[PATCH][RESEND] processMonitorEOFEvent:fix delet Domain object about the new VM in processMonitorEOFEvent()

From: 王鹏钧10288409 <10288409@zte.intra(a)LIN-184C297BAE7.zte.com.cn&gt; Virsh shutdown is executed firstly, virsh destroy is executed later, and VM is recreated again. In this process, due to will delet Domain object about the new VM in processMonitorEOFEvent(), which virDomainObjListRemove is called to remove objlist, the new VM cannot be found through virsh list command and qemu process is still running. Therefore, add virDomainObjListFindByName function checks to avoid delet Domain object about the new VM in objlist. This process chart of problem is as follows shutdown | destroy | create ============================+==================+=================== qemuMonitorIO | | qemuProcessHandleMonitorEOF | | | virDomainDestroy | | qemuProcessStop | | | qemuDomainCreateXML | | qemuProcessInit processMonitorEOFEvent | | qemuDomainRemoveInactive | | | | qemuProcessLaunch Signed-off-by: Wang PengJun <wang.pengjun1(a)zte.com.cn&gt; Signed-off-by: Yi Wang <wang.yi59(a)zte.com.cn&gt; --- src/qemu/qemu_driver.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index ee0963c30d..a504f89724 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -4024,6 +4024,7 @@ processMonitorEOFEvent(virQEMUDriver *driver, const char *auditReason = "shutdown"; unsigned int stopFlags = 0; virObjectEvent *event = NULL; + virDomainObj *obj; if (qemuProcessBeginStopJob(driver, vm, VIR_JOB_DESTROY, true) < 0) return; @@ -4055,7 +4056,12 @@ processMonitorEOFEvent(virQEMUDriver *driver, virObjectEventStateQueue(driver->domainEventState, event); endjob: - qemuDomainRemoveInactive(driver, vm); + virObjectUnlock(vm); + obj = virDomainObjListFindByName(driver->domains, vm->def->name); + if (vm == obj) + qemuDomainRemoveInactive(driver, vm); + virDomainObjEndAPI(&obj); + virObjectLock(vm); qemuDomainObjEndJob(vm); } -- 2.27.0
