===== 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 =====
