[Qemu-devel] [PATCH 0/2] qemu: SMBIOS passing support

[Alex Williamson]

This series adds a new -smbios option for x86 that allows individual
SMBIOS entries to be passed into the guest VM.  This follows the same
basic path as the support for loading ACPI tables.  While SMBIOS is
independent of ACPI, I chose to add the smbios_entry_add() function to
acpi.c because they're both somewhat PC BIOS related (and ia64 can
support SMBIOS and might be able to make use of it there).

This feature allows the guest to see certain properties of the host if
configured correctly.  For instance, the system model and serial number
in the type 1 entry.  Obviously its only built at boot, so doesn't get
updated for migration scenarios.  User provided entries will supersede
generated entries, so care should be taken when passing entries which
describe physical properties, such as memory size and address ranges.
Thanks,

Alex
