Re: [libvirt PATCH v3 00/16] Add QEMU "-display dbus" support

From: Marc-André Lureau <marcandre.lureau(a)redhat.com&gt; Hi, This series implements supports for the uQEMU "-display dbus" support, that landed earlier this week for 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/. A few dependencies, such as zbus, require an upcoming release. virt-viewer & boxes will need a port to Gtk4 to make use of the shared widget. Comments welcome, as we can still adjust the QEMU side etc. thanks 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 (16): qemu: add chardev-vdagent capability check qemu: add -display dbus capability check qemucapabilitiestest: Add x64 test data for the qemu-7.0 development cycle conf: add <graphics type='dbus'> qemu: start the D-Bus daemon for the display qemu: add -display dbus support virsh: refactor/split cmdDomDisplay() virsh: report the D-Bus bus URI for domdisplay conf: add <audio type='dbus'> support qemu: add audio type 'dbus' conf: add dbus <clipboard> qemu: add dbus clipboard sharing conf: add <serial type='dbus'> qemu: add -chardev dbus support qemu: add usbredir type 'dbus' docs: document <graphics> type dbus NEWS.rst | 7 +- docs/formatdomain.rst | 43 +- docs/schemas/basictypes.rng | 7 + docs/schemas/domaincommon.rng | 71 + src/bhyve/bhyve_command.c | 1 + src/conf/domain_conf.c | 141 +- src/conf/domain_conf.h | 15 + src/conf/domain_validate.c | 41 +- src/libxl/libxl_conf.c | 1 + src/qemu/qemu_capabilities.c | 8 + src/qemu/qemu_capabilities.h | 4 + src/qemu/qemu_command.c | 77 +- 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 | 231 + .../domaincapsdata/qemu_7.0.0-tcg.x86_64.xml | 237 + tests/domaincapsdata/qemu_7.0.0.x86_64.xml | 231 + .../caps_6.1.0.x86_64.xml | 1 + .../caps_6.2.0.aarch64.xml | 1 + .../caps_6.2.0.x86_64.xml | 1 + .../caps_7.0.0.x86_64.replies | 37335 ++++++++++++++++ .../caps_7.0.0.x86_64.xml | 3720 ++ .../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 + .../graphics-dbus-clipboard.args | 31 + .../graphics-dbus-clipboard.xml | 35 + 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 | 22 + .../graphics-dbus-address.xml | 1 + .../graphics-dbus-audio.xml | 1 + .../graphics-dbus-chardev.xml | 1 + .../graphics-dbus-clipboard.xml | 1 + .../qemuxml2xmloutdata/graphics-dbus-p2p.xml | 1 + tests/qemuxml2xmloutdata/graphics-dbus.xml | 1 + tests/qemuxml2xmltest.c | 20 + tools/virsh-domain.c | 366 +- 52 files changed, 42981 insertions(+), 192 deletions(-) create mode 100644 tests/domaincapsdata/qemu_7.0.0-q35.x86_64.xml create mode 100644 tests/domaincapsdata/qemu_7.0.0-tcg.x86_64.xml create mode 100644 tests/domaincapsdata/qemu_7.0.0.x86_64.xml create mode 100644 tests/qemucapabilitiesdata/caps_7.0.0.x86_64.replies create mode 100644 tests/qemucapabilitiesdata/caps_7.0.0.x86_64.xml 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-clipboard.args create mode 100644 tests/qemuxml2argvdata/graphics-dbus-clipboard.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-clipboard.xml create mode 120000 tests/qemuxml2xmloutdata/graphics-dbus-p2p.xml create mode 120000 tests/qemuxml2xmloutdata/graphics-dbus.xml -- 2.34.1.8.g35151cf07204
