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 
each vcpu.

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