Introduction The Hyper-V package for Hornbill's IT Operations Management (ITOM) contains operations to automate the management of Hyper-V environments.

Target Environment Requirements

Script Execution Machine Requirements

• The HyperV PowerShell module needs to installed on the machine that will be executing the scripts (the correct Hyper-V Management Package for your OS);
• If the script execution policy on the machine executing these operations is set to Restricted, then this will need to be updated to something less restrictive. See the PowerShell Documentation for more information.

KeySafe Configuration

When creating SIS jobs for operations contained within this package, they need to be run on the target machine as a user who has the correct privileges on the target.

To configure your Target Machine account authentication in KeySafe:

• In the Admin console, navigate to: System > Security > KeySafe;
• Click on + then select Username + Password;
• Give the KeySafe Key a Title (this is the name/identifier for the target machine account as you will see it when creating an IT Automation Job, or adding an IT Automation node to a Business Process or Runbook);
• Optionally add a description;
• Populate the Username field with the domain/local account username for the account being used on the target machine;
• Populate the Password field with the password for the above account;
• Select Create Key to save.

Once you have created your KeySafe Key, you can then use it when creating IT Automation Jobs from this package. See screenshots to the right for examples.
