Packer Builder for VMware vSphere
Type: vsphere-iso
Artifact BuilderId: jetbrains.vsphere
This builder uses the vSphere API, and creates virtual machines remotely. It starts from an ISO file and creates new VMs from scratch.
- VMware Player is not required.
- It uses the official vCenter Server API, and does not require ESXi host modification
- The builder supports versions following the VMware Product Lifecycle Matrix from General Availability to End of General Support. Builds on versions that are end of support may work, but configuration options may throw errors if they do not exist in the vSphere API for those versions.
Examples
See complete Ubuntu, Windows, and macOS templates in the examples folder.
Configuration Reference
There are many configuration options available for this builder. In addition to the items listed here, you will want to look at the general configuration references for HTTP, Floppy, Boot, Hardware, Output, Run, Shutdown, Communicator, Export, configuration references, which are necessary for this build to succeed and can be found further down the page.
create_snapshot
(bool) - Create a snapshot when set totrue
, so the VM can be used as a base for linked clones. Defaults tofalse
.snapshot_name
(string) - Whencreate_snapshot
istrue
,snapshot_name
determines the name of the snapshot. Defaults toCreated By Packer
.convert_to_template
(bool) - Convert VM to a template. Defaults tofalse
.export
(*common.ExportConfig) - Configuration for exporting VM to an ovf file. The VM will not be exported if no Export Configuration is specified.content_library_destination
(*common.ContentLibraryDestinationConfig) - Configuration for importing the VM template to a Content Library. The VM template will not be imported if no Content Library Import Configuration is specified. The import doesn't work if convert_to_template is set to true.
Boot Configuration
The boot configuration is very important: boot_command
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 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.
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 ofXX
is a sequence of positive decimal numbers, each with optional fraction and a unit suffix, such as300ms
,1.5h
or2h45m
. Valid time units arens
,us
(orµs
),ms
,s
,m
,h
. For example<wait10m>
or<wait1m20s>
.<XXXOn> <XXXOff>
- 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 thec
key down, you would use<cOn>
. Likewise,<cOff>
to release.{{ .HTTPIP }} {{ .HTTPPort }}
- The IP and port, respectively of an HTTP server that is started serving the directory specified by thehttp_directory
configuration parameter. Ifhttp_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.
We send each character to the VM with a default delay of 100ms between groups. The delay alleviates possible issues with latency and CPU contention. If you notice missing keys, you can tune this delay by specifying "boot_keygroup_interval" in your Packer template, for example:
Optional:
boot_keygroup_interval
(duration string | ex: "1h5m2s") - Time to wait after sending a group of key pressses. The value of this should be a duration. Examples are5s
and1m30s
which will cause Packer to wait five seconds and one minute 30 seconds, respectively. If this isn't specified, a sensible default value is picked depending on the builder type.boot_wait
(duration string | ex: "1h5m2s") - The time to wait after booting the initial virtual machine before typing theboot_command
. The value of this should be a duration. Examples are5s
and1m30s
which will cause Packer to wait five seconds and one minute 30 seconds, respectively. If this isn't specified, the default is10s
or 10 seconds. To set boot_wait to 0s, use a negative number, such as "-1s"boot_command
([]string) - 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.
http_ip
(string) - The IP address to use for the HTTP server started to serve thehttp_directory
. If unset, Packer will automatically discover and assign an IP.
Http directory configuration
Packer will create an http server serving http_directory
when it is set, a
random free port will be selected and the architecture of the directory
referenced will be available in your builder.
Example usage from a builder:
Optional:
http_directory
(string) - Path to a directory to serve using an HTTP server. The files in this directory will be available over HTTP that will be requestable from the virtual machine. This is useful for hosting kickstart files and so on. By default this is an empty string, which means no HTTP server will be started. The address and port of the HTTP server will be available as variables inboot_command
. This is covered in more detail below.http_content
(map[string]string) - Key/Values to serve using an HTTP server.http_content
works like and conflicts withhttp_directory
. The keys represent the paths and the values contents, the keys must start with a slash, ex:/path/to/file
.http_content
is useful for hosting kickstart files and so on. By default this is empty, which means no HTTP server will be started. The address and port of the HTTP server will be available as variables inboot_command
. This is covered in more detail below. Example:http_port_min
(int) - These are the minimum and maximum port to use for the HTTP server started to serve thehttp_directory
. Because Packer often runs in parallel, Packer will choose a randomly available port in this range to run the HTTP server. If you want to force the HTTP server to be on one port, make this minimum and maximum port the same. By default the values are8000
and9000
, respectively.http_port_max
(int) - HTTP Port Maxhttp_bind_address
(string) - This is the bind address for the HTTP server. Defaults to 0.0.0.0 so that it will work with any network interface.
Floppy configuration
floppy_img_path
(string) - Datastore path to a floppy image that will be mounted to the VM. Example:[datastore1] ISO/pvscsi-Windows8.flp
.floppy_files

