SMBIOS Type 11 strings

Synopsis

/sys/firmware/dmi/entries/11-*/raw

Description

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 kernel-command-line(7) parameters but generally are under control of the VMM rather than the boot loader or UKI​.

For details on SMBIOS Type 11 see the System Management BIOS​[1] specifications​.

The following strings are supported:

io​.systemd​.credential:CREDENTIAL=VALUE,  io​.systemd​.credential​.binary:CREDENTIAL=VALUE

This allows passing additional system credentials into the system, in textual or binary (Base64) form​. See systemd.exec(5) and System and Service Credentials​[2] for details​.
