Parallels Desktop Preferences

prlsrvctl set

The prlsrvctl set command is used to modify Parallels Desktop preferences. The available parameters and options are described below.

Parameters

--mem-limit <auto | size>

Sets the total memory allocated to Parallels Desktop and its virtual machines. The auto option optimizes memory usage. The size option allows the user to set the memory size manually.

-s, --min-security-level <low | normal | high>

Specifies the minimum connection security level to connect to the server. Low - no transmitted data is encrypted. Normal - only the most important data is encrypted. High - all transmitted data is encrypted.

-c, --cep <on | off>

Enables or disables participation in the Customer Experience Program.

--verbose-log <on | off>

Enables or disables verbose logging.

--log-rotation <on | off>

Enables or disables automatic rotation of the Parallels Dispatcher Service and virtual machine log files.

--allow-to-confirm [--host-admin <name>]

Forces the prompt to enter admin credentials or a custom password if an operation requires it. If no operation requires a password, this option will be ignored. If an operation requires a password but this option is omitted, the operation will fail with a corresponding error.

To make an operation require a password, use the following options: --require-pwd, --require-custom-pwd, or --lock-edit-settings, as described below.

The [--host-admin <name>] option specifies the host administrator name if an administrator password is required to unlock the Parallels Desktop preferences for editing.

--allow-attach-screenshots <on | off>

Enables or disables attaching virtual machine and host screenshots to a problem report.

--require-pwd <create-vm | add-vm | remove-vm | clone-vm>:<on | off>

Require entering an administrator password to perform a corresponding action (create a VM, add a VM, etc.). Use --allow-to-confirm to make the system ask for username and password.

--require-custom-pwd <create-vm | add-vm | remove-vm | clone-vm | edit-preferences>:<on | off>

Require entering a custom password to perform a corresponding action. Use --allow-to-confirm to make the system ask for username and password. Other options are self-explanatory.

--custom-pwd [--custom-pwd-mode <on | off | change>] [--replace-commands]

Set, reset, or change the custom password for operations that require it. See the explanation of the parameters below.

--custom-pwd-mode <on | off | change> — set, reset, or change the custom password for operations which require it.

--replace-commands — specify this option to reset commands that are protected with the admin password. This means that when you enable a custom password, commands that require the admin password will now require a custom password. Commands that previously required a custom password will be discarded. The same logic is used when you switch back to the admin password (set --custom-pwd-mode to off). When you disable a custom password, commands that require it will now require the admin password. Commands that previously required the admin password will be discarded. This option is ignored if --custom-pwd-mode is set to change.

--lock-edit-settings <on | off [--host-admin <name>]>

Locks or unlocks Parallels Desktop preferences for editing. The --host-admin parameter specifies the host administrator name if an administrator password is required to unlock Parallels Desktop preferences for editing.

--external-dev-auto-connect <host | guest | ask>

When a new external device is attached to the Mac, connect it to the host, or guest, or ask the user what to do.

--default-encryption-plugin <plugin-id>

Sets the default encryption plugin.

--reset-default-encryption-plugin

Resets the default encryption plugin.

--hide-license-request-params <on | off>

Hides the host name and username in requests to Parallels Licensing Server.
