This is more like it. Working in conjunction with Solaris's zones you can now specify a virtual NIC that has configurable bandwidth
and you can configure a virtual network complete with connections, switches etc. that has QoS, prioritisation etc all on the one box. If Sun were hoping to create a market for big-arse boxes this might be a good way to do it.
So a zone can now have memory quotas, cpu quotas, network bandwidth quotas, can be moved from one physical machine to another and use ZFS as a storage pool. I bet you could make an
astounding virtualisation platform out of this...
