10 Post-deployment steps

The chapter describes registration of SLE Micro and covers extensions available for SLE Micro.

10.1 Registration

Registering the system is possible from the command line using the transactional-update register command. For information that goes beyond the scope of this section, refer to the inline documentation with SUSEConnect --help

Procedure 10.1: Product registration with SUSEConnect
  1. To register SUSE Linux Enterprise Micro with SUSE Customer Center, run transactional-update register as follows:

    # transactional-update register -r REGISTRATION_CODE -e EMAIL_ADDRESS

    To register with a local registration server, additionally provide the URL to the server:

    # transactional-update register -r REGISTRATION_CODE -e EMAIL_ADDRESS \
    --url "https://suse_register.example.com/"

    Replace REGISTRATION_CODE with the registration code you received with your copy of SUSE Linux Enterprise Micro. Replace EMAIL_ADDRESS with the e-mail address associated with the SUSE account you or your organization uses to manage subscriptions.

  2. Reboot your system to switch to the latest snapshot.

  3. SUSE Linux Enterprise Micro is now registered.

10.2 Managing extensions

SLE Micro supports the kernel live patching extension. Bear in mind that the extension might require an additional subscription.

Note: SUSE Linux Enterprise Live Patching availability

The SUSE Linux Enterprise Live Patching extension is available only for the x86 (except for the real-time kernel) and IBM Z architectures.

As the extension activation or deactivation is performed as a transactional-update and thus creates a new snapshot, you need to restart your system to boot to the new snapshot and apply the changes.

10.2.1 Activating SUSE Linux Enterprise Live Patching

To active the SUSE Linux Enterprise Live Patching proceed as follows:

  1. List available extensions by running:

    # transactional-update --quiet register -list-extensions
  2. The output provides you with a command regarding how to activate the live patching extension. You can skip this step if you activated the extension during the manual installation.

    # transactional-update register -p sle-module-live-patching/15.3/x86_64 \
      -r registration code
  3. After activating the SUSE Linux Enterprise Live Patching extension, configure libzypp in the /etc/zypp/zypp.conf file as follows:

    multiversion = provides:multiversion(kernel)

    to keep the current kernel running while patching the system, otherwise you may get dependency conflicts while kernel updates are being applied.

    multiversion.kernels = latest

    after applying the live patch, a cleanup of kernels is performed in the new snapshot. If not set, the snapshot keeps the previous kernel and performs kernel updates also on the previous kernel.

  4. Additionally, set LIVEPATCH_KERNEL='always' in the /etc/sysconfig/livepatching file.

    Note: Matching version of the kernel-default-livepatch and kernel

    To ensure that the live patches will be installed even after the kernel upgrade, install the matching version of the kernel-default-livepatch package.

  5. Now install the extension by running:

    # transactional-update pkg install kernel-default-livepatch
  6. Reboot your system to switch to the new snapshot.

10.2.2 Deactivating SUSE Linux Enterprise Live Patching

To deactivate the extension, run the following command:

# transactional-update register -d \
  -p sle-module-live-patching/15.3/x86_64
