When we did this in VMware or in Hyper-V we didn't have these issues, and I have seen other KVMs that were running good as well. So I was thinking it could have something to do with the disk images to do, there is nothing to see on the CPU, Memory, Network or the physical discs and I have tried to run vmstat and iostat from within the machines will this issue was seen but not iowaits. I will do some more testing and let you know thank you.
