This is a recurring submission and includes corrections to various issue spotted. I guess I can just skip over reporting ubiquitous comma placement fixes… Highligts in this particular commit: - the "unsigned" type qualifier is completed to form a full type "unsigned int" - alphabetic -> lexicographic (that way we automatically define how numbers get sorted)

|
|
|
<para><command>systemd-detect-virt</command> detects
|
|
execution in a virtualized environment. It identifies
|
|
the virtualization technology and can distinguish 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>bochs</varname>, <varname>chroot</varname>,

<varname>openvz</varname>, <varname>lxc</varname>,
|
|
<varname>lxc-libvirt</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
|
|
passed).</para>
