vxlan code. Users can set a physical network to isolation type 'vxlan',
put public traffic on that physical network, and it will still attempt
to use 'vlan' isolation on the KVM hosts. This is going to be an issue
for other isolation types as well, but I'm not familiar with them, so
I'm just fixing vxlan for now.
Those bugs are related to classes not implementing Serializable, nox overriding the equals and/or hashCode methods and with empty finalize method.
