From a3c0ebc9b09cb15cac35690412eb66aaa5eb4f23 Mon Sep 17 00:00:00 2001 From: Fabiano Rosas Date: Wed, 18 Oct 2023 16:27:34 -0300 Subject: tests/qtest: Introduce qtest_resolve_machine_alias The migration tests are being enhanced to test migration between different QEMU versions. A requirement of migration is that the machine type between source and destination matches, including the version. We cannot hardcode machine types in the tests because those change with each release. QEMU provides a machine type alias that has a fixed name, but points to the latest machine type at each release. Add a helper to resolve the alias into the exact machine type. E.g. "-machine pc" resolves to "pc-i440fx-8.2" Reviewed-by: Juan Quintela Reviewed-by: Thomas Huth Signed-off-by: Fabiano Rosas Signed-off-by: Juan Quintela Message-ID: <20231018192741.25885-6-farosas@suse.de> --- tests/qtest/libqtest.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'tests/qtest/libqtest.c') diff --git a/tests/qtest/libqtest.c b/tests/qtest/libqtest.c index 603d900e7d..c843c41188 100644 --- a/tests/qtest/libqtest.c +++ b/tests/qtest/libqtest.c @@ -1565,6 +1565,22 @@ void qtest_cb_for_every_machine(void (*cb)(const char *machine), } } +char *qtest_resolve_machine_alias(const char *var, const char *alias) +{ + struct MachInfo *machines; + int i; + + machines = qtest_get_machines(var); + + for (i = 0; machines[i].name != NULL; i++) { + if (machines[i].alias && g_str_equal(alias, machines[i].alias)) { + return g_strdup(machines[i].name); + } + } + + return NULL; +} + bool qtest_has_machine_with_env(const char *var, const char *machine) { struct MachInfo *machines; -- cgit 1.4.1
