I tried to add some more fprintfs here and there to see where it hangs, but I did not succeed to get any further. However, the CI build succeeds with this fix instead: diff a/tests/qtest/vhost-user-test.c b/tests/qtest/vhost-user-test.c --- a/tests/qtest/vhost-user-test.c +++ b/tests/qtest/vhost-user-test.c @@ -707,9 +707,9 @@ static void test_read_guest_mem(void *obj, void *arg, QGuestAllocator *alloc) static void test_migrate(void *obj, void *arg, QGuestAllocator *alloc) { TestServer *s = arg; - TestServer *dest = test_server_new("dest"); - GString *dest_cmdline = g_string_new(qos_get_current_command_line()); - char *uri = g_strdup_printf("%s%s", "unix:", dest->mig_path); + TestServer *dest; + GString *dest_cmdline; + char *uri; QTestState *to; GSource *source; QDict *rsp; @@ -720,6 +720,10 @@ static void test_migrate(void *obj, void *arg, QGuestAllocator *alloc) return; } + dest = test_server_new("dest"); + dest_cmdline = g_string_new(qos_get_current_command_line()); + uri = g_strdup_printf("%s%s", "unix:", dest->mig_path); + size = get_log_size(s); g_assert_cmpint(size, ==, (256 * 1024 * 1024) / (VHOST_LOG_PAGE * 8)); @@ -778,6 +782,7 @@ static void test_migrate(void *obj, void *arg, QGuestAllocator *alloc) qtest_quit(to); test_server_free(dest); g_free(uri); + g_string_free(dest_cmdline, true); } Here's a build with that patch that succeeded: https://gitlab.com/huth/qemu/-/jobs/405357307 So if you agree with that patch, I think we should simply use that version instead, ok?
