    <title>Description</title>

    <para>Various OS components process SMBIOS Type 11 vendor strings that a virtual machine manager (VMM)
    may set and a virtual machine (VM) receives. SMBIOS Type 11 vendor strings may play a similar role as
    <citerefentry><refentrytitle>kernel-command-line</refentrytitle><manvolnum>1</manvolnum></citerefentry>
    parameters but generally are under control of the VMM rather than the boot loader or UKI.</para>

    <para>For details on SMBIOS Type 11 see the <ulink url="https://www.dmtf.org/standards/smbios/">System
    Management BIOS</ulink> specifications.</para>
