You have a typo in DEVICE=brWAN with BRIDGING_OqPTS= which seems to have acquired a stray q.

Using DHCP on brWAN is almost certainly going to try to set the default route which is already set in brLAN with GATEWAY=. You can only have one default route.

You've got the same HWADDR= in both NAME=ethWAN and NAME="eth0"

What real device is brLAN meant to be using? It isn't referred to by either of your ifcfg-eth* files.

brWAN --> This connection should be a bridge from internet to VM WAN adapter.
brLAN --> This is meant to be a connection from VM to host and containers

br LAN should be using nought but virtual adapters.

the stray "q" is due to my failure to copy and paste

As for the HW address, this might be because eth0 is enslaved to brWAN
here is how the network adapters are configured in my VM:
