Greetings,
Could someone let me know if current virtio-net supports zero-copy? I
see some discussion here:
http://thread.gmane.org/gmane.comp.emulators.kvm.devel/28061/
(copyless virtio net thoughts) and it looks like the copyless
virtio-net is not supported by KVM yet.
That is correct.
If this is true, then is there
any plan to add the zero copy to the virtio-net?
Yes, but it will be a difficult journey.
I use KVM in 10G network environment and found the CPU usage is
saturated when network traffic becomes heavy. The native Linux under
the same load only consumes less than 10% CPU.
Running the latest guest and host software (both qemu and kernel) will
improve things somewhat.
