Chapter 6. Installing Hosts for Red Hat Virtualization

Procedure

1. Go to the Get Started with Red Hat Virtualization on the Red Hat Customer Portal and log in.
2. Click Download Latest to access the product download page.
3. Choose the appropriate Hypervisor Image for RHV from the list and click Download Now.
4. Start the machine on which you are installing RHVH, booting from the prepared installation media.

5. From the boot menu, select Install RHVH 4.4 and press Enter.

   Note

   You can also press the Tab key to edit the kernel parameters. Kernel parameters must be separated by a space, and you can boot the system using the specified kernel parameters by pressing the Enter key. Press the Esc key to clear any changes to the kernel parameters and return to the boot menu.

6. Select a language, and click Continue.
7. Select a keyboard layout from the Keyboard Layout screen and click Done.

8. Select the device on which to install RHVH from the Installation Destination screen. Optionally, enable encryption. Click Done.

   Important

   Use the Automatically configure partitioning option.

9. Select a time zone from the Time & Date screen and click Done.

10. Select a network from the Network & Host Name screen and click Configure…​ to configure the connection details.

    Note

    To use the connection every time the system boots, select the Connect automatically with priority check box. For more information, see Configuring network and host name options in the Red Hat Enterprise Linux 8 Installation Guide.

    Enter a host name in the Host Name field, and click Done.

11. Optional: Configure Security Policy and Kdump. See Customizing your RHEL installation using the GUI in Performing a standard RHEL installation for Red Hat Enterprise Linux 8 for more information on each of the sections in the Installation Summary screen.
12. Click Begin Installation.

13. Set a root password and, optionally, create an additional user while RHVH installs.

    Warning

    Do not create untrusted users on RHVH, as this can lead to exploitation of local security vulnerabilities.

14. Click Reboot to complete the installation.

    Note

    When RHVH restarts, nodectl check performs a health check on the host and displays the result when you log in on the command line. The message node status: OK or node status: DEGRADED indicates the health status. Run nodectl check to get more information.

    Note

    If necessary, you can prevent kernel modules from loading automatically.

Registering RHVH with the Content Delivery Network

1. Register your system with the Content Delivery Network, entering your Customer Portal user name and password when prompted:

   # subscription-manager register

2. Enable the Red Hat Virtualization Host 8 repository to allow later updates to the Red Hat Virtualization Host:

   # subscription-manager repos --enable=rhvh-4-for-rhel-8-x86_64-rpms

Registering RHVH with Red Hat Satellite 6

1. Log in to the Cockpit web interface at https://HostFQDNorIP:9090.
2. Click Terminal.

3. Register RHVH with Red Hat Satellite 6:

     # rpm -Uvh http://satellite.example.com/pub/katello-ca-consumer-latest.noarch.rpm
     # subscription-manager register --org="org_id"
     # subscription-manager list --available
     # subscription-manager attach --pool=pool_id
     # subscription-manager repos \
       --disable='*' \
       --enable=rhvh-4-for-rhel-8-x86_64-rpms

Procedure

1. Register your system with the Content Delivery Network, entering your Customer Portal user name and password when prompted:

   # subscription-manager register

2. Find the Red Hat Enterprise Linux Server and Red Hat Virtualization subscription pools and record the pool IDs:

   # subscription-manager list --available

3. Use the pool IDs to attach the subscriptions to the system:

   # subscription-manager attach --pool=poolid

   Note

   To view currently attached subscriptions:

   # subscription-manager list --consumed

   To list all enabled repositories:

   # dnf repolist

4. Configure the repositories:

   # subscription-manager repos \
       --disable='*' \
       --enable=rhel-8-for-x86_64-baseos-eus-rpms \
       --enable=rhel-8-for-x86_64-appstream-eus-rpms \
       --enable=rhv-4-mgmt-agent-for-rhel-8-x86_64-rpms \
       --enable=fast-datapath-for-rhel-8-x86_64-rpms \
       --enable=advanced-virt-for-rhel-8-x86_64-rpms \
       --enable=openstack-16.2-cinderlib-for-rhel-8-x86_64-rpms \
       --enable=rhceph-4-tools-for-rhel-8-x86_64-rpms \
       --enable=rhel-8-for-x86_64-appstream-tus-rpms \
       --enable=rhel-8-for-x86_64-baseos-tus-rpms

5. Set the RHEL version to 8.6:

   # subscription-manager release --set=8.6

6. Ensure that all packages currently installed are up to date:

   # dnf upgrade --nobest

7. Reboot the machine.

   Note

   If necessary, you can prevent kernel modules from loading automatically.

Procedure

1. Install the dashboard packages:

   # dnf install cockpit-ovirt-dashboard

2. Enable and start the cockpit.socket service:

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

3. Check if Cockpit is an active service in the firewall:

   # firewall-cmd --list-services

   You should see cockpit listed. If it is not, enter the following with root permissions to add cockpit as a service to your firewall:

   # firewall-cmd --permanent --add-service=cockpit

   The --permanent option keeps the cockpit service active after rebooting.
