Hi Kirill, I've honestly lost track of these discussions along the way, so I hope you don't mind summarizing a bit. Do these patches help with accounting for anything other than memory? Will we need new user/kernel interfaces for cpu, i/o bandwidth, etc...? Have you given any thought to the possibility that a task might need to move between accounting contexts? That has certainly been a "requirement" pushed on to CKRM for a long time, and the need goes something like this: 1. A system runs a web server, which services several virtual domains 2. that web server receives a request for foo.com 3. the web server switches into foo.com's accounting context 4. the web server reads things from disk, allocates some memory, and makes a database request. 5. the database receives the request, and switches into foo.com's accounting context, and charges foo.com for its resource use etc... So, the goal is to run _one_ copy of an application on a system, but account for its resources in a much more fine-grained way than at the application level. I think we can probably use beancounters for this, if we do not worry about migrating _existing_ charges when we change accounting context.
