This is my motherboard: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01324212&lc=en&cc=ca&dlc=en&product=3691066 The virtualization technology is enabled from bios and KVM (not QEMU) virtual machine work correctly! >1. Your hardware (your chipset) doesn't support VT-d During the installation process I done the command "egrep '(vmx|svm)' --color=always /proc/cpuinfo" to verify if processor supports virtualization (from https://help.ubuntu.com/community/KVM/Installation manual) and the prompt return me right elements. So the cpu is Q9xxx (i don't remember) and have vt-d. From bios I enabled VT technology from first boot. -- 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
