<div>It seems that my mail client butchered my response to you so that it was hard to see my in-line comments. I thought I would re-post a cleaned-up version:<br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><span style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small; background-color: rgb(255, 255, 255);">> It was discussed several time in the past, last I remember the issue is</span><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><span style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small; background-color: rgb(255, 255, 255);">> mainly with Windows guests,</span><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><span style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small; background-color: rgb(255, 255, 255);">> There are some hints to solve it in this</span><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><span style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small; background-color: rgb(255, 255, 255);">> page:</span><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><span style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small; background-color: rgb(255, 255, 255);">> http://serverfault.com/questions/624690/windows-guest-on-kvm-qemu-suffers-horrible-key-lag</span><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><br style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small;"><span style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: small; background-color: rgb(255, 255, 255);">Yes I saw this too when researching.
