Hi Dag, Thank you for your response. I was consulting that documentation link as well. As the documentation says, after selecting the GRE isolation type for guest network, we have to enable the OVS plugin under the service providers list inside cloudstack UI. I could not somehow find OVS in that list.
But anyway we have switched to VLAN isolation mode and using default Linux bridging as they underlying networking provider now. I personally liked to go for VXLAN but the physical switches had a limitation so we had no option but go for VLAN. Currently this solution will support not more than 100 vlans so that’s considerable for now.

Please let us know how you get on – especially how your hypervisor nodes cope with CPU load once the GRE tunnels start growing in numbers (historically this has not scaled well).

Also we installed and setup openvswitch on the hypervisors (KVM) hosts. Below are traffic labels for kvm Cloudbr0 for management Cloudbr1 for guest Cloudbr2 for public After configuring the zone, pod , cluster, host, primary and secondary storages we wanted to enable the OVS plugin under service providers for the guest network. However OVS is not shown in the list. Please suggest what could be wrong here.
