+
+                <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>,

+
+                <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
