Hi, Based on the documentation found at http://docs.openstack.org/folsom/openstack-compute/install/yum/content/compute-configuring-guest-network.html
I have the following network configuration where em1 is my interface to the internet and em2 is the nic that connects to network that I want to create virtual machines on but a couple of things are concerning me 1. br100 has a state UNKNOWN. I believe it should have a state of UP, is this correct ? # ip a | grep state 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 3: em2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 4: br100: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 5: virbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 6: virbr0-nic: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 500 2. I am seeing entries in /var/log/messages that seem to indicate the bridge is being disabled Jul 31 14:55:56 prancer kernel: br100: port 1(em2) entering forwarding state Jul 31 14:57:35 prancer kernel: br100: port 1(em2) entering disabled state Can anyone spot what I have done wrong ? # cat /etc/sysconfig/network-scripts/ifcfg-em1 DEVICE="em1" BOOTPROTO="dhcp" HWADDR="00:24:E8:FE:0E:8A" IPV6INIT="no" MTU="1500" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" UUID="21202849-7fc3-4ff6-a1ab-182f39c0cb61" # cat /etc/sysconfig/network-scripts/ifcfg-em2 DEVICE="em2" HWADDR="00:24:E8:FE:0E:8B" IPV6INIT="no" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" UUID="60907d22-f71a-4f9f-b6e0-1f1487196b65" IPADDR=192.168.206.130 NETMASK=255.255.255.0 PROMISC=yes # cat /etc/sysconfig/network-scripts/ifcfg-br100 DEVICE=br100 TYPE=Bridge BOOTPROTO=none IPADDR=192.168.100.1 NETMASK=255.255.255.0 ONBOOT=yes DELAY=0 # brctl show br100 bridge name bridge id STP enabled interfaces br100 8000.0024e8fe0e8b no em2 # brctl showmacs br100 port no mac addr is local? ageing timer 1 00:24:e8:fe:0e:8b yes 0.00 All nova services appear to be running with the config as it is # nova-manage service list Binary Host Zone Status State Updated_At nova-volume prancer nova enabled :-) 2013-07-31 04:22:00 nova-scheduler prancer nova enabled :-) 2013-07-31 04:21:59 nova-cert prancer nova enabled :-) 2013-07-31 04:21:53 nova-compute prancer nova enabled :-) 2013-07-31 04:21:57 nova-network prancer nova enabled :-) 2013-07-31 04:21:53 nova-console prancer nova enabled :-) 2013-07-31 04:21:53 nova-consoleauth prancer nova enabled :-) 2013-07-31 04:21:59 Thanks