([]string) - List of directories to copy files from.floppy_content
(map[string]string) - Key/Values to add to the floppy disk. The keys represent the paths, and the values contents. It can be used alongsidefloppy_files
orfloppy_dirs
, which is useful to add large files without loading them into memory. If any paths are specified by both, the contents infloppy_content
will take precedence.Usage example (HCL):
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'.
Connection Configuration

.
Location Configuration
vm_name
(string) - Name of the new VM to create.folder
(string) - VM folder to create the VM in.cluster
(string) - vSphere cluster where target VM is created. See the Working With Clusters And Hosts section above for more details.host

has multiple datastores.set_host_for_datastore_uploads
(bool) - Set this to true if packer should use the host for uploading files to the datastore. Defaults to false.
Run Configuration
boot_order
(string) - Priority of boot devices. Defaults todisk,cdrom
Shutdown Configuration
shutdown_command
(string) - Specify a VM guest shutdown command. This command will be executed using thecommunicator
. Otherwise, the VMware Tools are used to gracefully shutdown the VM.shutdown_timeout
(duration string | ex: "1h5m2s") - Amount of time to wait for graceful VM shutdown. Defaults to 5m or five minutes. This will likely need to be modified if thecommunicator
is 'none'.disable_shutdown
(bool) - Packer normally halts the virtual machine after all provisioners have run when noshutdown_command
is defined. If this is set totrue
, Packer will not halt the virtual machine but will assume that you will send the stop signal yourself through a preseed.cfg, a script or the final provisioner. Packer will wait for a default of five minutes until the virtual machine is shutdown. The timeout can be changed usingshutdown_timeout
option.
Wait Configuration
ip_wait_timeout
(duration string | ex: "1h5m2s") - Amount of time to wait for VM's IP, similar to 'ssh_timeout'. Defaults to 30m (30 minutes). See the Golang ParseDuration documentation for full details.ip_settle_timeout
(duration string | ex: "1h5m2s") - Amount of time to wait for VM's IP to settle down, sometimes VM may report incorrect IP initially, then its recommended to set that parameter to apx. 2 minutes.

- allow only ipv6 addresses192.168.1.0/24
- only allow ipv4 addresses from 192.168.1.1 to 192.168.1.254
ISO Configuration
By default, Packer will symlink, download or copy image files to the Packer
cache into a "hash($iso_url+$iso_checksum).$iso_target_extension
" file.
Packer uses hashicorp/go-getter in
file mode in order to perform a download.
go-getter supports the following protocols:
- Local files
- Git
- Mercurial
- HTTP
- Amazon S3
Examples:
go-getter can guess the checksum type based on iso_checksum
length, and it is
also possible to specify the checksum type.
In JSON:
In HCL2:
Required:
iso_checksum
(string) - The checksum for the ISO file or virtual hard drive file. The type of the checksum is specified within the checksum field as a prefix, ex: "md5:{$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 andiso_url
is used. Only one ofiso_url
oriso_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 toiso
.
CDRom Configuration
Each iso defined in the CDRom Configuration adds a new drive. If the "iso_url" is defined in addition to the "iso_paths", the "iso_url" is added to the VM first. This keeps the "iso_url" first in the boot order by default allowing the boot iso being defined by the iso_url and the vmware tools iso added from the datastore. Example:
cdrom_type
(string) - Which controller to use. Example:sata
. Defaults toide
.iso_paths
([]string) - List of Datastore or Content Library paths to ISO files that will be mounted to the VM. Here's an HCL2 example:
remove_cdrom
(bool) - Remove CD-ROM devices from template. Defaults tofalse
.
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.
Optional:
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):
Usage example (HCL):
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,
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 alongsidecd_files
, which is useful to add large files without loading them into memory. If any paths are specified by both, the contents incd_content
will take precedence.Usage example (HCL):
cd_label
(string) - CD Label

