'''When''': 22nd of July 2008<br/>
'''Where''': Ottawa, ON, Canada.

== Proposal ==

The mini-summit proposal sent to OLS organizers. '''See [[/Proposal|proposal]]'''.

== Topics to discuss ==

* Device accessibility cgroup (maybe with remap ability)
* TTYs
* Syslog
* Checkpoint/restart
* Memory controllers
* more?..

== List of attendees ==
Please fill in your name here if you are going to attend, or email kir at openvz dot org if you are too lazy. Surely the list is not final, so put your name even if you are not sure you can make it.

== 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?
* 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
