OSP 15.png
15. Now, let's start configuring the settings.

Note: The below description refers to the "VHI" product configuration.


  • Default Domain - choose a default domain for new projects based on this product.
  • Client Projects Mode - select a preferred mode that defines how new hostings will be created.
  • Project User Roles - define default roles for a new user. Keep in mind that the choice of roles determines the level of allowed permissions. For example, select the image_upload role if you wish to be allowed to upload OS images.
    • Inherit Domain Roles - enable if the Domain User Role should be inherited from the Project User Roles or defined separately.
      Note that this option is dependent on the 'Default Domain' setting. More about User Roles can be found here.
    • Domain User Roles - if the above 'Inherit Domain Roles' is disabled, this setting appears; here you may choose a default role in the domain for a new user based on this product.
      This setting, if not left empty, overwrites the 'with and without domain permissions' selections in the 'Client Projects Mode' option.
  • Hide User Password - enable to hide the user password after project creation, the feature is particularly useful for authentication with the OpenID protocol.
  • OpenStack Panel Web Address - is the web address for the login page to the OpenStack panel.
  • Default Domain Name - enter a domain that will be used when the domain name is not provided. Available variables: {clientId}, {serviceId} and {rand}.
  • Default Project Name - enter a project name that will be used when creating a new project. If left empty, the domain name will be used instead. Available variables: {clientId}, {serviceId} and {rand}.
  • Default User Name - enter a user name that will be used when creating a new user. Available variables: {clientId}, {serviceId} and {rand}.
  • Domain Field Content - specify the content data that will overwrite the WHMCS Domain Field.
  • Client Area Login Information - select which of the login elements should be visible in the "Server Information" table in the client area. Choose from: username, password, domain and web address.
  • Log API Requests - if you enable, information on API requests will be stored in the 'Module Log' section in your WHMCS.
  • Login Restrictions - this enables a feature, that enhances security by only issuing temporary passwords which ensure access is granted only for as long as it is needed.
  • Remove Password - if enabled, the password will be removed from the database as soon as the project is created.
OSP 16.png

Compute, Block-Storage, Network, Load Balancer, Container Infrastructure, Traits, QoS Policy: 'Minimum Bandwidth Rate Rules' and 'Bandwidth Limit Rules' -
these sections may vary depending on the project, some of them might be unavailable for your OpenStack project. You may easily adjust your product to your needs by modifying the available options. Type '-1' for unlimited.
Note: Keep in mind that in the case of Virtuozzo server 'Traits' stand for 'Placement Groups' endpoints.

OSP 16 1.png

Module Custom Web Hooks - here you may add the URL with WHMCS parameters to perform additional actions after the create/suspend/unsuspend/terminate/change package actions.

OSP 16 2.png

Module Custom Shell Hooks - enter the commands with WHMCS parameters to perform additional actions after the create/suspend/unsuspend/terminate/change package actions.
Please refer to the following section to correctly set up the openID configuration to connect to VHI correctly.

OSP 16 0.png
16. Optionally, you may configure the "Usage Billing Settings" that will be utilized for the Advanced Billing For WHMCS integration.

Select specific networks and IP address versions for custom parameter calculations.

OSP 16 4.png
17. At the end of the configuration process, you can enable 'Metric Billing' and decide whether you want to generate configurable options for the product.

Configurable options can be used by your clients to select each virtual machine parameter individually during order placement.
Otherwise, if configurable options are not defined, then the fixed parameters specified in the earlier configuration will be used instead.
If you decide to use configurable options, select the configurable options unit and then press the 'Create Configurable Options' button.

There is also an 'Alternative Mode' available, which changes the way the configurable options values are verified and calculated.
Select single configurable options and their values will be summed with the default product configuration values instead of overwriting them.

OSP 16 3.png
OSP 17.png
Now, select which options you want to generate and confirm by clicking 'Create' .
Note that the configuration for disabled options will still be taken from the configuration of the main product.
More information about how to use configurable options can be found here or in the official WHMCS documentation.

