- ホスト側のvethデバイス名を指定する
- lxc-chroot-linux-containers - Re: (Lxc-users) veth name - msg#00058 - Recent Discussion OSDir.com
- man 5 lxc.conf
By default lxc choose a name for the network device belonging to the outside of the container, this name is handled by lxc, but if you wish to handle this name yourself, you can tell lxc to set a specific name with the lxc.network.veth.pair option.
- 複数のコンテナで同じ名前のpairを指定すると、二つ目は起動しない(下記の例ではtest1, test2コンテナでlxc.network.veth.pair = testと指定)
- $ sudo lxc-start -n test2
lxc-start: failed to create test-vethNdql6o : File exists lxc-start: failed to create netdev lxc-start: failed to create the network lxc-start: failed to spawn 'test2' lxc-start: No such file or directory - failed to remove cgroup '/sys/fs/cgroup/cpu/sysdefault/lxc/test2'
- 指定しない場合、mktemp("vethXXXXXX")で決定される
- SourceForge - lxc/lxc/blob - src/lxc/conf.c
static int instanciate_veth(struct lxc_handler *handler, struct lxc_netdev *netdev)
- ホスト側の物理NIC(lxc.network.link)とリンクするveth1の名前やifindexを外部から知る手段が無い模様

- Debian Squeezeと異なり、Ubuntu 12.04ではlxc-cgroup -t container_name tasksが使えない
- https://www.kernel.org/doc/Documentation/cgroups/cgroups.txt
Each cgroup is represented by a directory in the cgroup file system containing the following files describing that cgroup:
- tasks: list of tasks (by pid) attached to that cgroup. This list is not guaranteed to be sorted. Writing a thread id into this file moves the thread into this cgroup.
- cgroup.procs: list of tgids in the cgroup. This list is not guaranteed to be sorted or free of duplicate tgids, and userspace should sort/uniquify the list if this property is required. Writing a thread group id into this file moves all threads in that group into this cgroup.
- notify_on_release flag: run the release agent on exit?
- release_agent: the path to use for release notifications (this file exists in the top cgroup only)
- まとめ
- lxc-cgroupコマンドを使わない場合、以下のsysfsにアクセスすると良い模様
