Although this display type can be used on its own, for any practical use case it makes sense to pair it with either VNC or SPICE display. The clear benefit of this display is that VNC gains OpenGL support, which it natively doesn't have, and SPICE gains remote OpenGL support (native OpenGL support only works locally through a UNIX socket, i.e. listen type=3Dsocket/none) Signed-off-by: Erik Skultety --- docs/formatdomain.html.in | 33 ++++++++++++- docs/schemas/domaincommon.rng | 3 ++ src/conf/domain_conf.c | 6 ++- src/conf/domain_conf.h | 1 + src/libxl/libxl_conf.c | 1 + src/qemu/qemu_command.c | 35 +++++++++++++- src/qemu/qemu_domain.c | 54 ++++++++++++++++++= ++++ src/qemu/qemu_driver.c | 2 + src/qemu/qemu_hotplug.c | 1 + src/qemu/qemu_process.c | 4 ++ src/vmx/vmx.c | 1 + tests/domaincapsschemadata/full.xml | 1 + tests/qemuxml2argvdata/graphics-egl-headless.args | 26 +++++++++++ tests/qemuxml2argvdata/graphics-egl-headless.xml | 31 +++++++++++++ .../qemuxml2argvdata/graphics-sdl-egl-headless.xml | 35 ++++++++++++++ .../graphics-spice-egl-headless.args | 31 +++++++++++++ .../graphics-spice-egl-headless.xml | 36 +++++++++++++++ .../graphics-spice-invalid-egl-headless.xml | 37 +++++++++++++++ .../graphics-vnc-egl-headless.args | 28 +++++++++++ .../qemuxml2argvdata/graphics-vnc-egl-headless.xml | 37 +++++++++++++++ tests/qemuxml2argvtest.c | 17 +++++++ .../graphics-spice-egl-headless.xml | 44 ++++++++++++++++++ .../graphics-vnc-egl-headless.xml | 42 +++++++++++++++++ tests/qemuxml2xmltest.c | 2 + 24 files changed, 504 insertions(+), 4 deletions(-) create mode 100644 tests/qemuxml2argvdata/graphics-egl-headless.args create mode 100644 tests/qemuxml2argvdata/graphics-egl-headless.xml create mode 100644 tests/qemuxml2argvdata/graphics-sdl-egl-headless.xml create mode 100644 tests/qemuxml2argvdata/graphics-spice-egl-headless.args create mode 100644 tests/qemuxml2argvdata/graphics-spice-egl-headless.xml create mode 100644 tests/qemuxml2argvdata/graphics-spice-invalid-egl-headl= ess.xml create mode 100644 tests/qemuxml2argvdata/graphics-vnc-egl-headless.args create mode 100644 tests/qemuxml2argvdata/graphics-vnc-egl-headless.xml create mode 100644 tests/qemuxml2xmloutdata/graphics-spice-egl-headless.xml create mode 100644 tests/qemuxml2xmloutdata/graphics-vnc-egl-headless.xml diff --git a/docs/formatdomain.html.in b/docs/formatdomain.html.in index a3afe137bf..9dd22554ad 100644 --- a/docs/formatdomain.html.in +++ b/docs/formatdomain.html.in @@ -6299,7 +6299,8 @@ qemu-kvm -net nic,model=3D? /dev/null
