Agenda

  • Namespaces/Containers (8:30am-11am)
    • sysfs issues (and any /proc issues)
      • uevents/hotplug
    • Network namespaces issues
      • multiple namespaces in one process
    • Device namespace design?
    • User namespace
    • Additional needed namespaces
      • Small namespaces What to do with small subsystem that might need virtualization. E.g. in openvz we have FUSE, binfmt_misc and some other small stuff virtualized. But how to merge it in mainline? Create a separate namespace for each? Mere them into one? How to call this then?
    • Handling filesystem/namespace synchronization (not sure what the issue is)
    • Container design
      • How to enter a container
      • Nature of a 'container' — kernel object or userspace fiction
  • Cgroups+Resource management (11:30-2pm)
    • Cgroup implementation
    • Additional cgroups and their design
    • libcg - userspace explotation of control groups/resource management
    • Resource management
  • Checkpoint/Restart (2:30pm-5pm)
    • Summary of existing c/r patchsets/designs
    • How to initiate and synchronize checkpoint/restart
    • (state of freezer subsystem?)
    • Memory state dump
    • How to dump/fetch data for resource (file, ipc) checkpoint
    • How to do restart
    • Hopefully we can make decisions here, and get a bit of a hackfest going during OLS

Moderators

  • Namespaces/containers: Serge Hallyn, Dave Hansen
  • Cgroups and resource management: Paul Menage, Balbir Singh, Dhaval Giani
  • Checkpoint/restart: Daniel Lezcano, Oren Laadan
