You won't be able to ping the nodes from the controller since it has no ip address on the guest network.
It looks like eth1 is bridged in properly on the compute node you showed, although I don't see it showing up in the interface list. It looks like maybe eth1 is not up? Try: ifconfig eth1 up you should be able to ping from 10.10.10.3 - 10.10.10.4 if your eth1s are up and plugged in and your switch isn't filtering traffic.
