Right now there is one supported event: guest panic. Also, the cpu runstate is preserved during save/load vm and migration. Thus, if vm is panicked during migration, we can still know it by quring the status of vm in destination host when migration completes. v12: http://lists.nongnu.org/archive/html/qemu-devel/2013-01/msg04120.html changes from v12: - no DO_UPCASE - the interface is only for x86 now - request 4 bytes io range(hw/kvm_pv_event.c) - rebase to the latest tree Hu Tao (7): save/load cpu runstate update kernel headers add a new runstate: RUN_STATE_GUEST_PANICKED add a new qevent: QEVENT_GUEST_PANICKED introduce a new qom device to deal with panicked event allower the user to disable pv event support pv event: add document to describe the usage Wen Congyang (1): start vm after resetting it docs/pv-event.txt | 17 ++++ hw/kvm/Makefile.objs | 2 +- hw/kvm/pv_event.c | 198 +++++++++++++++++++++++++++++++++++++++ hw/pc_piix.c | 12 +++ include/block/block.h | 2 + include/monitor/monitor.h | 1 + include/sysemu/kvm.h | 2 + include/sysemu/sysemu.h | 2 + kvm-stub.c | 4 + linux-headers/asm-x86/kvm_para.h | 1 + linux-headers/linux/kvm_para.h | 6 ++ migration.c | 7 +- monitor.c | 6 +- qapi-schema.json | 6 +- qemu-options.hx | 3 +- qmp.c | 5 +- savevm.c | 1 + vl.c | 56 ++++++++++- 18 files changed, 314 insertions(+), 17 deletions(-) create mode 100644 docs/pv-event.txt create mode 100644 hw/kvm/pv_event.c -- 1.8.1.4
