The builder takes an ISO image, 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. 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. In addition to the options listed here, a [communicator](/docs/templates/communicator) can be configured for this builder. ### Required: - `proxmox_url` (string) - URL to the Proxmox API, including the full path, so `https://:/api2/json` for example. Can also be set via the `PROXMOX_URL` environment variable. - `username` (string) - Username when authenticating to Proxmox, including the realm. For example `user@pve` to use the local Proxmox realm. Can also be set via the `PROXMOX_USERNAME` environment variable. - `password` (string) - Password for the user. Can also be set via the `PROXMOX_PASSWORD` environment variable. - `node` (string) - Which node in the Proxmox cluster to start the virtual machine on during creation. - `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_url` (string) - URL to an ISO file to upload to Proxmox, and then boot from. Either `iso_file` OR `iso_url` must be specifed. - `iso_storage_pool` (string) - Proxmox storage pool onto which to upload the ISO file. - `iso_checksum` (string) - Checksum of the ISO file. - `iso_checksum_type` (string) - Type of the checksum. Can be md5, sha1, sha256, sha512 or none. Corruption of large files, such as ISOs, can occur during transfer from time to time. As such, setting this to none is not recommended. ### Optional: - `insecure_skip_tls_verify` (bool) - Skip validating the certificate. - `pool` (string) - Name of resource pool to create virtual machine in. - `vm_name` (string) - Name of the virtual machine during creation. If not given, a random uuid will be used. - `vm_id` (int) - The ID used to reference the virtual machine. This will also be the ID of the final template. If not given, the next free ID on the node will be used. - `memory` (int) - How much memory, in megabytes, to give the virtual machine. Defaults to `512`. - `cores` (int) - How many CPU cores to give the virtual machine. Defaults to `1`. - `sockets` (int) - How many CPU sockets to give the virtual machine. Defaults to `1` - `cpu_type` (string) - The CPU type to emulate. See the Proxmox API documentation for the complete list of accepted values. For best performance, set this to `host`. Defaults to `kvm64`. - `os` (string) - The operating system. Can be `wxp`, `w2k`, `w2k3`, `w2k8`, `wvista`, `win7`, `win8`, `win10`, `l24` (Linux 2.4), `l26` (Linux 2.6+), `solaris` or `other`. Defaults to `other`. - `vga` (object) - The graphics adapter to use. Example: ```json { "type": "vmware", "memory": 32 } ``` - `type` (string) - Can be `cirrus`, `none`, `qxl`,`qxl2`, `qxl3`, `qxl4`, `serial0`, `serial1`, `serial2`, `serial3`, `std`, `virtio`, `vmware`. Defaults to `std`. - `memory` (int) - How much memory to assign. - `network_adapters` (array of objects) - Network adapters attached to the virtual machine. Example: ```json [ { "model": "virtio", "bridge": "vmbr0", "vlan_tag": "10", "firewall": true } ] ``` - `bridge` (string) - Required. Which Proxmox bridge to attach the adapter to. - `model` (string) - Model of the virtual network adapter. Can be `rtl8139`, `ne2k_pci`, `e1000`, `pcnet`, `virtio`, `ne2k_isa`, `i82551`, `i82557b`, `i82559er`, `vmxnet3`, `e1000-82540em`, `e1000-82544gc` or `e1000-82545em`. Defaults to `e1000`. - `mac_address` (string) - Give the adapter a specific MAC address. If not set, defaults to a random MAC. - `vlan_tag` (string) - If the adapter should tag packets. Defaults to no tagging. - `firewall` (bool) - If the interface should be protected by the firewall. Defaults to `false`. - `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 set this option only when the VM has to handle a great number of incoming connections, such as when the VM is running as a router, reverse proxy or a busy HTTP server. Requires `virtio` network adapter. Defaults to `0`. - `disks` (array of objects) - Disks attached to the virtual machine. Example: ```json [ { "type": "scsi", "disk_size": "5G", "storage_pool": "local-lvm", "storage_pool_type": "lvm" } ] ``` - `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) - Required. The type of the pool, can be `lvm`, `lvm-thin`, `zfspool`, `cephfs`, `rbd` or `directory`. - `type` (string) - The type of disk. Can be `scsi`, `sata`, `virtio` or `ide`.

Defaults to `false`. - `onboot` (boolean) - Specifies whether a VM will be started during system bootup. Defaults to `false`. - `qemu_agent` (boolean) - Disables QEMU Agent option for this VM. When enabled, then `qemu-guest-agent` must be installed on the guest. When disabled, then `ssh_host` should be used. Defaults to `true`. - `scsi_controller` (string) - The SCSI controller model to emulate. Can be `lsi`, `lsi53c810`, `virtio-scsi-pci`, `virtio-scsi-single`, `megasas`, or `pvscsi`. Defaults to `lsi`. - `cloud_init` (bool) - If true, add a Cloud-Init CDROM drive after the virtual machine has been converted to a template. - `cloud_init_storage_pool` - (string) - Name of the Proxmox storage pool to store the Cloud-Init CDROM on.

Note that the iso file needs to be manually downloaded. ```json { "variables": { "username": "apiuser@pve", "password": "supersecret" }, "builders": [ { "type": "proxmox", "proxmox_url": "https://my-proxmox.my-domain:8006/api2/json", "insecure_skip_tls_verify": true, "username": "{{user `username`}}", "password": "{{user `password`}}", "node": "my-proxmox", "network_adapters": [ { "bridge": "vmbr0" } ], "disks": [ { "type": "scsi", "disk_size": "5G", "storage_pool": "local-lvm", "storage_pool_type": "lvm" } ], "iso_file": "local:iso/Fedora-Server-dvd-x86_64-29-1.2.iso", "http_directory": "config", "boot_wait": "10s", "boot_command": [ " ip=dhcp inst.cmdline inst.ks=http://{{.HTTPIP}}:{{.HTTPPort}}/ks.cfg" ], "ssh_username": "root", "ssh_timeout": "15m", "ssh_password": "packer", "unmount_iso": true, "template_name": "fedora-29", "template_description": "Fedora 29-1.2, generated on {{ isotime \"2006-01-02T15:04:05Z\" }}" } ] } ```
