Hello, I''m new to Xen (and this mailing-list) and facing some problems with the network. I''m stuck and don''t know how to continue. And Google isn''t very helpful either... My setup: - Ubuntu 7.10 for dom0 and Debian 4.0 for all domU - 4 physical NIC (DHCP from my ISP, internal LAN, DMZ & WLAN) - 1 Dom as firewall/router - 1 domU with internal services (DHCP-, LDAP-, SAMBA-, ... Server) - 1 domU in DMZ as Webserver My plan: - xenbr0 where eth0 is in it and all my internal domX - xenbr1 where eth1 is in it and all my DMZ domX - xenbr2 where eth2 is in it (WLAN Access Point attached) - xenbr3 where eth0, eth1, eth2 and eth3 for the firewall What I have so far: - Xen installed and dom0 running - xenbr0, xenbr1, xenbr2 and xenbr3 created via custom script: #!/bin/sh dir=$(dirname "$0") "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 "$dir/network-bridge" "$@" vifnum=1 netdev=eth1 bridge=xenbr1 "$dir/network-bridge" "$@" vifnum=2 netdev=eth2 bridge=xenbr2 "$dir/network-bridge" "$@" vifnum=3 netdev=eth3 bridge=xenbr3 - dom1 with eth0 in it for testing with an internal machine - dom2 with eth0-eth3 for the router/firewall (Both of them I start manually) My problems: - When I reboot dom0, I get eth4 instead of eth0, eth5 instead of eth1 and eth6 instead of eth2. The bridges are created but no interfaces are attached of course. I then have to put eth4''s mac-address to eth0, etc. and reboot again, to get eth0 - eth3 and the bridges. It never change eth3''s mac-address (where my cable-modem is attached to). What did I do wrong that I have this behavior? Or is this ''as designed''? My questions: - What''s the configuration for /etc/network/interfaces in dom0? So far I have a fixed IP for eth0-eth2 and DHCP for eth3. Is this correct? - Where do I have to configure DHCP? On eth3 in dom0, on xenbr3 or on eth3 in domU of the firewall? - Do I need to have the real Mac-Address on the physical eth0-eth3 and Xen moves them to the right places or do I need to put em in the vif- statement of each domU? - Do the bridges need to have an IP-Address? - What would be the best approached for remote accessing dom0? Through an internal domX? Uff, so many questions... Thank you in advance for your tips and your help!
