SeaBIOS >= 1.11 / QEMU >= 2.11 no longer requires the 'sga' device for serial console output from the BIOS. It can be done directly with graphics=off machine option. This appears to be live migration compatible, despite changing the number of option ROMS loaded, though I need a little more testing to fully confirm this. Daniel P. Berrangé (4): qemu: prevent use of <bios useserial='yes'> on non-x86 arches qemu: tweak error message to be more general purpose qemu: switch to use -M graphics=off instead of -device sga qemu: stop probing for '-device sga' support src/qemu/qemu_capabilities.c | 3 +-- src/qemu/qemu_capabilities.h | 2 +- src/qemu/qemu_command.c | 25 ++++++++----------- src/qemu/qemu_validate.c | 15 ++++++++--- .../caps_2.11.0.x86_64.xml | 1 - .../caps_2.12.0.x86_64.xml | 1 - .../caps_3.0.0.x86_64.xml | 1 - .../caps_3.1.0.x86_64.xml | 1 - .../caps_4.0.0.x86_64.xml | 1 - .../caps_4.1.0.x86_64.xml | 1 - .../caps_4.2.0.x86_64.xml | 1 - .../caps_5.0.0.x86_64.xml | 1 - .../caps_5.1.0.x86_64.xml | 1 - .../caps_5.2.0.x86_64.xml | 1 - .../caps_6.0.0.x86_64.xml | 1 - .../caps_6.1.0.x86_64.xml | 1 - tests/qemuxml2argvdata/bios.args | 3 +-- tests/qemuxml2argvtest.c | 3 +-- 18 files changed, 25 insertions(+), 38 deletions(-) -- 2.31.1
