Two of the main points are size and isolation. The Minix 3 kernel is less than one thousand times the size of Linux. All drivers and the IP stack live in user land. We show a port of the netfilter framework, which leads to a system with better stability and security than the widely used Linux solutions [We07]. Additionally we present some new ideas regarding virtualized systems.enText/Conference Paper1617-5468
