As for a laptop example, I just acquired a Dell Latitude E6500 with a Core 2 Duo T9550 @ 2.66GHz. The link for Core 2 Duo is: http://www.intel.com/products/processor_number/chart/core2duo.htm?iid=pn_ov+list_c2d which shows it has VT capability (which of course I confirmed before ordering this laptop). > > The header before each chart lists which processors have VT-x. > Something similar must be available for the laptop version of Intel's > Nehalem and for AMD. > >> Is it not as simple as checking for the svm or vt flags? >> >> egrep '(vt|svm)' /proc/cpuinfo >> >> Take a bootable LiveCD into your local computer shop and check. >> >>> 2.

As I understand it you want a laptop with a Core i7 processor to get EPT. I am not as familiar with AMD's offerings. I did not see the Core i7 offered on Dell laptops as of late January. > >>> 3.

So far (one whole week) I have not had any kvm related problems (the intel_drv xorg module is a different matter), and the performance has been nice. david > > Regards, > Jorge > -- > To unsubscribe from this list: send the line "unsubscribe kvm" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
