Hi, I've currently run into the situation where Xen in bridged mode will only work for IP's on the same subnet as domain0. Routed mode isn't an option as IP's on the same subnet will be in use by other virtual/physical servers. Currently the router is configured to handle about a dozen subnet's and it aliases an IP to it's interface for use as a default gateway for LAN devices. If I configure the xenU's on the same subnet as domain0 things work fine so I am sure the bridge config is correct. To make sure though I did make Xend use my bridge setup that works for my User Mode Linux VM's. 1) Using Linux bridging I am able to accomplish what I want using User Mode Linux. As far as I can tell UML is not doing anything special, the interface options are identical once the interfaces are created. I have tried putting the vif interfaces into promiscuous mode. Why is this possible under UML and not Xen when both use Linux kernel bridging? 2) Does anyone have ideas for possible solutions? I've tried various methods of iptables/nat and proxy_arp setups and have been unable to get this to work. I know I could do a 1-to-1 mapping of external IP's to an internal subnet using nat, but that would be very ugly and not something I think of as a workable solution. Ideally i'd like to continue using bridging. -- Thanks, Matt ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.
