4. Installing and updating Virtuozzo Hybrid Server CloudBlue connector inside Linux environment¶

4.1.1. Virtual environment requirements¶

1. Create a virtual environment running Virtuozzo Linux 7 with an Internet connection that enables outbound access to the Virtuozzo Hybrid Server CloudBlue connector.

2. Install, configure, and start the Virtuozzo Hybrid Server CloudBlue connector service inside the virtual environment.

4.1.2. Infrastructure requirements¶

Virtuozzo Automator and PowerPanel must be deployed and accessible:

1. Install PowerPanel and Virtuozzo Automator on the virtual environment.

2. Provide inbound access to PowerPanel.

3. Ensure there is connectivity from PowerPanel and Virtuozzo Automator to the Virtuozzo Hybrid Server node cluster’s internal network.

4. Restrict access to Virtuozzo Automator. It should be accessible to the administrators of the system only.

For more details, refer to the Virtuozzo Automator Administrator’s Guide and the Virtuozzo PowerPanel Administrator’s Guide.

4.1.3. Internal communications and ports¶

The Virtuozzo Hybrid Server CloudBlue connector installed on Virtuozzo Automator must be connected with the PowerPanel controller, installed on a dedicated virtual environment (virtual machine or container), via the keystone port 35357. By default, the port is open locally and closed for external communications. Open it only for your local network inside the PowerPanel controller and make this rule permanent. For example:

firewall-cmd --permanent --zone=public --add-port=35357/tcp ; firewalld-cmd --reload

Use the following CLI command inside a local network to check that the port is open:

curl https://PowerPanel_Controller_Hostname:35357/v3 --insecure

For more details about authentication, refer to Authentication.

For more details about ports, refer to Appendix A: Controller and compute ports.

4.1.4. Resource requirements¶

The recommended amount of virtual environment resources, such as RAM, CPU, etc., are specified in your subscription service plan. Additionally, ensure that all mandatory parameters for your virtual environments are listed and saved in the subscription service plan.
