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