----------------------------------

I found this error starting from the below code.

NetworkManagerImpl.java

NicProfile profile = guru.allocate(network, requested, vm);     (1)
        if (isDefaultNic != null) {
            profile.setDefaultNic(
isDefaultNic);
        }

ExtenalGuestNetworkGuru.java

    @Override
    public NicProfile allocate(Network config, NicProfile nic, VirtualMachineProfile<? extends VirtualMachine> vm) throws InsufficientVirtualNetworkCapcityException,
            InsufficientAddressCapacityException {

        if (_networkModel.networkIsConfiguredForExternalNetworking(config.getDataCenterId(), config.getId()) && nic != null && nic.getRequestedIpv4() != null) {
            throw new CloudRuntimeException("Does not support custom ip allocation at this time: " + nic);
        }
       
        NicProfile profile = super.allocate(config, nic, vm);

        boolean _isEnabled = Boolean.parseBoolean(_configDao.getValue(Config.OvsTunnelNetwork.key()));     (2)
        if (_isEnabled) {
            return null;
        }

        if (_networkModel.networkIsConfiguredForExternalNetworking(config.getDataCenterId(), config.getId())) {
            profile.setStrategy(ReservationStrategy.Start);
            /* We won't clear IP address, because router may set gateway as it IP, and it would be updated properly later */
            //profile.setIp4Address(null);
            profile.setGateway(null);
            profile.setNetmask(null);
        }

        return profile;
    }

The return from (1) is NULL, because at (2) sdn.ovs.controller set to true. So profile = NULL and then we get NullPointerException error in the next step.

This error prevents me to deployVM using GRE isolation method. If I set sdn.ovs.controller = false, no error anymore but can't using GRE.

> I'm trying to use native SDN controller with GRE isolation method. It's tested with XCP 1.6. The purpose is controlling what's happen.
