[libvirt] [PATCH v4 0/3] Don't pm suspend guest if it's unable to wake up

changes from v3: - patch 3 removed. We no longer consider PM_WAKEUP_SUPPORT a cap. It is confusing to have a 'runtime cap' that can't be resolved inside qemu_capabilities.c. The suspend operation isn't time critical per se, and a call to QMP each time 'virsh dompmsuspend' is executed is not dreadful to the user experience. More information and discussion can be found at [1]. - due to the change above, patch 4 now executes the query-current-machine QMP call (if the running QEMU instance supports it) during qemuDomainPMSuspendForDuration to check if the guest has wakeup support. - previous patch link: [1] https://www.redhat.com/archives/libvir-list/2019-April/msg00767.html Daniel Henrique Barboza (2): qemu_capabilities: Add QEMU_CAPS_QUERY_CURRENT_MACHINE qemuDomainPMSuspendForDuration: check for wake-up support Michal Prívozník (1): qemu_monitor: Introduce handler for 'query-current-machine' command src/qemu/qemu_capabilities.c | 2 + src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_driver.c | 54 +++++++++++++++++++ src/qemu/qemu_monitor.c | 10 ++++ src/qemu/qemu_monitor.h | 9 ++++ src/qemu/qemu_monitor_json.c | 50 +++++++++++++++++ src/qemu/qemu_monitor_json.h | 5 ++ .../caps_4.0.0.riscv32.xml | 1 + .../caps_4.0.0.riscv64.xml | 1 + .../caps_4.0.0.x86_64.xml | 1 + 10 files changed, 134 insertions(+) -- 2.20.1
