It's still some overhead because it's emulating hardware devices, but thanks to VX, it's not as bad as the classical virtualization trap hacks. Once AMD releases their counterpart version of the virtualization extensions en masse, this will probably get more steam from providers. If a Xen-instrumented kernel is available for the desired OS, that would still be preferable, of course. -- -- Todd Vierling <[email protected]> <[email protected]> <[email protected]>
