That CPU feature is not visible inside a VM, it's stripped. The OS doesn't need it, but the hypervisor running the OS does. In this case, VB needs VT-x for certain features, like 64 bit Guests and SMP, the Guest can do without and there is no benefit to have it there.

I don't know about your command but mine tells me all about the hosts CPU inside the guest. (emulated info but still enough to tell if it is 64-bit)
Also the Fedora i686 (your profile) is the 32-bit version

His command searches if 'vmx' or 'svm' is in /proc/cpuinfo and outputs it, else show nothing. Since it doesn't show any output, the option isn't available. Makes sense, as stated above.
