I was thinking about this over the weekend, and it occured to me that this might not be the case. Today, when we are all doing testing on xen-unstable, we're pretty much always running test domUs so have something like: ethX -> bridged/routed to domUs ethY -> dom0 only, in case ethX dies However, in many production environment you need an administrative lan to all servers to apply software updates and the like. So you'd actually have. ethX -> bridged/routed production lan for domUs ethY -> bridged/routed admin lan for domUs Hopefully ethY would be reliable enough that we wouldn't need a 3rd NIC to be admin for dom0 in the event of xen network stack fall over, but we might. Not proposing any solutions as yet, but it is worth noting that this might not be as uncommon as first thought. -Sean -- __________________________________________________________________ Sean Dague Mid-Hudson Valley sean at dague dot net Linux Users Group http://dague.net http://mhvlug.org There is no silver bullet.
