Hi, I''ve two xen-servers (xen2.07) running on Debian, both with two network interface cards in them. This is the configuration of the interfaces in dom0 (/etc/network/interfaces): auto eth0 iface eth0 inet static address 192.168.16.76 netmask 255.255.255.0 network 192.168.16.0 broadcast 192.168.16.255 gateway 192.168.16.77 dns-nameservers 192.168.16.66 dns-search mycompany.com auto eth1 iface eth1 inet static address 192.168.20.251 netmask 255.255.255.0 network 192.168.20.0 broadcast 192.168.20.255 With this configuration, but interfaces are working. I can reach both networks from the xen-server itself, and I can reach both interface from other systems on the network. I have several virtual servers connected to the 192.168.16.* network, all working fine. So far, so good. Today, I started setting up a server which should run in the 192.168.20.* network. From what I have read on the internet, I need to add a bridge for the new network. With the command "/etc/xen/scripts/network start bridge=xen-br1 netdev=eth1", I am able to add the bridge for the 192.168.20.* network. But.. uhoh.. all virtual servers on the 192.168.16.* segment lost their connection. The servers are able to ping 192.168.16.76 (the xen-server itself) but other adresses fail. Same for the virtual server I created in the 192.168.20.* network. (on this server, I added "vif=[ ''bridge=xen-br1'' ]" to the server-config, is that correct?). So, the xen-server itself is still reachable, but the virtual servers running on it are not. Xen-server is able to reach the virtual servers, and the virtual servers are able to reach the xen-server. What am I doing wrong? I can''t find any good documentation on this subject :( Thanks for any help, Kris _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
