Livepatch Visibility at Scale

Explore the challenges and solutions for managing Linux kernel versions and livepatches in hyperscale data centers during this conference talk from the Linux Plumbers Conference. Learn how Meta uses netconsole to analyze console outputs from millions of servers and discover recent improvements that added kernel version information to netconsole messages. Examine the limitations of current approaches when dealing with livepatches and consider proposed solutions for including livepatch information in netconsole and other data sources. Gain insights into the complexities of maintaining visibility and tracking kernel versions across massive server deployments, especially when multiple livepatches are involved.
