Hi guys, we installed a testing environment with cloudstack 4.4.2. In this testing environment we have two centos 6.6 nodes with ovs 2.3.1. Providing a virtual machine with a network service offering based on ovs, we saw an is ovs bridge was automatically configured on kvm nodes but no gre tunnel port was created within it. Reading ovstunnel.log we discovered an error : the gre tunnel was created and immediatelly deleted as you can see in the following ovstunnel.log lines :
