    Enable Multi-Queue Support for NICs on KVM

    Modify the guest XML definition to enable multi-queue virtio-net. Multi-queue virtio-net allows network performance to scale with the number of vCPUs and allows for parallel packet processing by creating multiple TX and RX queues.
    1. Modify the guest XML definition. Insert a value from 1 to 256 for N to specify the number of queues. For the best results, match the number of queues with number of dataplane cores configured on the VM.
      <interface type='network'> 
      <source network='default'/> 
      <model type='virtio'/> 
      <driver name='vhost' queues='N'/> 
</interface>
