If you had 3xQuad port network controllers having a total of 12 usable ports, your network bonding+bridging could look as below:
On CentOS/RedHat, the network settings would be as below:
ifcfg-ethN
DEVICE=ethN ONBOOT=yes HOTPLUG=no BOOTPROTO=none TYPE=Ethernet MASTER=bondN SLAVE=yes NM_CONTROLLED=no
ifcfg-bondN
DEVICE=bondN ONBOOT=yes BOOTPROTO=none USERCTL=no NM_CONTROLLED=no TYPE=Ethernet BRIDGE=cloudbrN BONDING_OPTS="mode=4 miimon=100"
ifcfg-cloudbrN
DEVICE=cloudbrN
TYPE=Bridge
ONBOOT=yes
STP=yes
BOOTPROTO=static
USERCTL=no
NM_CONTROLLED=no
DELAY=0
# XXX: IP Address assignments are required only for Management and
# Storage traffic. Guest/Public bridges don't have IP Assignments
IPADDR=${ipaddress}
PREFIX=${prefix}
GATEWAY=${gateway}
Depending on your requirements and switch support, you could change bonding mode to better suit your requirements. Please refer RedHat Manual for available options.

can you provide a bond mode 0 (balance-rr) configuration for ubuntu 14.04 with kvm and cloudstack . I am facing an issue with this setup as , the hosts are attaching and system vms are creating in cloudstack . But the agent not showing as running for systemvms and the ssvm health check script showing that it is unable to ping management node .
Note : No traffic seggregation using Vlans . Only primary storage is connecting using private IP which is RBD . And this configuration is working perfectly with bond mode 6 ie adaptive load balancing mode .
