Hi Parth, Keep in mind you are in unchartered waters – so there may be some stumbling blocks before you get this to work.
I suspect what you have to do is change cloudbr1 such that it is backed by a fake or dummy ethernet interface. What seems to happen is the agent script looks for the network device backing the bridge rather than the bridge itself. This would mean your setup is like this: Physical eth0 -> cloudbr0 > handles management and public Dummy eth1 -> cloudbr1 > handles isolated guest traffic and allows for isolated VLANs internally on the host Keep in mind the context here – you have stated you don’t want VLANs traversing your physical network, hence we are trying to get this working on a single host only. How you configure your IP ranges for management and public is something you need to experiment with and see what works for you.

I have tried several approaches but none seem to work (like creating the bridge through virt-manager GUI or typing the IP configuration of targeted guest network in the cloudbr1 file). Also, the method you suggested here where L2 network does not leave the host, that would basically mean we do not need to have a physical network in our LAN? like I currently have 192.168.20.0/24<http://192.168.20.0/24> and 172.16.20.0/16<http://172.16.20.0/16> in my physical network, but I could possibly create a isolated guest network of 10.0.2.0/24<http://10.0.2.0/24> ? I am also attaching the management-server logs if it would not be stripped by mailing system. The logs of agent had nothing interesting or related to network configuration errors, so not attaching them here.

CloudStack then takes care of creating the isolated VLAN isolated networks on the host. So in short – you create your bridges, then use the bridge names in the advanced zone setup. Virtual bridge – yes this is similar to the cloud0 bridge, and yes you create the bridge without a physical interface.

Sorry if I have missed something obvious or my question seems stupid, but I am just starting to learn. Can you help me out on how to setup VLAN "tagging" on one machine? I have tried several methods and tutorials I could find on the internet for VLANs, but none mention "tagging". Also, I do not fully understand private virtual bridge..... Means I create an interface file for bridge but mention no physical interface device? Is it similar to how cloud0 is configured for link local network of System VMs? I could probably do that, but I don't know much about configuring VLAN tagging. I would appreciate if you could give me some guidance or point me where you think some good documentation is given for CentOS/RHEL hosts for configuring bridges with VLAN tagging (I have tried but failed to understand most of them). I am especially stuck at understanding this "tagging" of VLANs.
