With remarkable development enhancements taking place in RHV, specifically for robust OVS integration, there are changes that CloudForms needs to take in account for customized VM instances provisioning. This is the case for setting the target networks in the provisioning process of services items.
In previous versions of RHV v4.2, the CloudForms provisioning statemachine used the vlan name as the input for the method set_vlan(vlan), but from version RHV v4.2 it started to use vNIC profiles ID instead. At first glance it should not change anything but single parameter that would be retrieved from the VMDB. However at the time that this blog is being written the vNIC profile ID is not yet stored in the CloudForms database.
The way to overcome this limitation is by making a direct connection to RHV and retrieve vNIC profile information. And thereafter make it available to the methods in the startemachine provisioning.
As a background knowledge it worth to mention that a Virtual Network Interface Card (vNIC) profile is a collection of settings that can be applied to individual virtual network interface cards in the Manager. It offers an added layer of administrative flexibility that defines how to use (consume) these profiles, and how it can be granted to specific users. The idea behind vNIC profiles is to enable the administrators to control the quality of service that different users receive from a given network.
There is a great number possibilities for rich customization while integrating RH CloudForms and RHV. This repo contains a datastore domain called "Automate". Within this domain there are several Namespaces that allow to configure the below use cases with a minimal effort.
Requirements
- To have installed and configured a CFME appliance
- To have a Red Hat Virtualization instance integrated in CloudForms
- To have at least one VM template deployed in RHV
Integrating Procedure
Login to your CFME appliance and navigate to: Automation > Automate > Import/Export
Edit the fields as follows:
Leave the rest of the fields unchanged and click Submit!
It shall appear the bellow window, just click submit and it will be all settled.
Navigate to: Automation > Automate > Explorer, the Automate domain should appear as below:
Service Catalog Dialog
Objective: to create a Service Catalog Item that will prompt existing VLANs in RHV and set the desire one for the provisioning request.
Steps:
1- Create the Service Dialog. Navigate to: Automation > Automate > Customization > Service Dialogs
It should at least have four fields with the below configuration
Field 1 : RHV Provider
Type: Dropdown
Data:
Field Information
- Label: RHV Provider
- Name: rhv_ems
- Dynamic: Yes
Options
- Entry Point: ServiceDialog/Class/rhv_providers_listing
- Show Refresh Button: Yes
- Load values on init: Yes
- Required: Yes
- Value type: String
- Multiselect: No
- Fields to refresh: Datacenter
No change is needed in the Advance or Overridable Options section
Field 2 : Datacenter
Type: Dropdown
Data:

- Entry Point: ServiceDialog/Class/vnic_profile_listing
- Show Refresh Button: Yes
- Load values on init: No
- Required: Yes
- Value type: String
- Multiselect: No
- Fields to refresh: Nothing Selected
No change is needed at the Advance or Overridable Options
2- Create the Service Catalog Item. Navigate to: Services > Catalogs > Catalogs
First create a new Catalog, by clicking in the configuration button, then follow and complete the form.
-
Name: RHV
-
Once the Catalog is available, proceed to create the Service Catalog Item, Navigate to: Services > Catalogs > Catalogs Items
It should have the following configuration:
Adding a new Service Catalog Item
Catalog Item Type: Red Hat Virtualization
=>
Basic Info:
- Name / Description: RHV VM Provisioning / RHV VM Provisioning (Tick Display in Catalog)
- Catalog: My Company/RHV
- Dialog: rhv_vm_provision_dialog
Details:
No configuration needed
Request Info:
- First select a VM Template
- Set all the Required fields (The network will be overwritten with the information from the Service Dialog)
- VM Name: changeme
The Service Catalog Item should look like...
It is done!
