XtreemOS aims to build and promote a Linux based operating system to provide native Virtual Organization (VO) support in the next generation Grids. XtreemOS takes a different approach from many existing Grid middleware by: first, recognizing the fundamental role of VO in Grid computing and hence taking VO support into account from the very beginning of our design; and, second, getting around the overheads brought by layers of existing Grid middleware by enabling native VO support in the Linux operating system. This paper presents our vision of VOs in a Grid operating system and describes various aspects of VO management in our system architecture, ranging from lifecycle management, application execution management, security, to node-level enforcement mechanisms in operating system.
