Yesterday I had 2 VMs running, one was F12 (KDE) and one Ubuntu 9.10. I was in the process of updating my F12 VM. After a few minutes the system started to degrade. By degrade I mean the mouse would be slow to move, screen redraws would take up to a minute, moving from one virtual dektop to another would take up to one minute, etc. When I tried to switch from one VM to the other the system started to really degrade, the disk light was on solid and it was impossible to do anything. At one point the clock on my desktop showed 4:00 PM while my watch showed 4:07 PM. This system degradation went on for at least 20 minutes at which point I gave up and power cycled my laptop. I have noticed that whenever I run a VM the system starts to degrade, part of the problem is due to disk access, but I have also noticed that both processors spend 75 - 90% of the time in wait state. In my case part of the problem maybe that all my VMs are on an external USB drive.
