This patch-set adds support for the new feature 'deflate-on-oom' that has been added to the QEMU virtio memory balloon a month ago. This feature lets a guest OS deflate balloon on OOM. With 'deflate-on-oom' enabled virtio balloon will release it's memory if possible right before an OOM termination of processes. QEMU commit with the complete feature description: http://git.qemu.org/?p=qemu.git;a=commit;h=e3816255bf4b6377bb405331e2ee0d... v2: * attribute renamed to 'autodeflate' [1/3][3/3] * capability check added [2/3][2/3] * ability to change 'autodeflate' for running domain wasn't added because QEMU doesn't allow to on/off 'deflate-on-oom' in runtime * more tests added [3/3] *** BLURB HERE *** Dmitry Andreev (3): conf: introduce 'autodeflate' attribute for memballoon device qemu: add capability check for memballoon 'autodeflate' feature qemu: add support of optional 'autodeflate' attribute docs/formatdomain.html.in | 10 ++ docs/schemas/domaincommon.rng | 5 + src/conf/domain_conf.c | 23 +++ src/conf/domain_conf.h | 1 + src/qemu/qemu_capabilities.c | 11 ++ src/qemu/qemu_capabilities.h | 2 + src/qemu/qemu_command.c | 11 ++ tests/qemucapabilitiesdata/caps_1.2.2-1.replies | 68 ++++++++- tests/qemucapabilitiesdata/caps_1.3.1-1.replies | 68 ++++++++- tests/qemucapabilitiesdata/caps_1.4.2-1.replies | 68 ++++++++- tests/qemucapabilitiesdata/caps_1.5.3-1.replies | 66 ++++++++- tests/qemucapabilitiesdata/caps_1.6.0-1.replies | 66 ++++++++- tests/qemucapabilitiesdata/caps_1.6.50-1.replies | 66 ++++++++- tests/qemucapabilitiesdata/caps_2.1.1-1.replies | 78 +++++++++- tests/qemucapabilitiesdata/caps_2.4.0-1.caps | 1 + tests/qemucapabilitiesdata/caps_2.4.0-1.replies | 146 ++++++++++++++++++- tests/qemucapabilitiesdata/caps_2.5.0-1.caps | 1 + tests/qemucapabilitiesdata/caps_2.5.0-1.replies | 161 ++++++++++++++++++++- .../qemuxml2argv-balloon-ccw-deflate.args | 20 +++ .../qemuxml2argv-balloon-ccw-deflate.xml | 21 +++ .../qemuxml2argv-balloon-device-deflate-off.args | 23 +++ .../qemuxml2argv-balloon-device-deflate-off.xml | 25 ++++ .../qemuxml2argv-balloon-device-deflate.args | 23 +++ .../qemuxml2argv-balloon-device-deflate.xml | 25 ++++ .../qemuxml2argv-balloon-mmio-deflate.args | 25 ++++ .../qemuxml2argv-balloon-mmio-deflate.xml | 30 ++++ tests/qemuxml2argvtest.c | 9 ++ 27 files changed, 990 insertions(+), 63 deletions(-) create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-ccw-deflate.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-ccw-deflate.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-device-deflate-off.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-device-deflate-off.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-device-deflate.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-device-deflate.xml create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-mmio-deflate.args create mode 100644 tests/qemuxml2argvdata/qemuxml2argv-balloon-mmio-deflate.xml -- 1.8.3.1