disk_controller_type
([]string) - Set VM disk controller type. Examplelsilogic
,lsilogic-sas
,pvscsi
,nvme
, orscsi
. Use a list to define additional controllers. Defaults tolsilogic
. See SCSI, SATA, and NVMe Storage Controller Conditions, Limitations, and Compatibility for additional details.storage
([]DiskConfig) - Configures a collection of one or more disks to be provisioned along with the VM. See the Storage Configuration.
Network Adapter Configuration
Defines a Network Adapter If no adapter is defined, network tasks (communicators, most provisioners) won't work, so it's advised to define one.
Example that creates two network adapters:
In JSON:
In HCL2:
network_card
(string) - Set VM network card type. Examplevmxnet3
.
Optional
network
(string) - Set the network in which the VM will be connected to. If no network is specified,host
must be specified to allow Packer to look for the available network. If the network is inside a network folder in vCenter, you need to provide the full path to the network.mac_address
(string) - Set network card MAC addresspassthrough
(*bool) - Enable DirectPath I/O passthrough
Storage Configuration
Defines the disk storage for a VM.
Example that will create a 15GB and a 20GB disk on the VM. The second disk will be thin provisioned:
In JSON:
In HCL2:
Example that creates 2 pvscsi controllers and adds 2 disks to each one:
In JSON:
In HCL2:

Export Configuration
You may optionally export an ovf from vSphere to the instance running Packer.
Example usage:
In JSON:
In HCL2:
The above configuration would create the following files:
Optional:
name
(string) - Name of the ovf. defaults to the name of the VMforce
(bool) - Overwrite ovf if it existsimages
(bool) - Deprecated: Images will be removed in a future release. Please seeimage_files
for more details on this argument.image_files
(bool) - In exported files, include additional image files that are attached to the VM, such as nvram, iso, img.manifest
(string) - Generate manifest using sha1, sha256, sha512. Defaults to 'sha256'. Use 'none' for no manifest.options
([]string) - Advanced ovf export options. Options can include:- mac - MAC address is exported for all ethernet devices
- uuid - UUID is exported for all virtual machines
- extraconfig - all extra configuration options are exported for a virtual machine
- nodevicesubtypes - resource subtypes for CD/DVD drives, floppy drives, and serial and parallel ports are not exported
For example, adding the following export config option would output the mac addresses for all Ethernet devices in the ovf file:
In JSON:
In HCL2:
Output Configuration:
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.directory_permission
(os.FileMode) - The permissions to apply to the "output_directory", and to any parent directories that get created for output_directory. By default this is "0750". You should express the permission as quoted string with a leading zero such as "0755" in JSON file, because JSON does not support octal value. In Unix-like OS, the actual permission may differ from this value because of umask.
Content Library Import Configuration
With this configuration Packer creates a library item in a content library whose content is a VM template or an OVF template created from the just built VM. The template is stored in a existing or newly created library item.
library
(string) - Name of the library in which the new library item containing the template should be created/updated. The Content Library should be of type Local to allow deploying virtual machines.name
(string) - Name of the library item that will be created or updated. For VM templates, the name of the item should be different from vm_name and the default is vm_name + timestamp when not set. VM templates will be always imported to a new library item. For OVF templates, the name defaults to vm_name when not set, and if an item with the same name already exists it will be then updated with the new OVF template, otherwise a new item will be created.Note: It's not possible to update existing library items with a new VM template. If updating an existing library item is necessary, use an OVF template instead by setting the ovf option as
true
.description
(string) - Description of the library item that will be created. Defaults to "Packer imported vm_name VM template".cluster
(string) - Cluster onto which the virtual machine template should be placed. If cluster and resource_pool are both specified, resource_pool must belong to cluster. If cluster and host are both specified, host must be a member of cluster. This option is not used when importing OVF templates. Defaults to cluster.folder
(string) - Virtual machine folder into which the virtual machine template should be placed. This option is not used when importing OVF templates. Defaults to the same folder as the source virtual machine.host
(string) - Host onto which the virtual machine template should be placed. If host and resource_pool are both specified, resource_pool must belong to host. If host and cluster are both specified, host must be a member of cluster. This option is not used when importing OVF templates. Defaults to host.resource_pool
(string) - Resource pool into which the virtual machine template should be placed. Defaults to resource_pool. if resource_pool is also unset, the system will attempt to choose a suitable resource pool for the virtual machine template.datastore
(string) - The datastore for the virtual machine template's configuration and log files. This option is not used when importing OVF templates. Defaults to the storage backing associated with the library specified by library.destroy
(bool) - If set to true, the VM will be destroyed after deploying the template to the Content Library. Defaults tofalse
.ovf
(bool) - When set to true, Packer will import and OVF template to the content library item. Defaults tofalse
.skip_import
(bool) - When set to true, the VM won't be imported to the content library item. Useful for setting totrue
during a build test stage. Defaults tofalse
.ovf_flags
([]string) - Flags to use for OVF package creation. The supported flags can be obtained using ExportFlag.list. If unset, no flags will be used. Known values: EXTRA_CONFIG, PRESERVE_MAC

