I am trying to use Xen to consolidate my development server (OpenSolaris 2009.06) as a PV domain onto my desktop machine (OpenSolaris b130), however I've noticed that when I boot under Xen, my desktop becomes more sluggish. For example, Firefox scrolls slower and audio playback skips and stutters every few seconds. That's with no domUs running; it's even worse when I start a domU, even if it's idle.
My desktop machine is a Sun Ultra 24 with a Core 2 Quad processor and 4 GB of memory, so I can't imagine hardware is a limitation. I do notice that while 'top' might report 10% CPU utilization, 'xm top' will show closer to 70 or 80% CPU utilization in the dom0. I'm not sure how to explain that disparity. I realize this may be an unusual use case, but does anyone have any tips for running Xen on a desktop? Are there any tuning parameters that can be tweaked?
