For the EnrollDefaultKeys application, the hypervisor is expected to add a string entry to the "OEM Strings" (Type 11) SMBIOS table, with the following format:
4e32566d-8e9e-4f52-81d3-5bb9715f9727:<Base64 X509 cert for PK and first KEK> The string representation of the GUID at the front is the "application prefix", in terms of QEMU commit <https://git.qemu.org/?p=qemu.git;a=commit;h=2d6dcbf93fb0>. Introduce this GUID in the usual manner.
