I'm working on a new DevOps system that relies upon Chef, Vagrant and VirtualBox. To duplicate the system I needed to run Ubuntu Trusty 64 bit edition in the virtual box. Vagrant setup failed with timeouts. When I ran the 64 bit VM Vagrant made through the VirtualBox client it said I did not have VT-x visualization on my machine.
I have a HP ProBook 4730s.
Choose system features
VirtualBox still refuses to run ubuntu 64. Some googling reveals you have to enable the bios to change the setting, rather than just view. WTF?
Some stupid setting
Now it works.
