I need some guidance setting up an OVS/KVM/ACS node in my lab. I have also pinged the OVS guys, but I thought it wouldn't hurt to ask here as well. I am running into issues getting things to talk properly. With my below configuration, everything starts up correctly with IP addresses and such, however, I can't talk across the network. Been working on this all day and I figure getting a different set of eyes on it might do some good.
The environment is CentOS 6.4 with OVS 1.9 and ACS 4.1 I have 2 10gbe interfaces eth2 and eth4 setup for a bond, and that bond goes to a real OVS switch, and from there I have 3 fake switches. Everything is done through /etc/sysconfig/network-scripts/ifcfg-* bond0 = eth2 eth4 br0 = real bridge mgmtbr0 = fake bridge for management network, VLAN 100 sanbr0 = fake bridge for SAN network, VLAN 1000 cloudbr0 = fake bridge for VM guest networks, VLAN 0 (Utilizing CloudStack, it will automatically talk to OVS to create guest networks off of this network. Correct me if I am wrong, but I think this is the best way to do that. I don't want this bridge to have a VLAN because CloudStack will use this bridge to place it's networks (it creates ports off of the bridge iirc), if it had a VLAN such as 101, I would be afraid I would end up getting Q in Q, and I do not want that) Here are my configuration scripts: bond0 DEVICE="bond0" BOOTPROTO="none" ONBOOT="yes" NM_CONTROLLED="no" HOTPLUG="no" MTU="9000" DEVICETYPE="ovs" TYPE="OVSBond" OVS_BRIDGE="br0" BOND_IFACES="eth2 eth4" OVS_OPTIONS="bond_mode=active-backup lacp=off vlan_mode=trunk other_config:bond-detect-mode=miimon other_config:bond-miimon-interval=100" br0 DEVICE="br0" ONBOOT="yes" NM_CONTROLLED="no" HOTPLUG="no" DEVICETYPE="ovs" TYPE="OVSBridge" BOOTPROTO="static" STP="off" MTU="9000" OVS_EXTRA="br-set-external-id $DEVICE bridge-id $DEVICE" mgmtbr0 DEVICE="mgmtbr0" ONBOOT="yes" NM_CONTROLLED="no" BOOTPROTO="static" TYPE="OVSBridge" DEVICETYPE="ovs" HOTPLUG="no" MTU="9000" STP="off" OVS_EXTRA="br-set-external-id $DEVICE bridge-id $DEVICE" OVS_OPTIONS="br0 100" IPADDR="X.X.X.X" NETMASK="255.255.255.0" sanbr0 DEVICE="sanbr0" ONBOOT="yes" NM_CONTROLLED="no" BOOTPROTO="static" TYPE="OVSBridge" DEVICETYPE="ovs" HOTPLUG="no" MTU="9000" STP="off" OVS_EXTRA="br-set-external-id $DEVICE bridge-id $DEVICE" OVS_OPTIONS="br0 1000" IPADDR="X.X.X.X" NETMASK="255.255.255.0" cloudbr0 DEVICE="cloudbr0" ONBOOT="yes" NM_CONTROLLED="no" BOOTPROTO="static" TYPE="OVSBridge" DEVICETYPE="ovs" HOTPLUG="no" MTU="9000" STP="off" OVS_EXTRA="br-set-external-id $DEVICE bridge-id $DEVICE" OVS_OPTIONS="br0 0" Thanks for taking a look!
