Function qemuProcessUpdateDevices was called at qemuProcessReconnect when we detach net device lively and killed libvirtd service at middle. qemu detached the device but libvirtd don't save it at runDir. when libvirtd restart, libvirtd will detach net device but qemu will return fail because device was not found. then libvirtd qemuProcessReconnect failed and goto error. libvirtd kill qemu. To avoid qemu is killed by libvirtd, qemuDomainRemoveDevice will not return failed. --- src/qemu/qemu_process.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 6d242b1..9f9393b 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -3234,7 +3234,7 @@ qemuProcessUpdateDevices(virQEMUDriverPtr driver, if (!virStringListHasString(qemuDevices, *tmp) && virDomainDefFindDevice(vm->def, *tmp, &dev, false) == 0 && qemuDomainRemoveDevice(driver, vm, &dev) < 0) { - goto cleanup; + VIR_WARN("failed to remove device %s at reconnect process", *tmp); } tmp++; } -- 2.8.3
