+Requirements
+------------
+
+To use KVM with enabled hardware virtualization, your hardware has
+to support virtualization extensions. (Intel VT-x for Intel Processors,
+and AMD-V for AMD Processors)
+
+To check if your hardware supports it, you can check the output of:
+[source,bash]
+egrep '(vmx|svm)' /proc/cpuinfo
+
+Additionally you have to enable those extensions in your BIOS/EFI.
+
+NOTE: You can use Qemu Virtual Machines without KVM/Hardware Virtualization,
+but the performance will certainly be very low
