Are there any plans to enhance virtio_net with receive-side scaling capabilities, so that an SMP guest OS can balance its network processing load more equally across multiple CPUs?
Thanks,
Anna

Yes, the MSI-X patches are the first steps towards this. We will enable
each queue to have its own interrupt; then we can have a queue pair for

Do not meddle in the internals of kernels, for they are subtle and quick to panic.
