Hello Michael, Some initial vhost test netperf results on my T61 laptop from the working tap device are here, latency has been significant decreased, but throughput from guest to host has huge regression. I also hit guest skb_xmit panic. netperf TCP_STREAM, default setup, 60 secs run guest->host drops from 3XXXMb/s to 1XXXMb/s (regression) host->guest increases from 3XXXMb/s to 4XXXXMb/s TCP_RR, 60 secs run (very impressive) guest->host trans/s increases from 2XXX/s to 13XXX/s host->guest trans/s increases from 2XXX/s to 13XXX/s Thanks Shirley -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
