[Openstack] Neutron with packstack on several CentOS 6.4 nodes

I am in the process of setting up a cluster of 4 CentOS 6.4
servers, with Neutron and VLAN. The current goal is to create
under the same tenant 3 subnets in different VLANs. Also, I've used
the following guides to do this:
I have tried alternative setups:
A. All services (including compute) on one host + 3 additional compute
B. All services (except compute) on one host + 3 additional compute hosts.
In case A, the guest VM is by default launched on the same host that
runs the rest of the services -- then the VM is reachable.
In case B, the VM is started on one of the compute hosts -- and then the
VMs are not reachable (though running on the compute nodes and viewable
through the instance console) e.g.:
ip netns exec qrouter-b702c4e9-cb3a-4156-8412-f902363075f2 ping 10.0.103.5
PING 10.0.103.5 (10.0.103.5) 56(84) bytes of data.
>From 10.0.103.1 icmp_seq=2 Destination Host Unreachable
>From 10.0.103.1 icmp_seq=3 Destination Host Unreachable
>From 10.0.103.1 icmp_seq=4 Destination Host Unreachable
I've double checked the security group and rules (to allow ssh and icmp).
Logs don't show anything interesting.
* Do the compute hosts need any additional services set up (except the
quantum-openvswitch-agent and openswitch)?
* Could you suggest any troubleshooting tips/techniques?