Extra Configuration Parameters
configuration_parameters
(map[string]string) - configuration_parameters is a direct passthrough to the vSphere API's ConfigSpec: https://vdc-download.vmware.com/vmwb-repository/dcr-public/bf660c0a-f060-46e8-a94d-4b5e6ffc77ad/208bc706-e281-49b6-a0ce-b402ec19ef82/SDK/vsphere-ws/docs/ReferenceGuide/vim.vm.ConfigSpec.htmltools_sync_time
(bool) - Enables time synchronization with the host. Defaults to false.tools_upgrade_policy
(bool) - If sets to true, vSphere will automatically check and upgrade VMware Tools upon a system power cycle. If not set, defaults to manual upgrade.
Communicator configuration
Optional common fields:
communicator
(string) - Packer currently supports three kinds of communicators:none
- No communicator will be used. If this is set, most provisioners also can't be used.ssh
- An SSH connection will be established to the machine. This is usually the default.winrm
- A WinRM connection will be established.
In addition to the above, some builders have custom communicators they can use. For example, the Docker builder has a "docker" communicator that uses
docker exec
anddocker cp
to execute scripts and copy files.pause_before_connecting
(duration string | ex: "1h5m2s") - We recommend that you enable SSH or WinRM as the very last step in your guest's bootstrap script, but sometimes you may have a race condition where you need Packer to wait before attempting to connect to your guest.If you end up in this situation, you can use the template option
pause_before_connecting
. By default, there is no pause. For example if you setpause_before_connecting
to10m
Packer will check whether it can connect, as normal. But once a connection attempt is successful, it will disconnect and then wait 10 minutes before connecting to the guest and beginning provisioning.
Optional SSH fields:
ssh_host
(string) - The address to SSH to. This usually is automatically configured by the builder.ssh_port
(int) - The port to connect to SSH. This defaults to22
.ssh_username
(string) - The username to connect to SSH with. Required if using SSH.ssh_password
(string) - A plaintext password to use to authenticate with SSH.ssh_ciphers
([]string) - This overrides the value of ciphers supported by default by Golang. The default value is [ "aes128-gcm@openssh.com", "chacha20-poly1305@openssh.com", "aes128-ctr", "aes192-ctr", "aes256-ctr", ]Valid options for ciphers include: "aes128-ctr", "aes192-ctr", "aes256-ctr", "aes128-gcm@openssh.com", "chacha20-poly1305@openssh.com", "arcfour256", "arcfour128", "arcfour", "aes128-cbc", "3des-cbc",
ssh_clear_authorized_keys
(bool) - If true, Packer will attempt to remove its temporary key from~/.ssh/authorized_keys
and/root/.ssh/authorized_keys
. This is a mostly cosmetic option, since Packer will delete the temporary private key from the host system regardless of whether this is set to true (unless the user has set the-debug
flag). Defaults to "false"; currently only works on guests withsed
installed.ssh_key_exchange_algorithms
([]string) - If set, Packer will override the value of key exchange (kex) algorithms supported by default by Golang. Acceptable values include: "curve25519-sha256@libssh.org", "ecdh-sha2-nistp256", "ecdh-sha2-nistp384", "ecdh-sha2-nistp521", "diffie-hellman-group14-sha1", and "diffie-hellman-group1-sha1".ssh_certificate_file

, a PTY will be requested for the SSH connection. This defaults tofalse
.ssh_timeout
(duration string | ex: "1h5m2s") - The time to wait for SSH to become available. Packer uses this to determine when the machine has booted so this is usually quite long. Example value:10m
. This defaults to5m

is set.ssh_disable_agent_forwarding
(bool) - If true, SSH agent forwarding will be disabled. Defaults tofalse
.ssh_handshake_attempts
(int) - The number of handshakes to attempt with SSH once it can connect. This defaults to10
, unless assh_timeout
is set.ssh_bastion_host
(string) - A bastion host to use for the actual SSH connection.ssh_bastion_port
(int) - The port of the bastion host. Defaults to22
.ssh_bastion_agent_auth

(string) - The username to connect to the bastion host.ssh_bastion_password
(string) - The password to use to authenticate with the bastion host.ssh_bastion_interactive
(bool) - Iftrue
, the keyboard-interactive used to authenticate with bastion host.ssh_bastion_private_key_file

