  • There are two teams for the network setting on the KVM hypervisor, and Virtual Machine on KVM hypervisor cannot ping one of the gateways sometimes. Like the below network architecture:
prod1 VM:
prod2 VM:

      Bridge0(prod1 VM)                         Bridge1(prod2 VM)
            |                                       |
   Team0(active-backup)                     Team1(active-backup)
            |                                       |
    -----------------                       ------------------
    |               |                       |                |
