[libvirt PATCH v4 00/11] Add QEMU "-display dbus" support

From: Marc-André Lureau <marcandre.lureau(a)redhat.com&gt; Hi, This series implements supports for the QEMU "-display dbus" support, available since 7.0. By default, libvirt will start a private VM bus (sharing and reusing the existing "vmstate" VM bus & code). The feature set should cover the needs to replace Spice as local client of choice, including 3daccel/dmabuf, audio, clipboard sharing, usb redirection, and arbitrary chardev/channels (for serial etc). The test Gtk4 client is also in progress, currently in development at https://gitlab.com/marcandre.lureau/qemu-display/. virt-viewer & boxes will need a port to Gtk4 to make use of the shared widget. thanks v4: - rebased, dropped some patches, updated versions in docs, code adjustments etc - dropped clipboard option, as standalone qemu-vdagent support landed v3: after QEMU 7.0 dev cycle opening and merge - rebased - add 7.0 x86-64 capabilities (instead of tweaking 6.2) - fix version annotations Marc-André Lureau (11): qemu: add -display dbus capability check conf: add <graphics type='dbus'> qemu: start the D-Bus daemon for the display qemu: add -display dbus support virsh: report the D-Bus bus URI for domdisplay conf: add <audio type='dbus'> support qemu: add audio type 'dbus' conf: add <serial type='dbus'> qemu: add -chardev dbus support qemu: add usbredir type 'dbus' docs: document <graphics> type dbus NEWS.rst | 5 + docs/formatdomain.rst | 43 +++++- src/bhyve/bhyve_command.c | 1 + src/conf/domain_conf.c | 129 +++++++++++++++++- src/conf/domain_conf.h | 14 ++ src/conf/domain_validate.c | 41 ++++-- src/conf/schemas/basictypes.rng | 7 + src/conf/schemas/domaincommon.rng | 63 +++++++++ src/libxl/libxl_conf.c | 1 + src/libxl/libxl_domain.c | 1 + src/libxl/libxl_driver.c | 1 + src/qemu/qemu_capabilities.c | 4 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 65 ++++++++- src/qemu/qemu_domain.c | 1 + src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_extdevice.c | 13 ++ src/qemu/qemu_hotplug.c | 1 + src/qemu/qemu_monitor_json.c | 10 ++ src/qemu/qemu_process.c | 41 +++++- src/qemu/qemu_validate.c | 33 +++++ src/security/security_dac.c | 2 + src/vmx/vmx.c | 1 + .../domaincapsdata/qemu_7.0.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_7.0.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_7.0.0.x86_64.xml | 1 + .../domaincapsdata/qemu_7.1.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_7.1.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_7.1.0.x86_64.xml | 1 + .../caps_7.0.0.x86_64.xml | 1 + .../caps_7.1.0.x86_64.xml | 1 + .../graphics-dbus-address.args | 30 ++++ .../graphics-dbus-address.xml | 35 +++++ .../qemuxml2argvdata/graphics-dbus-audio.args | 33 +++++ .../qemuxml2argvdata/graphics-dbus-audio.xml | 45 ++++++ .../graphics-dbus-chardev.args | 32 +++++ .../graphics-dbus-chardev.xml | 43 ++++++ tests/qemuxml2argvdata/graphics-dbus-p2p.args | 30 ++++ tests/qemuxml2argvdata/graphics-dbus-p2p.xml | 33 +++++ .../graphics-dbus-usbredir.args | 34 +++++ .../graphics-dbus-usbredir.xml | 30 ++++ tests/qemuxml2argvdata/graphics-dbus.args | 30 ++++ tests/qemuxml2argvdata/graphics-dbus.xml | 33 +++++ tests/qemuxml2argvtest.c | 17 +++ .../graphics-dbus-address.xml | 1 + .../graphics-dbus-audio.xml | 1 + .../graphics-dbus-chardev.xml | 1 + .../qemuxml2xmloutdata/graphics-dbus-p2p.xml | 1 + tests/qemuxml2xmloutdata/graphics-dbus.xml | 1 + tests/qemuxml2xmltest.c | 17 +++ tests/testutilsqemu.c | 1 + tools/virsh-domain.c | 24 +++- 52 files changed, 948 insertions(+), 20 deletions(-) create mode 100644 tests/qemuxml2argvdata/graphics-dbus-address.args create mode 100644 tests/qemuxml2argvdata/graphics-dbus-address.xml create mode 100644 tests/qemuxml2argvdata/graphics-dbus-audio.args create mode 100644 tests/qemuxml2argvdata/graphics-dbus-audio.xml create mode 100644 tests/qemuxml2argvdata/graphics-dbus-chardev.args create mode 100644 tests/qemuxml2argvdata/graphics-dbus-chardev.xml create mode 100644 tests/qemuxml2argvdata/graphics-dbus-p2p.args create mode 100644 tests/qemuxml2argvdata/graphics-dbus-p2p.xml create mode 100644 tests/qemuxml2argvdata/graphics-dbus-usbredir.args create mode 100644 tests/qemuxml2argvdata/graphics-dbus-usbredir.xml create mode 100644 tests/qemuxml2argvdata/graphics-dbus.args create mode 100644 tests/qemuxml2argvdata/graphics-dbus.xml create mode 120000 tests/qemuxml2xmloutdata/graphics-dbus-address.xml create mode 120000 tests/qemuxml2xmloutdata/graphics-dbus-audio.xml create mode 120000 tests/qemuxml2xmloutdata/graphics-dbus-chardev.xml create mode 120000 tests/qemuxml2xmloutdata/graphics-dbus-p2p.xml create mode 120000 tests/qemuxml2xmloutdata/graphics-dbus.xml -- 2.36.1
