Chapter 7: Enterprise Linux Hosts

Installing Enterprise Linux Hosts

An Enterprise Linux host (such as CentOS or RHEL), also known as an EL-based hypervisor is based on a standard basic installation of an Enterprise Linux operating system on a physical server.

The host must meet the minimum Host requirements out lined in Chapter 2: System Requirements.

See Appendix G, Configuring a Host for PCI Passthrough for more information on how to enable the host hardware and software for device passthrough.

Important: Virtualization must be enabled in your host's BIOS settings. For information on changing your host's BIOS settings, refer to your host's hardware documentation.

Important: Third-party watchdogs should not be installed on Red Hat Enterprise Linux hosts, as they can interfere with the watchdog daemon provided by VDSM.

Installing Cockpit on Enterprise Linux Hosts

You can install a Cockpit user interface for monitoring the host’s resources and performing administrative tasks.

Installing Cockpit on Enterprise Linux Hosts

  1. By default, when adding a host to the oVirt Engine, the Engine configures the required firewall ports. See Chapter 8: Adding a Host to the oVirt Engine for details. However, if you disable Automatically configure host firewall when adding the host, manually configure the firewall according to the “Host Firewall Requirements” in Chapter 2: System Requirements.

  2. Install the dashboard packages:

    # yum install cockpit-ovirt-dashboard

  3. Enable and start the cockpit.socket service:

    # systemctl enable cockpit.socket # systemctl start cockpit.socket

  4. You can log in to the Cockpit user interface at https://HostFQDNorIP:9090.
