hvm_xs_strings.h specifies xenstore entries which can be used to set or override smbios strings. hvmloader has support for reading them, but xl/libxl support is not wired up. Allow specifying the strings with the new xl.cfg option: smbios=["bios_vendor=Xen Project","system_version=1.0"] In terms of strings, the SMBIOS specification 3.5 says: https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.5.0.pdf """ Strings must be encoded as UTF-8 with no byte order mark (BOM). For compatibility with older SMBIOS parsers, US-ASCII characters should be used. NOTE There is no limit on the length of each individual text string. However, the length of the entire structure table (including all strings) must be reported in the Structure Table Length field of the 32-bit Structure Table Entry Point (see 5.2.1) and/or the Structure Table Maximum Size field of the 64-bit Structure Table Entry Point (see 5.2.2). """ The strings aren't checked for utf-8 or length. hvmloader has a sanity check on the overall length. The libxl_smbios_type enum starts at 1 since otherwise the 0th key is not printed in the json output.
