I haven't tried a setup using nova network, but when I attempted a setup
with Neutron in VMWare, I had the same arp issues. When I put everything on
physical hosts except the control node, my issues went away. I don't know
the exact cause of the issue, but it seems to have something to do with the
VMWare virtual switch.
