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
Are you sure it's being used? What is the qemu command line (do you see the
device in the guest?)
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.
Interesting - I had assumed the bottleneck would be the
encryption/decryption process, not the network. What do you set exactly?
Does it matter in non-encrypted traffic as well? Are the packets (and the
whole communication) large or small (i.e, would jumbo frames help) ?
Y.
Thanks,
~Rohit
