[lxc-devel] LXC 1.0 and feature support on kernel level

[Jäkel, Guido]

Dear Core-Developers,

i would like to ask for a discussion about the status of a kind of improvements that -- as I know -- will need support by the kernel developers. But a LXC (newbie) user may expect such things from a software level 1.0, will miss it. In the worst case, this may have impacts on the image of LXC because one may think it's in the direct concern of LXC to provide it.

As an example, the cgroups framework offers the (functional) resource limiters for memory and CPU. But for a process within such a group -- here: a container -- there's no adequate projection on the common used interfaces by all the software around: It will determine the memory resources or total number of CPUs of the host. Therefore the user have manually adjust it - if he knows about the fact and the software offer the possibility to override it.

Is there any ongoing work on this by kernel developers? May there be notable improvements within the timeline of the LXC 1.0 release?


with greetings

Guido
