[libvirt] [PATCH v2 00/31] qemu: Add support for unavailable-features

QEMU 2.8.0 adds support for unavailable-features in query-cpu-definitions reply. The unavailable-features array lists CPU features which prevent a corresponding CPU model from being usable on current host. It can only be used when all the unavailable features are disabled. Empty array means the CPU model can be used without modifications. Changes in v2: - many; the way we probe QEMU was rewritten so that we probe both KVM and TCG capabilities and store them separately whenever we expect them to be different Big thanks to Andrea Bolognani for providing the updated replies data from aarch64 and ppc64le machines. Jiri Denemark (31): qemu: Make QMP probing process reusable qemu: Use -machine when probing capabilities via QMP qemu: Probe KVM state earlier qemucapsprobe: Ignore all greetings except the first one qemu: Enable KVM when probing capabilities qemu: Discard caps cache when KVM availability changes qemu: Use saner defaults for domain capabilities qemu: Don't return unusable virttype in domain capabilities qemu: Refactor virQEMUCapsCacheLookup qemu: Refresh caps in virQEMUCapsCacheLookupByArch qemu: Introduce virQEMUCapsLoadCPUModels qemu: Introduce virQEMUCapsFormatCPUModels qemu: Probe CPU models for KVM and TCG tests: Update capabilities for QEMU 1.2.2 tests: Update capabilities for QEMU 1.3.1 tests: Update capabilities for QEMU 1.4.2 tests: Update capabilities for QEMU 1.5.3 tests: Update capabilities for QEMU 1.6.0 tests: Update capabilities for QEMU 1.7.0 tests: Update capabilities for QEMU 2.1.1 tests: Update capabilities for QEMU 2.4.0 tests: Update capabilities for QEMU 2.5.0 tests: Update capabilities for QEMU 2.6.0 tests: Update capabilities for QEMU 2.6.0 (aarch64, GICv2) qemu: Avoid reporting "host" as a supported CPU model tests: Update capabilities for QEMU 2.6.0 (aarch64, GICv3) tests: Update capabilities for QEMU 2.6.0 (ppc64le) tests: Update capabilities for QEMU 2.7.0 tests: Add QEMU 2.8.0 capabilities data tests: Add QEMU 2.8.0 domain capabilities tests qemu: Add support for unavailable-features src/conf/domain_capabilities.c | 6 +- src/conf/domain_capabilities.h | 3 +- src/qemu/qemu_capabilities.c | 684 +- src/qemu/qemu_capabilities.h | 15 +- src/qemu/qemu_capspriv.h | 8 + src/qemu/qemu_driver.c | 27 +- src/qemu/qemu_monitor.h | 1 + src/qemu/qemu_monitor_json.c | 18 + src/qemu/qemu_process.c | 3 +- tests/domaincapsschemadata/qemu_2.6.0.ppc64le.xml | 1 + .../domaincapsschemadata/qemu_2.8.0-tcg.x86_64.xml | 116 + tests/domaincapsschemadata/qemu_2.8.0.x86_64.xml | 116 + tests/domaincapstest.c | 8 + .../qemucapabilitiesdata/caps_1.2.2.x86_64.replies | 216 +- tests/qemucapabilitiesdata/caps_1.2.2.x86_64.xml | 68 +- .../qemucapabilitiesdata/caps_1.3.1.x86_64.replies | 172 +- tests/qemucapabilitiesdata/caps_1.3.1.x86_64.xml | 74 +- .../qemucapabilitiesdata/caps_1.4.2.x86_64.replies | 170 +- tests/qemucapabilitiesdata/caps_1.4.2.x86_64.xml | 74 +- .../qemucapabilitiesdata/caps_1.5.3.x86_64.replies | 170 +- tests/qemucapabilitiesdata/caps_1.5.3.x86_64.xml | 74 +- .../qemucapabilitiesdata/caps_1.6.0.x86_64.replies | 170 +- tests/qemucapabilitiesdata/caps_1.6.0.x86_64.xml | 74 +- .../qemucapabilitiesdata/caps_1.7.0.x86_64.replies | 170 +- tests/qemucapabilitiesdata/caps_1.7.0.x86_64.xml | 74 +- .../qemucapabilitiesdata/caps_2.1.1.x86_64.replies | 173 +- tests/qemucapabilitiesdata/caps_2.1.1.x86_64.xml | 77 +- .../qemucapabilitiesdata/caps_2.4.0.x86_64.replies | 182 +- tests/qemucapabilitiesdata/caps_2.4.0.x86_64.xml | 86 +- .../qemucapabilitiesdata/caps_2.5.0.x86_64.replies | 182 +- tests/qemucapabilitiesdata/caps_2.5.0.x86_64.xml | 86 +- .../caps_2.6.0-gicv2.aarch64.replies | 194 +- .../caps_2.6.0-gicv2.aarch64.xml | 93 +- .../caps_2.6.0-gicv3.aarch64.replies | 207 +- .../caps_2.6.0-gicv3.aarch64.xml | 95 +- .../caps_2.6.0.ppc64le.replies | 1406 +- tests/qemucapabilitiesdata/caps_2.6.0.ppc64le.xml | 1296 +- .../qemucapabilitiesdata/caps_2.6.0.x86_64.replies | 182 +- tests/qemucapabilitiesdata/caps_2.6.0.x86_64.xml | 86 +- .../qemucapabilitiesdata/caps_2.7.0.x86_64.replies | 185 +- tests/qemucapabilitiesdata/caps_2.7.0.x86_64.xml | 89 +- .../qemucapabilitiesdata/caps_2.8.0.x86_64.replies | 14246 +++++++++++++++++++ tests/qemucapabilitiesdata/caps_2.8.0.x86_64.xml | 293 + tests/qemucapabilitiestest.c | 6 + tests/qemucapsprobemock.c | 9 +- tests/qemumonitorjsontest.c | 27 +- tests/qemuxml2argvtest.c | 39 +- 47 files changed, 20114 insertions(+), 1637 deletions(-) create mode 100644 tests/domaincapsschemadata/qemu_2.8.0-tcg.x86_64.xml create mode 100644 tests/domaincapsschemadata/qemu_2.8.0.x86_64.xml create mode 100644 tests/qemucapabilitiesdata/caps_2.8.0.x86_64.replies create mode 100644 tests/qemucapabilitiesdata/caps_2.8.0.x86_64.xml -- 2.10.2
