Public bug reported: Please consider setting:
CONFIG_KEXEC_HANDOVER=y CONFIG_LIVEUPDATE=y KHO and LUO are new features available on amd64/arm64 that allow seleced runtime state to survive a kexec reboot, added in v6.19. One of the main use cases is letting VMMs quickly resume guests by having their memory transition from one kernel to the next, but there are many others planned, so enable the features at build time. The feature is disabled at runtime by default unless the cmdline kho=on is specified, so risk for general purpose usage should be very minimal. https://docs.kernel.org/next/core-api/kho/index.html https://docs.kernel.org/next/core-api/liveupdate.html ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: linux-kvm (Ubuntu) Importance: Undecided Status: New ** Affects: linux-meta-azure (Ubuntu) Importance: Undecided Status: New ** Affects: linux-meta-kvm (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Resolute) Importance: Undecided Status: New ** Affects: linux-kvm (Ubuntu Resolute) Importance: Undecided Status: New ** Affects: linux-meta-azure (Ubuntu Resolute) Importance: Undecided Status: New ** Affects: linux-meta-kvm (Ubuntu Resolute) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Resolute) Importance: Undecided Status: New ** Also affects: linux-kvm (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-meta-azure (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-meta-kvm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2143831 Title: linux-*: please enable CONFIG_KEXEC_HANDOVER and CONFIG_LIVEUPDATE To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2143831/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
