I do this in my clusters (using six NICs, but that doesn't matter). I've
documented how I create bonds and bridges with details here:
https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial#Network
Scroll down a bit to:
https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial#Configuring_The_Bridge
and
https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial#Network
In short;
- Put the host's IP on the bridge, not the bond.
- HWADDR are defined in the interfaces only, not the bond or bridge.
