "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"



    "iso_checksum": "file:./shasums.txt",
    "iso_url": "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"

In HCL2:


    iso_checksum = "946a6077af6f5f95a51f82fdc44051c7aa19f9cfc5f737954845a6050543d7c2"
    iso_url = "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"



    iso_checksum = "file:ubuntu.org/..../ubuntu-14.04.1-server-amd64.iso.sum"
    iso_url = "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"



    iso_checksum = "file://./shasums.txt"
    iso_url = "ubuntu.org/.../ubuntu-14.04.1-server-amd64.iso"



    iso_checksum = "file:./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 type of the checksum is specified within the checksum field as a prefix, ex: "md5:{$checksum}". The type of the checksum can also be omitted and Packer will try to infer it based on string length. Valid values are "none", "{$checksum}", "md5:{$checksum}", "sha1:{$checksum}", "sha256:{$checksum}", "sha512:{$checksum}" or "file:{$path}". Here is a list of valid checksum values:

    • md5:090992ba9fd140077b0661cb75f7ce13
    • 090992ba9fd140077b0661cb75f7ce13
    • sha1:ebfb681885ddf1234c18094a45bbeafd91467911
    • ebfb681885ddf1234c18094a45bbeafd91467911
    • sha256:ed363350696a726b7932db864dda019bd2017365c9e299627830f06954643f93
    • ed363350696a726b7932db864dda019bd2017365c9e299627830f06954643f93
    • file:http://releases.ubuntu.com/20.04/SHA256SUMS
    • file:file://./local/path/file.sum
    • file:./local/path/file.sum
    • none Although the checksum will not be verified when it is set to "none", this is not recommended since these files can be very large and corruption does happen from time to time.

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

Optional

  • 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.

  • device (string) - DEPRECATED. Assign bus type with type. Optionally assign a bus index with index. Bus type and bus index that the ISO will be mounted on. Can be ideX, sataX or scsiX. For ide the bus index ranges from 0 to 3, for sata from 0 to 5 and for scsi from 0 to 30. Defaulted to ide3 in versions up to v1.8, now defaults to dynamic ide assignment (next available ide bus index after hard disks are allocated)

  • type (string) - Bus type that the ISO will be mounted on. Can be ide, sata or scsi. Defaults to ide.

  • index (string) - Optional: Used in combination with type to statically assign an ISO to a bus index.

  • iso_file (string) - Path to the ISO file to boot from, expressed as a proxmox datastore path, for example local:iso/Fedora-Server-dvd-x86_64-29-1.2.iso. Either iso_file OR iso_url must be specifed.

  • iso_storage_pool (string) - Proxmox storage pool onto which to upload the ISO file.

  • iso_download_pve (bool) - Download the ISO directly from the PVE node rather than through Packer.

    Defaults to false

  • unmount (bool) - If true, remove the mounted ISO from the template after finishing. Defaults to false.

  • keep_cdrom_device (bool) - Keep CDRom device attached to template if unmounting ISO. Defaults to false. Has no effect if unmount is false

An iso (CD) containing custom files can be made available for your build.

By default, no extra CD will be attached. All files listed in this setting get placed into the root directory of the CD and the CD is attached as the second CD device.

This config exists to work around modern operating systems that have no way to mount floppy disks, which was our previous go-to for adding files at boot time.

  • cd_files ([]string) - A list of files to place onto a CD that is attached when the VM is booted. This can include either files or directories; any directories will be copied onto the CD recursively, preserving directory structure hierarchy. Symlinks will have the link's target copied into the directory tree on the CD where the symlink was. File globbing is allowed.

    Usage example (JSON):

    "cd_files": ["./somedirectory/meta-data", "./somedirectory/user-data"],
"cd_label": "cidata",

    Usage example (HCL):

    cd_files = ["./somedirectory/meta-data", "./somedirectory/user-data"]
cd_label = "cidata"

    The above will create a CD with two files, user-data and meta-data in the CD root. This specific example is how you would create a CD that can be used for an Ubuntu 20.04 autoinstall.

    Since globbing is also supported,

    cd_files = ["./somedirectory/*"]
cd_label = "cidata"

    Would also be an acceptable way to define the above cd. The difference between providing the directory with or without the glob is whether the directory itself or its contents will be at the CD root.

    Use of this option assumes that you have a command line tool installed that can handle the iso creation. Packer will use one of the following tools:

    • xorriso
    • mkisofs
    • hdiutil (normally found in macOS)
    • oscdimg (normally found in Windows as part of the Windows ADK)

  • cd_content (map[string]string) - Key/Values to add to the CD. The keys represent the paths, and the values contents. It can be used alongside cd_files, which is useful to add large files without loading them into memory. If any paths are specified by both, the contents in cd_content will take precedence.