User Roles Configuration

Roles, or in other words permissions, in OpenStack can be assigned to users, they can be associated with either a domain or a project.
  • Domain - on top of the hierarchy in OpenStack, domain includes all projects and users
    • User - a user can have domain roles and project roles assigned, when you log into OpenStack, you log into a user
    • Project - projects are created with the OpenStack Project For WHMCS module. It includes all remaining elements that are visible after logging into the user's panel, for example: virtual machines or networks
Move to 'Products/Services' → 'Module Settings' → 'Configuration'. There you will find all the options associated with the roles configuration:
OSP 18 1.png
  • Default Domain:
    • {exemplary_domain} - 'Project' and ' User' are created in a selected domain; the 'Inherit Domain Roles' switcher and 'Domain User Roles' dropdown disappear, this is where permissions to the domain are not granted
    • Create New One - if this option is selected, look at the 'Client Projects Mode' setting, as its selection is decisive now (a new domain per client or per service in WHMCS is created, all client services must have all projects assigned to one domain).
  • Client Projects Mode
    • Default - every hosting creates a new domain (project and user), in this case name generated in 'Default Domain Name' should be unique (e.g. dependent on the Service ID in WHMCS)
    • Only one domain per client (with domain permissions) - the first service of the clients creates a domain, every next one assigns project and the new user to that domain (a user has all the permissions to the domain)
    • Only one domain per client (without domain permissions) - the first service of the clients creates a domain, every next one assigns project and the new user to that domain (a user has no permissions to the domain)
    • Only one domain and user per client - the first service of the client creates a domain and a user, every next service creates a project only within the existing domain
  • Project User Roles - assigning project roles to a user, for example you need to select here the "image_upload" role to allow uploading images
  • Inherit Domain Roles - if enabled, the user has the same roles assigned for both the domain and for the project
  • Domain User Roles - if the above 'Inherit Domain Roles' option is disabled, the user has the selected here domain roles assigned and the 'with/without domain permissions' settings are overwritten.
    If left empty, the 'with/without domain permissions' setting is taken into consideration.
Important: When upgrading from 1.3.0 to 1.4.0 module version and you do not save changes in the module settings the roles will work as in the previous version.


OpenStack Projects For WHMCS is a module that will allow you to provision virtual projects to your customers in a fully automatic manner.

Addon Module

While management of specific projects mostly takes place in the admin area, functions that affect the whole module can be found in the addon.
See the section below for an in depth explanation of each of them.


Cron job tasks sent to the server through the module can be viewed and managed here.
The basic information includes:
  • ID - identification number unique to each task.
  • Related Item - the product related to the task. Clicking on it will take you to its product page.
  • Status - the current status of the task (finished, running, pending, waiting or error).
  • Task - specific action that the task attempts to run, these are:
    • Lock Account
    • Suspend Resources
    • Unsuspend Resources
    • Terminate Resources
  • Attempts - the number of times the task was attempted.
  • Created At - the date when the task was first created.
  • Updated At - the date when the status of the task was last updated.
OSP 18 2.png
On the right side of the tasks list you will find the action buttons. These are in order:
  • Details - access more in-depth information about the task, including error logs.
  • Run - attempt to run the task one more time.
  • Delete - remove the task from the queue and the list.
OSP 18 3.png
Moreover, you can change additional settings by clicking on the three dots above the basic actions.
  • Auto Prune - toggle the switch on to enable the task auto prune feature, which will delete the tasks after the specified time has passed.
  • Auto Prune Older Than - specify the number of days that have to pass before a task is automatically pruned.
OSP 18 6.png
Remember to make use of the search bar when you need to find a specific task, and the mass action feature, when you need to delete multiple tasks at once.
OSP 18 4.png


Customizing language files is now extremely easy with the "Translations" tool that is now available directly in the addon.
Its user-friendly design makes managing various language file tweaks a smooth and efficient process.
