10.0.9.5 is probably the ip that nova assigned to your compute host for the bridge.

ip addr show should show it on br100

There is likely something else going on that is causing your instance to fail to network properly. I would check the console output of the vm first, make sure it is getting an ip address. If that looks good, check for security group rules, then start doing tcpdump to see where you are losing packets.
