Hi there,<div><br></div><div>I'm currently using xen for various experiments (as it's much easier and cheaper than running two or three linux boxes).</div><div>As I tend to use Xen frequently I usually boot directly into it even when I don't actually fire up any VMs.</div>
<div><br></div><div>I was wondering what's the difference in performance between linux running in dom0 and no VMs (domUs) running compared to native linux.</div><div>Obviously if you use something like virtualbox when there are no VMs running you just have linux running natively so you have no performance penalties.</div>
<div>Is it the same if you're running Xen with no hosts?</div><div><br></div><div>Does it affect the way linux runs in any way?</div><div><br></div><div>Thanks for your help</div><div>Nahuel</div>
