6.2. Before You Begin

6.2.1. Prerequisites

To install and run virt-who:
  • You must have credentials that allow virt-who to communicate with:
    • a Satellite user account
    • your virtualization system
  • The system running virt-who is registered already to the Satellite server(virt-who will use the host credentials).
  • The ports configured for your hypervisor allow communication (the default virt-who port is 443).

6.2.2. User Login for virt-who

Login credentials to the data center are required for the following hypervisor types:
  • Red Hat Enterprise Virtualization Manager
  • VMware vSphere
  • Microsoft Hyper-V

Note

When configuring the permissions to the login credentials, the permissions must allow access to the virtual machines and hypervisors. Red Hat recommends the following:
  • The login has read-only permission.
  • The login is for a service account or non-user login.
  • The password does not expire.
