Chapter 1. Understanding Cockpit

1.1. Understanding the oVirt Machines tab

The oVirt Machines tab provides an overview of the virtual machines running in the hyperconverged cluster.

To view this tab, browse to the Cockpit interface for your server (for example, http://server1.example.com:9090), log in, and click the hostname and oVirt Machines.

The Hosts subtab of the oVirt Machines tab in Cockpit

This tab is divided into a number of subtabs.

Host: The Host subtab shows information about virtual machines that are available on this virtualization host. Clicking on each virtual machine shows a summary of that machine, as well as various management operations. See Managing virtual machines using Cockpit for more information about virtual machine operations.
Cluster: The Cluster subtab shows information about virtual machines that are available in the hyperconverged cluster. The Host column lets you easily navigate to the appropriate location for managing each virtual machine. The Action column shows any operations you can perform from this virtualization host.
