I'd like to put a theory out there: the more isolation we perform, the easier checkpointing and migration become to guarantee. Agree? Disagree? But, full isolation is hard to code. The right approach is very likely somewhere in the middle where we require some things to happen underneath us. For instance, requiring that the filesystem be made consistent if a container is moved across systems. -- Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
