I actually think the containers and Xen complement each other very well. As Xen is now based on 2.6.16 (as are both VServer and OVZ) it makes sense to run a few Xen domains that then in turn run containers in some scenarios. As far as the last part, Xen doesn't share resources at all :) Thank you, Matt Ayres - 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/
