LinuxWorld / Resource Management

I’m finally back from the LinuxWorld San Francisco. The event was great — I met a lot of interesting people, distributed about hundred of OpenVZ DVDs, saw that Motorola Linux-powered phone, and even won a Slashdot Beanbag! The only disappointing fact is OpenVZ has no booth of its own, so nobody saw OpenVZ was there.

But while I was having fun, our guys did a great job posting sets of User Beancounter (UBC) patches and the network namespaces patches for a review. It looks like UBC stuff caused quite a long discussion. Some valid concerns were raised (and will be addressed).

The other thing is, besides UBC, there is also CKRM (Class-based Kernel Resource Management) out there, which basically has the same (or perhaps broader) goals. As Alan Cox puts it, “[...] OpenVZ has all the controls and resource managers we need, while CKRM is still more research-ish. I find the OpenVZ code much clearer, cleaner and complete at the moment, although also much more conservative in its approach to solving problems”.

That’s right — CKRM is a complex framework for doing resource management, providing an interface to plug specific resource controllers. Framework is here, but there are not too many controllers available (and CKRM is here for a few years already). User beancounters, on the other hand, just do what they were designed for — i. e. to limit a container within its boundaries, not letting it to abuse some kernel resources and thus make troubles for other containers.
