Google Posts New Version Of Live Update Orchestrator For Speedy Kernel Updates In Production Environments
Back in March Google unveiled the Live Update Orchestrator 'LUO' as a new means of live kernel updates for running production systems with a particular emphasis on servers running cloud workloads
Google's main use-case is for allowing Linux servers to receive kernel updates while having minimal disruption to any running virtual machines (VMs). The updated LUO code also now allows preserving file descriptors (FDs), the DebugFS interface is now optional, and various other improvements. Those interested in LUO can find the RFC v2 patch series on the Linux kernel mailing list.
