[Openstack] Adding an extra compute node

Hi all,

I'm trying to add a second compute node my dev cluster, I've already got
one controller node and one network/compute node running perfectly. I've
installed all of the necessary packages and everything seems to be running
smoothly. However, when I create a private network and subnet, they don't
seem to be applied to the extra node. That is, I can see the extra
interfaces when I run ovs-vsctl show on the network/compute node, but not
on the dedicated compute node. There are GRE tunnels which I assume connect
the two nodes across the management network, and instances boot up on the
new node. They just can't find the internal network and thus can't be
reached at all. I'm running Grizzly on Ubuntu, using Quantum OpenVSwitch
with GRE tunnels. I've already fixed an error regarding brcompatd running
on both nodes,  so I'm wondering what my next step is. Thanks.
