freebsd announce - Jul 2010 - Foundation Announces Resource Containers Project

Dear FreeBSD Community,

We are pleased to announce that Edward Tomasz Napierala has been awarded 
a grant to implement resource containers and a simple per-jail resource 
limits mechanism.

Unlike Solaris zones, the current implementation of FreeBSD Jails does 
not provide per-jail resource limits.  As a result, users are often 
forced to replace jails with other virtualization mechanisms.  The goal 
of this project is to create a single, unified framework for controlling
resource utilisation, and to use that framework to implement per-jail 
resource limits.  In the future, the same framework might be used to 
implement more sophisticated resource controls, such as Hierarchical 
Resource Limits, or to implement mechanisms similar to AIX WLM. It could 
also be used to provide precise resource usage accounting for 
administrative or billing purposes.

"It's great that the Foundation decided to fund this project,"
Edward
noted. "It will make jail-based virtualization a much better choice in 
many scenarios, for example for Virtual Private Server providers."

Sincerely,

The FreeBSD Foundation
