This below output should make things clearer:
[root@kvm1-1 ~]# brctl show
bridge name bridge id STP enabled interfaces
breth0-105 8000.000c293bb945 no eth0.105 <— Guest VLAN
105
vnet0
breth0-106 8000.000c293bb945 no eth0.106 <— Guest VLAN
106
vnet1
vnet4
breth0-64 8000.000c293bb945 no eth0.64 <— Public VLAN

vnet3
cloud0 8000.fe00a9fe038c no vnet2
cloudbr0 8000.000c293bb945 no eth0
virbr0 8000.525400ad416c yes virbr0-nic
[root@kvm1-1 ~]# virsh list

----------------------------------------------------
1 i-3-5-VM running
2 r-7-VM running
3 i-2-6-VM running
breth0-“vlanid" is automatically created by CloudStack for guest
and public traffic. cloudbr0 is the only bridge interface created
that I had to manually create before adding the host to CloudStack.
