(I suppose, it is also relavant to > mention that I plan to use ECMP to balance the incoming requests > amongs the LVS instances), LVS is quite basic in the way it works. If your request is not present in the table, it will be scheduled to some real server. Otherwise, the request is forwarded to the real server recorded in the table. The TCP state of the connection is unimportant. What you want to do will just work without syncing states (you need to use DR as the load balancing kind) and this is a documented setup: http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.localnode.html Syncing states will break the setup as 127.0.0.1 on server A is not the same than 127.0.0.1 on server B, so a state on server A cannot be used by server B. -- Use free-form input when possible. - The Elements of Programming Style (Kernighan & Plauger) ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
