#vt-x

Good links: http://jensd.be/?p=207 This one is a good manual overview of enabling VT-x etc and getting grub2 updated to boot automatically with those options. It also covers network settings using a bridge, but IMHO errs in choosing "virbr0" as the name of this bridge, which can conflict with the interface automatically used by libvirt (it runs dnsmasq on it by default). http://www.cyberciti.biz/faq/linux-kvm-disable-virbr0-nat-interface/ http://lampros.chaidas.com/index.php/2014/09/01/centos-7-kvm-installation-and-bridge-networking/ http://www.rdoxenham.com/?p=275 http://nts.strzibny.name/inception-running-vagrant-inside-vagrant-with-kvm/

How do I enable VT-X?

I’d like to provide a guest OS with multiple CPUs in VirtualBox. My host machine is a quad core HP Compaq and uses the Intel Core 2 vPro hardware.

However, when I try to enable the setting in vbox, I get an error that VT-x is not available. Is this something that I can enable somewhere? how do I find out otherwise whether my hardware supports it?
