I followed Pasi's setup at http://wiki.xensource.com/xenwiki/RHEL6Xen4Tutorial to configure and a SL6 box. This all worked great and I have a working system. When I look at my bridge with 'brctl show' I am seeing this as the output: brctl show bridge name bridge id STP enabled interfaces xenbr5 /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory /sys/class/net/xenbr5/bridge: No such file or directory 8000.001125a5ce44 no bond0.5 The files are in the system as 'ls -l' shows: ls -l /sys/class/net/xenbr5/bridge/ total 0 -rw-r--r-- 1 root root 4096 Apr 3 11:23 ageing_time -r--r--r-- 1 root root 4096 Apr 3 11:23 bridge_id --w------- 1 root root 4096 Apr 3 11:29 flush -rw-r--r-- 1 root root 4096 Apr 3 11:23 forward_delay -r--r--r-- 1 root root 4096 Apr 3 11:23 gc_timer -rw-r--r-- 1 root root 4096 Apr 3 11:29 group_addr -rw-r--r-- 1 root root 4096 Apr 3 11:23 hello_time -r--r--r-- 1 root root 4096 Apr 3 11:23 hello_timer -rw-r--r-- 1 root root 4096 Apr 3 11:23 max_age -rw-r--r-- 1 root root 4096 Apr 3 11:29 priority -r--r--r-- 1 root root 4096 Apr 3 11:23 root_id -r--r--r-- 1 root root 4096 Apr 3 11:23 root_path_cost -r--r--r-- 1 root root 4096 Apr 3 11:23 root_port -rw-r--r-- 1 root root 4096 Apr 3 11:23 stp_state -r--r--r-- 1 root root 4096 Apr 3 11:23 tcn_timer -r--r--r-- 1 root root 4096 Apr 3 11:23 topology_change -r--r--r-- 1 root root 4096 Apr 3 11:23 topology_change_detected -r--r--r-- 1 root root 4096 Apr 3 11:23 topology_change_timer I am bonding my interface eth0 and eth1 and assinging the bridge to the bond, here are my ifcfg scripts: # Intel Corporation 82546GB Gigabit Ethernet Controller DEVICE=eth0 HWADDR=00:11:25:a5:ce:44 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes ISALIAS=no MTU=9000 NM_CONTROLLED=no # Intel Corporation 82546GB Gigabit Ethernet Controller DEVICE=eth1 HWADDR=00:11:25:a5:ce:45 BOOTPROTO=none ONBOOT=yes MASTER=bond0 SLAVE=yes ISALIAS=no MTU=9000 NM_CONTROLLED=no DEVICE=bond0 BOOTPROTO=none BONDING_OPTS="mode=1 miimon=100" ONBOOT=yes MTU=9000 NM_CONTROLLED=no DEVICE=bond0.5 BOOTPROTO=none ONBOOT=yes VLAN=yes BRIDGE=xenbr5 TYPE=Ethernet MTU=9000 NM_CONTROLLED=no DEVICE=xenbr5 BOOTPROTO=static IPADDR=192.168.6.2 NETMASK=255.255.255.0 BROADCAST=192.168.6.255 ONBOOT=yes TYPE=Bridge MTU=9000 NM_CONTROLLED=no I read through this post, http://permalink.gmane.org/gmane.comp.emulators.xen.devel/98821, and it never did give an answer to what may be causing this. Is this something that can be ignored? Thanks for any help, Jon -- xen mailing list xen@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/xen
