Live Patching Support

In this article

    The live patching technology allows you to patch a running Linux kernel without the need to reboot or change kernel-related files on the disk.

    If you plan to use live patching, consider the following limitations:

    • Only kGraft, kpatch and Ksplice kernel extensions are supported.
    • Live patching is supported only for the following Linux distributions:
    • SLES 11 SP4, 12 SP2 – 15 SP3
    • SLES for SAP 11 SP4, 12 SP2 – 15 SP3
    • RHEL 6.0 – 8.5
    • Oracle Linux 6 – 8.5 (RHCK)
    • Oracle Linux 6 (starting from UEK R2) – Oracle Linux 8 (up to UEK R6 U2, kernel version 5.4.17-2102)

    Before live patching, check the following prerequisites:

    • Before you start live patching on a production environment, make sure that a kernel patch does not harm your system in any way using a spare Veeam Agent computer.
    • Back up an entire Veeam Agent computer before live patching.
    • Make sure that there is no backup jobs running on the Veeam Agent computer during live patching.
