How to check for virtualization support in Linux?

It’s very useful to know if your hardware has support for accelerated and nested virtualization. You can check for virtualization support in Linux by using the following command:

lscpu | grep Virtualization
  • if your device has an Intel based CPU, the output should be: VT-x;
  • but if your device has an AMD based CPU, the output should be: AMD-V;
  • and the output is blank if the device has no support for accelerated and nested virtualization.
