[ovirt-users] [Ovirt 4.0.6] Suggestion required for Network Throughput options

[TranceWorldLogic .]

Hi Yaniv,

I have enabled random generator in cluster and also in VM.
But still not see any improvement in throughput.

lsmod | grep -i virtio
virtio_rng             13019  0
virtio_balloon         13834  0
virtio_console         28115  2
virtio_blk             18156  4
virtio_scsi            18361  0
virtio_net             28024  0
virtio_pci             22913  0
virtio_ring            21524  7
virtio_blk,virtio_net,virtio_pci,virtio_rng,virtio_balloon,virtio_console,virtio_scsi
virtio                 15008  7
virtio_blk,virtio_net,virtio_pci,virtio_rng,virtio_balloon,virtio_console,virtio_scsi

Would please check do I missing some virtio module ?

One more finding, if I set queue property in vnic profile then I got good
throughput.

Thanks,
~Rohit
