Use the lscpu command on a Linux server to find out Virtualization support for an Intel or AMD cpu. The syntax is:
lscpu lscpu | more lscpu | grep Virtualization

The VT-x means Intel Virtualization support enabled in the BIOS.
The AMD-V means AMD Virtualization support enabled in the BIOS.
The VIA VT means VIA high end cpu Virtualization support enabled in the BIOS which is compatible with Intel VT-x.
