[Qemu-devel] [PATCH v2 3/3] qtest: add migrate-test
From: Jason Baron Tests a single 'pc' machine migration on the same host. Would be nice to extend the test matrix to various machine versions, but that requires building multiple qemu binaries, which is a bit awkward in the context of qtest. Testing migration between different machine versions with the same binary doesn't seem too useful.

We could test migration between TCG, Xen and KVM if two of those are available. > > Signed-off-by: Jason Baron > --- > tests/Makefile |2 + > tests/libqtest.c | 98 - > tests/libqtest.h | 15 +++- > tests/migrate-test.c | 68 ++ > 4 files changed, 179 insertions(+), 4 deletions(-) > create mode 100644 tests/migrate-test.c > > diff --git a/tests/Makefile b/tests/Makefile > index 1756b47..3f0c5a2 100644 > --- a/tests/Makefile > +++ b/tests/Makefile > @@ -25,6 +25,7 @@ check-block-$(CONFIG_POSIX) += tests/qemu-iotests-quick.sh > check-qtest-i386-y = tests/fdc-test$(EXESUF) > check-qtest-i386-y += tests/hd-geo-test$(EXESUF) > check-qtest-i386-y += tests/rtc-test$(EXESUF) > +check-qtest-i386-y += tests/migrate-test$(EXESUF) > check-qtest-x86_64-y = $(check-qtest-i386-y) > check-qtest-sparc-y = tests/m48t59-test$(EXESUF) > check-qtest-sparc64-y = tests/m48t59-test$(EXESUF) > @@ -78,6 +79,7 @@ tests/rtc-test$(EXESUF): tests/rtc-test.o $(trace-obj-y) > tests/m48t59-test$(EXESUF): tests/m48t59-test.o $(trace-obj-y) > tests/fdc-test$(EXESUF): tests/fdc-test.o tests/libqtest.o $(trace-obj-y) > tests/hd-geo-test$(EXESUF): tests/hd-geo-test.o tests/libqtest.o > $(trace-obj-y) > +tests/migrate-test$(EXESUF): tests/migrate-test.o > > # QTest rules > > diff --git a/tests/libqtest.c b/tests/libqtest.c > index 994cd2f..28cbea9 100644 > --- a/tests/libqtest.c > +++ b/tests/libqtest.c > @@ -28,6 +28,9 @@ > > #include "compiler.h" > #include "osdep.h" > +#include "qjson.h" > +#include "qdict.h" > +#include "qbool.h" > > #define MAX_IRQ 256 > > @@ -42,6 +45,8 @@ struct QTestState > gchar *pid_file; > char *socket_path, *qmp_socket_path; > char *tmp_dir; > +/* uri to use for incoming migration */ > +char *incoming_uri; > }; > > #define g_assert_no_errno(ret) do { \ > @@ -102,7 +107,7 @@ static pid_t qtest_qemu_pid(QTestState *s) > return pid; > } > > -QTestState *qtest_init(const char *extra_args) > +QTestState *qtest_init(const char *extra_args, const char *incoming_uri) > { > QTestState *s; > int sock, qmpsock, ret, i; > @@ -113,13 +118,14 @@ QTestState *qtest_init(const char *extra_args) > qemu_binary = getenv("QTEST_QEMU_BINARY"); > g_assert(qemu_binary != NULL); > > -s = g_malloc(sizeof(*s)); > +s = g_malloc0(sizeof(*s)); > > s->tmp_dir = g_strdup_printf("/tmp/qtest-%d-XX", getpid()); > g_assert(mkdtemp(s->tmp_dir) != NULL); > s->socket_path = g_strdup_printf("%s/%s", s->tmp_dir, "sock"); > s->qmp_socket_path = g_strdup_printf("%s/%s", s->tmp_dir, "qmp"); > s->pid_file = g_strdup_printf("%s/%s", s->tmp_dir, "pid"); > +s->incoming_uri = g_strdup(incoming_uri); > > sock = init_socket(s->socket_path); > qmpsock = init_socket(s->qmp_socket_path); > @@ -178,6 +184,7 @@ void qtest_quit(QTestState *s) > g_free(s->socket_path); > g_free(s->qmp_socket_path); > g_free(s->tmp_dir); > +g_free(s->incoming_uri); > } > > static void socket_sendf(int fd, const char *fmt, va_list ap) > @@ -482,3 +489,90 @@ void qtest_memwrite(QTestState *s, uint64_t addr, const > void *data, size_t size) > qtest_sendf(s, "\n"); > qtest_rsp(s, 0); > } > + > +/** > + * is_running: > + * @mch: QTestState instance to check. > + * > + * Returns 1, if mch is running, 0 if its not running. -1 means retry. > + */ > +static int is_running(QTestState *mch) > +{ > +QString *resp = qstring_new(); > +QObject *resp_obj; > +QObject *ret_obj; > +QObject *run_obj; > +int ret; > + > +resp = qstring_new(); > +qtest_qmp_resp(mch, resp, "{ 'execute': 'query-status' }", NULL); > + > +resp_obj = qobject_from_json(qstring_get_str(resp)); > +if ((!resp_obj) || (qobject_type(resp_obj) != QTYPE_QDICT)) { > +ret = -1; > +goto out; > +} > + > +ret_obj = qdict_get(qobject_to_qdict(resp_obj), "return"); > +if ((!ret_obj) || (qobject_type(ret_obj) != QTYPE_QDICT)) { > +ret = -1; > +goto out; > +} > + > +run_obj = qdict_get(qobject_to_qdict(ret_obj), "running"); > +if ((!run_obj) || (qobject_type(run_obj) != QTYPE_QBOOL)) { > +ret = -1; > +goto out; > +} > +ret = qbool_get_int(qobject_to_qbool(run_obj)); > + > +out: > +qobject_decref(resp_obj); > +QDECREF(resp); > +return ret; > +} > + > +#define SLEEP_INTERVAL 2 > +/* Abort after 2 minutes */ > +#define SLEEP_MAX (60 * 2) > + > +int test_migrate(QTe
