But domain destroy without --graceful can work, SIGKILL will be emitted to the stopped process after 10 secs which always kills a process even one that is currently stopped. So report an error after burning out waiting time in this case. --- src/qemu/qemu_process.c | 2 +- src/util/virprocess.c | 5 +++-- 2 files changed, 4 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 4a7c612..e5b4679 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -3930,7 +3930,7 @@ qemuProcessKill(virDomainObjPtr vm, unsigned int flags) } } - if ((flags & VIR_QEMU_PROCESS_KILL_NOWAIT)) { + if (flags & VIR_QEMU_PROCESS_KILL_NOWAIT) { virProcessKill(vm->pid, (flags & VIR_QEMU_PROCESS_KILL_FORCE) ?
