Just to be clear, your switches don't need to support VXLAN to utilize it.
The VR will terminate the VXLAN network and translate to a VLAN for your
external traffic.

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.

Hi Imran,

OVS is the same as GRE tunnelling, which you will have as an isolation
method for guest networking - see

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).

    Dear Team,

    I have setup cloudstack 4.9 with KVM hypervisor and advanced networking
    CentOS7. Also we installed and setup openvswitch on the hypervisors

    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
    guest network.

    However OVS is not shown in the list.

    Please suggest what could be wrong here.

    Kind regards,
