Thank you very much for this. Are you using openvswitch for this config?

Use these bridge names as traffic labels in the Physical Network you create during zone creation in CloudStack. Eg. If cloudbr0 is on eth0 and cloudbr1 is on eth1 then use cloudbr0 as traffic lable for guest and public traffic and cloudbr1 for management traffic. Following configuration might help you in configuring bridges: Configure network interfaces: /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none IPV6INIT=no NM_CONTROLLED=no ONBOOT=yes TYPE=OVSPort DEVICETYPE=ovs OVS_BRIDGE=cloudbr0 /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=none IPV6INIT=no NM_CONTROLLED=no ONBOOT=yes TYPE=OVSPort DEVICETYPE=ovs OVS_BRIDGE=cloudbr1 /etc/sysconfig/network-scripts/ifcfg-cloudbr0 DEVICE=cloudbr0 ONBOOT=yes DEVICETYPE=ovs TYPE=OVSBridge BOOTPROTO=static IPADDR=172.16.10.10 GATEWAY=172.16.10.1 NETMASK=255.255.255.0 HOTPLUG=no /etc/sysconfig/network-scripts/ifcfg-cloudbr1 DEVICE=cloudbr1 ONBOOT=yes DEVICETYPE=ovs TYPE=OVSBridge BOOTPROTO=none HOTPLUG=no Thanks, Sanjeev -----Original Message----- From: Jake G.
