Do you use OpenvSwitch? Do you have arp cache poisoning prevention
enabled? See /var/lib/one/remotes/vnm/OpenNebulaNetwork.conf. If so,
OpenvSwitch prevents ARP on interfaces other than the one it has
OpenFlow rules configured for. See "ovs-ofctl add-flow" logging in oned
log to check what ip's have been configured on what interface(s) and/or
check "ovs-ofctl dump-flows bridge_name" on the hypervisor.

Gr. Stefan