    Usage example (HCL):

    cd_files = ["vendor-data"]
cd_content = {
  "meta-data" = jsonencode(local.instance_data)
  "user-data" = templatefile("user-data", { packages = ["nginx"] })
}
cd_label = "cidata"

  • cd_label (string) - CD Label

EFI Config

Set the efidisk storage options. This needs to be set if you use ovmf uefi boot (supersedes the efidisk option).

Usage example (JSON):


    {
      "efi_storage_pool": "local",
      "pre_enrolled_keys": true,
      "efi_format": "raw",
      "efi_type": "4m"
    }

Optional:

  • efi_storage_pool (string) - Name of the Proxmox storage pool to store the EFI disk on.

  • efi_format (string) - The format of the file backing the disk. Can be raw, cow, qcow, qed, qcow2, vmdk or cloop. Defaults to raw.

  • pre_enrolled_keys (bool) - Whether Microsoft Standard Secure Boot keys should be pre-loaded on the EFI disk. Defaults to false.

  • efi_type (string) - Specifies the version of the OVMF firmware to be used. Can be 2m or 4m. Defaults to 4m.

VirtIO RNG device

  • rng0 (object): Configure Random Number Generator via VirtIO. A virtual hardware-RNG can be used to provide entropy from the host system to a guest VM helping avoid entropy starvation which might cause the guest system slow down. The device is sourced from a host device and guest, his use can be limited: max_bytes bytes of data will become available on a period ms timer. PVE documentation recommends to always use a limiter to avoid guests using too many host resources.

HCL2 example:


    rng0 {
      source    = "/dev/urandom"
      max_bytes = 1024
      period    = 1000
    }

JSON example:


    {
        "rng0": {
            "source": "/dev/urandom",
            "max_bytes": 1024,
            "period": 1000
        }
    }

Required:

  • source (string) - Device on the host to gather entropy from. /dev/urandom should be preferred over /dev/random as Proxmox PVE documentation suggests. /dev/hwrng can be used to pass through a hardware RNG. Can be one of /dev/urandom, /dev/random, /dev/hwrng.

  • max_bytes (int) - Maximum bytes of entropy allowed to get injected into the guest every period milliseconds. Use a lower value when using /dev/random since can lead to entropy starvation on the host system. 0 disables limiting and according to PVE documentation is potentially dangerous for the host. Recommended value: 1024.

Optional:

  • period (int) - Period in milliseconds on which the the entropy-injection quota is reset. Can be a positive value. Recommended value: 1000.

PCI devices

Allows passing through a host PCI device into the VM. For example, a graphics card or a network adapter. Devices that are mapped into a guest VM are no longer available on the host. A minimal configuration only requires either the host or the mapping key to be specifed.

Note: VMs with passed-through devices cannot be migrated.

HCL2 example:


    pci_devices {
      host          = "0000:0d:00.1"
      pcie          = false
      device_id     = "1003"
      legacy_igd    = false
      mdev          = "some-model"

    }

Optional:

  • host (string) - The PCI ID of a host’s PCI device or a PCI virtual function. You can us the lspci command to list existing PCI devices. Either this or the mapping key must be set.

  • device_id (string) - Override PCI device ID visible to guest.

  • legacy_igd (bool) - Pass this device in legacy IGD mode, making it the primary and exclusive graphics device in the VM. Requires pc-i440fx machine type and VGA set to none. Defaults to false.

  • mapping (string) - The ID of a cluster wide mapping. Either this or the host key must be set.

  • pcie (bool) - Present the device as a PCIe device (needs q35 machine model). Defaults to false.

  • mdev (string) - The type of mediated device to use. An instance of this type will be created on startup of the VM and will be cleaned up when the VM stops.

  • hide_rombar (bool) - Specify whether or not the device’s ROM BAR will be visible in the guest’s memory map. Defaults to false.

  • romfile (string) - Custom PCI device rom filename (must be located in /usr/share/kvm/).

  • sub_device_id (string) - Override PCI subsystem device ID visible to guest.

  • sub_vendor_id (string) - Override PCI subsystem vendor ID visible to guest.

  • vendor_id (string) - Override PCI vendor ID visible to guest.

  • x_vga (bool) - Enable vfio-vga device support. Defaults to false.

Example: Cloud-Init enabled Debian

Here is a basic example creating a Debian 10 server image. This assumes that there exists a Cloud-Init enabled image on the Proxmox server named debian-10-4.
