[Xen-users] 1 host, 1 nick, 1 regular bridge, 1 local bridge, 5 vm
So Working on CEntOS 5 I am trying to sett up Xen with 2 bridges, one that connects dom0 and most of the domU to the physical card and the out to the network. Got that figured out no problem, now i want to have a second bridge that runs a local network for all the doms that doesn''t connect to the network. With code I have found used in multiple places I can easily get 2 bridges, and have all the Domu connected to it but i can''t get Dom 0 to have an interface. Script to set up bridges called fine from xend-config.sxp ]# cat multiple-bridge> #!/bin/sh > dir=$(dirname "$0") > "$dir/network-bridge" "$@" vifnum=0 netdev=eth0 bridge=xenbr0 > "$dir/network-bridge" "$@" vifnum=2 netdev=dummy bridge=xenbrloc1Out put from brctl show> bridge name bridge id STP enabled interfaces > xenbr0 8000.feffffffffff no vif1.0 > > peth0 > > vif0.0 > xenbrloc1 8000.feffffffffff no vif2.0 > > vif1.1Output of ifconfig eth0 Link encap:Ethernet HWaddr 48:5B:39:17:09:73 inet addr:192.168.1.119 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::4a5b:39ff:fe17:973/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:392 errors:0 dropped:0 overruns:0 frame:0 TX packets:363 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:104964 (102.5 KiB) TX bytes:50630 (49.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:140044 errors:0 dropped:0 overruns:0 frame:0 TX packets:140044 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:87780902 (83.7 MiB) TX bytes:87780902 (83.7 MiB) peth0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:311531 errors:0 dropped:0 overruns:0 frame:0 TX packets:46014 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:73445358 (70.0 MiB) TX bytes:5556591 (5.2 MiB) Interrupt:16 Base address:0xe000 vif0.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:40325 errors:0 dropped:0 overruns:0 frame:0 TX packets:299826 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5015081 (4.7 MiB) TX bytes:54011703 (51.5 MiB) vif1.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:9152 errors:0 dropped:0 overruns:0 frame:0 TX packets:16963 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:32 RX bytes:1064334 (1.0 MiB) TX bytes:20750937 (19.7 MiB) vif1.1 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:13 errors:0 dropped:0 overruns:0 frame:0 TX packets:13 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:32 RX bytes:580 (580.0 b) TX bytes:762 (762.0 b) vif2.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:13 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:32 RX bytes:580 (580.0 b) TX bytes:0 (0.0 b) xenbrloc1 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:26 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1160 (1.1 KiB) TX bytes:0 (0.0 b) xenbr0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF UP BROADCAST RUNNING NOARP MTU:1500 Metric:1 RX packets:268045 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:46171788 (44.0 MiB) TX bytes:0 (0.0 b) Any help or guidance would be appreciated John _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Is this Debian ? If so then you can put something like this in /etc/network/interfaces - check the syntax, I''m typing this from memory : auto xenbrloc1 xenbrloc1 inet static ip address a.b.c.d netmask w.x.y.z pre-up brctl addbr xenbrloc1 post-down brctl delbr xenbrloc1 I think this should work for you. What happens is that when the I/F is brought up, the bridge is created first (pre-up), and then the IP addr is added to it. The bridge is automatically deleted if the I/F is taken down. For other distros you''ll need to adapt as required. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.

interface(bridge dummy).
Load kernel module.

pre-up ifconfig $IFACE up
post-down ifconfig $IFACE down
auto lan-xen-ofi
iface lan-xen-ofi inet manual
