+
+ <para><command>systemd-detect-virt</command> detects
+ execution in a virtualized environment. It identifies
+ the virtualization technology and can distuingish full
+ VM virtualization from container
+ virtualization.</para>
+
+ <para>When executed without <option>--quiet</option>
+ will print a short identifier for the detected
+ virtualization technology. The following technologies
+ are currently identified: <varname>qemu</varname>,
+ <varname>kvm</varname>, <varname>vmware</varname>,
+ <varname>microsoft</varname>,
+ <varname>oracle</varname>, <varname>xen</varname>,

+ <varname>systemd-nspawn</varname>.</para>
+
+ <para>If multiple virtualization solutions are used
+ only the "innermost" is detected and identified. That
+ means if both VM virtualization and container
+ virtualization are used in conjunction only the latter
+ will be identified (unless <option>--vm</option> is
