Is possible add new netwotk option for VMs to use vhost_net?
for example: -net nic,model=virtio,macaddr=00:16:3e:00:01:01,netdev=nic-0 -netdev tap,id=nic-0,script=/root/ifup-br0,downscript=/root/ifdown-br0,vhost=on
Some articles about it: http://www.linux-kvm.org/page/VhostNet http://www.linux-kvm.com/content/how-maximize-virtio-net-performance-vho...
My test reports rapid increase network preformance between 2 VMs or VM and KVM host. For emaple iperf test: virtio 0.0-10.0 sec 4.38 GBytes 3.76 Gbits/sec virtio + vhost 0.0-10.0 sec 30.9 GBytes 26.5 Gbits/sec
Thank You.
