The patch is based on the possiblity in the QEmu command line to add -smbios options allowing to override the default values picked by QEmu. We need to detect this first from QEmu help output. If the domain is defined with smbios to be inherited from host then we pass the values coming from the Host own SMBIOS, but if the domain is defined with smbios to come from sysinfo, we use the ones coming from the domain definition. * src/qemu/qemu_conf.h: add the QEMUD_CMD_FLAG_SMBIOS_TYPE enum value * src/qemu/qemu_conf.c: scan the help output for the smbios support, and if available add support based on the domain definitions, and host data * tests/qemuhelptest.c: add the new enum in the outputs Signed-off-by: Daniel Veillard <veillard(a)redhat.com&gt; --- src/qemu/qemu_conf.c | 117 ++++++++++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_conf.h | 3 +- tests/qemuhelptest.c | 15 ++++-- 3 files changed, 129 insertions(+), 6 deletions(-)
