Tip: Using Linux to check if CPU has Intel VT-x

To verify if a Intel CPU supports the company's technology for virtualization take a look at /proc/cpuinfo and check for the vmx CPU flag.
 $ grep vmx /proc/cpuinfo 
If your interested in reading the ouput of /proc/cpuinfo in more detail:
 $ cat /proc/cpuinfo | less 
The procfs filesystem contains loads of process and system information and /proc/cpuinfo in particular contains information regarding the CPU, such as vendor, cache size, clockspeed, cores and CPU flags.
