Adds a qxl-ram attribute globaly to the video.model element, that changes the resulting qemu command line only if video.type == "qxl". That attribute gets a default value of 64*1024 only if model.type is "qxl". In effect not changing any xml or argv for non qxl devices. For qxl devices a new property is set: -global qxl-vga.ram_size=<ram>*1024 or -global qxl.ram_size=<ram>*1024 For the main and secondary qxl devices respectively. The default for the qxl ram bar is the same as the default for the qxl vram bar, 64*1024. --- I've added a qxl-ram attribute. There is no precedent for adding am attribute prefixed like this, so I'm open for any other suggestion on how to do it. docs/schemas/domaincommon.rng | 9 +++- src/conf/domain_conf.c | 19 ++++++- src/conf/domain_conf.h | 1 + src/qemu/qemu_command.c | 58 ++++++++++++++++++---- .../qemuxml2argv-graphics-spice-compression.args | 2 +- .../qemuxml2argv-graphics-spice-compression.xml | 4 +- .../qemuxml2argv-graphics-spice-qxl-vga.args | 2 +- .../qemuxml2argv-graphics-spice-qxl-vga.xml | 4 +- .../qemuxml2argv-graphics-spice.args | 2 +- .../qemuxml2argv-graphics-spice.xml | 4 +- .../qemuxml2argv-video-device-pciaddr-default.args | 6 +-- 11 files changed, 86 insertions(+), 25 deletions(-) diff --git a/docs/schemas/domaincommon.rng b/docs/schemas/domaincommon.rng index 67ae864..50fc834 100644 --- a/docs/schemas/domaincommon.rng +++ b/docs/schemas/domaincommon.rng @@ -2251,7 +2251,9 @@ </define> <!-- A video adapter description, allowing configuration of device -
