+===== Check for virtualization support =====
+These extensions are called Intel VT or AMD-V.
+<code>
+$ egrep '^flags.*(vmx|svm)' /proc/cpuinfo
+</code>
+If this command results in nothing printed, your system does not support the relevant virtualization extensions. You can still use QEMU/KVM, but the emulator will fall back to software virtualization, which is much slower.
 ===== Virtualization group =====

+$ dnf group info virtualization
