Agenda
- Namespaces/Containers
- 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?
- Nature of a 'container' — kernel object or userspace fiction
- Handling of /proc and /sysfs within containers
- Handling filesystem/namespace synchronization (not sure what the issue is)
- How to enter a container
- User namespaces?
- Additional needed namespaces
- Cgroups+Resource management
- Cgroup implementation
- Additional cgroups and their design
- libcg - userspace explotation of control groups/resource management
- Resource management
- Checkpoint/Restart
- 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