(string) - Path to user certificate used to authenticate with bastion host. The~
can be used in path and will be expanded to the home directory of current user.ssh_file_transfer_method
(string) -scp
orsftp
- How to transfer files, Secure copy (default) or SSH File Transfer Protocol.NOTE: Guests using Windows with Win32-OpenSSH v9.1.0.0p1-Beta, scp (the default protocol for copying data) returns a a non-zero error code since the MOTW cannot be set, which cause any file transfer to fail. As a workaround you can override the transfer protocol with SFTP instead
ssh_file_transfer_protocol = "sftp"
.ssh_proxy_host
(string) - A SOCKS proxy host to use for SSH connectionssh_proxy_port
(int) - A port of the SOCKS proxy. Defaults to1080

) to disable. Example value:10s
. Defaults to5s
.ssh_read_write_timeout
(duration string | ex: "1h5m2s") - The amount of time to wait for a remote command to end. This might be useful if, for example, packer hangs on a connection after a reboot. Example:5m
. Disabled by default.ssh_remote_tunnels

([]string) -
ssh_private_key_file
(string) - Path to a PEM encoded private key file to use to authenticate with SSH. The~
can be used in path and will be expanded to the home directory of current user.
Optional WinRM fields:
winrm_username
(string) - The username to use to connect to WinRM.winrm_password
(string) - The password to use to connect to WinRM.winrm_host
(string) - The address for WinRM to connect to.NOTE: If using an Amazon EBS builder, you can specify the interface WinRM connects to via
ssh_interface
winrm_no_proxy
(bool) - Setting this totrue
adds the remotehost:port
to theNO_PROXY
environment variable. This has the effect of bypassing any configured proxies when connecting to the remote host. Default tofalse
.winrm_port
(int) - The WinRM port to connect to. This defaults to5985
for plain unencrypted connection and5986
for SSL whenwinrm_use_ssl
is set to true.winrm_timeout
(duration string | ex: "1h5m2s") - The amount of time to wait for WinRM to become available. This defaults to30m
since setting up a Windows machine generally takes a long time.winrm_use_ssl
(bool) - Iftrue
, use HTTPS for WinRM.winrm_insecure
(bool) - Iftrue
, do not check server certificate chain and host name.winrm_use_ntlm
(bool) - Iftrue
, NTLMv2 authentication (with session security) will be used for WinRM, rather than default (basic authentication), removing the requirement for basic authentication to be enabled within the target guest. Further reading for remote connection authentication can be found here.

Required vSphere Privileges
It is recommended to create a custom vSphere role with the required privileges to integrate Packer with vSphere. Accounts or groups can be added to the role to ensure that Packer has the least privileged access to the infrastructure. For example, a named service account (e.g. svc-packer-vsphere@example.com).
Clone the default Read-Only vSphere role and add the following privileges, which are based on the capabilities of the vsphere-iso
plugin:
Category | Privilege | Reference |
---|---|---|
Content Library | Add library item | ContentLibrary.AddLibraryItem |
... | Update Library Item | ContentLibrary.UpdateLibraryItem |
Datastore | Allocate space | Datastore.AllocateSpace |
... | Browse datastore | Datastore.Browse |
... | Low level file operations | Datastore.Browse |
Network | Assign network | Network.Assign |

Global permissions are required for the content library based on the hierarchical inheritance of permissions. Once the custom vSphere role is created, assign Global Permissions in vSphere to the accounts or groups used for the Packer to vSphere integration, if using the content library.
For example:
- Log in to the vCenter Server at https://<management_vcenter_server_fqdn>/ui as
administrator@vsphere.local
. - Select Menu > Administration.
- In the left pane, select Access control > Global permissions and click the Add permissions icon.
- In the Add permissions dialog box, enter the service account (e.g. svc-packer-vsphere@example.com), select the custom role (e.g. Packer to vSphere Integration Role) and the Propagate to children check box, and click OK.
In an environment with many vCenter Server instances, such as management and workload, in enhanced linked-mode, you may wish to further reduce the scope of access across the vSphere infrastructure. For example, if you do not want Packer to have access to the management vCenter Server instance, but only allow access to workload vCenter Server instances:
- From the Hosts and clusters inventory, select management vCenter Server to restrict scope, and click the Permissions tab.
- Select the service account with the custom role assigned and click the Change role icon.
- In the Change role dialog box, from the Role drop-down menu, select No Access, select the Propagate to children check box, and click OK.
