Xen Live Patching - Updating Xen Without Rebooting - Konrad Wilk, Oracle & Ross Lagerwall, Citrix

Oracle and Citrix have been working together to bring live-patching to the Xen hypervisor. This will allow system administrators to update the hypervisor without the need to reboot. The talk will provide an overview of how it works, what were the difficulties in implementing it, how it compares to the other technologies for patching (uSplice, kSplice, kPatch, kGraft, Linux hot-patching), how to use it, and what is in the roadmap schedule.
