POX doesn't currently support IPv6. (This is mostly because OpenFlow 1.0 only
supports IPv4. IPv6 is being added because Open vSwitch supports it through an
extension and because we're planning to support OpenFlow 1.2. The first
version is almost but not quite complete; it is slated for carp.)
So this is probably at least a major component of your problem. Use IPv4. You
can either statically configure the addresses, or run dhclient or whatever on
your VMs if your OpenFlow network is connected to a DHCP server. If it's not,
you can use POX's DHCP server.
Hope that helps.
