> When removeNicFromVirtualMachine is called for a nic on an instance the code below is evaluated. This piece of code searches for portforwarding rules across all domains. If another instance exists that has a nic with the same ip and a forwarding rule the search returns >1 and the removeNicFromVirtualMachine call failed.

>         result.addAll(_portForwardingDao.listByDestIpAddr(nic.getIp4Address()));
