I can see that virtio network performance is poorer than emaulated e1000 nic. I did some simple ping test and with emulated e1000 the average rtt is around 600 microsec. With virtio the average rtt is 800 microsec. I am using a tap + bridge configuration. I run kvm as follows kvm -m 512 -hda vdisk.img \ -net nic,model=virtio \ -net tap,ifname=tap0,script=qemu-ifup,downscript=no I am running Debian squeeze distribution with guest and host kernel 2.6.34. Does anyone else see some results like this or is it only me? Could changing the distribution help as i am running a testing one?
