> 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.

> @Override
> public List<FirewallRuleVO> listAssociatedRulesForGuestNic(Nic nic){
> List<FirewallRuleVO> result = new ArrayList<FirewallRuleVO>();
> // add PF rules
>
> result.addAll(_portForwardingDao.listByDestIpAddr(nic.getIp4Address()));
> // add static NAT rules
