Hi Si,

I agree. However we had to go for VLAN due to the physical switch
limitations and limited number of VLANs  so far.

I'd strongly suggest you consider using the native VXLAN support for KVM. It
works extremely well and we run it in production.

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,
