前言

本文以 QEMU 8.2.2 为例，分析其作为系统仿真工具的工作过程，并为读者展示各种 QEMU 系统仿真的启动配置实例。
本文读者需要具备一定的 QEMU 系统仿真使用经验，并对 C 语言编程有一定了解。

---

一、QEMU是什么？

QEMU 是一个通用且开源的机器模拟器和虚拟机。
其官方主页是：https://www.qemu.org/

---

二、QEMU系统仿真的机器创建分析实例

1.系统仿真的命令行参数

QEMU 作为系统仿真工具，其入口代码在 system/main.c 文件中，初始化函数 qemu_init() 的实现在 system/vl.c 文件中。
前文完成创建目标机器的过程分析，本文将继续后续运行过程的分析，读者需要对 QEMU 系统启动过程的程序代码有所了解，相关内容可以参考《QEMU系统分析之启动篇》系列文章。

..\qemu\8.2.2-qkd\qemu-system-x86_64.exe -cpu "Penryn" -M  "q35,accel=whpx,smm=off" -m "6G" -display "sdl" -audio "sdl,model=hda" -vga "std" -L "data"

---

2.创建后期后端驱动

这部分代码在 system/vl.c 文件中，实现如下：

int qemu_init(int argc, char **argv)
{
.../** Beware, QOM objects created before this point miss global and* compat properties.** Global properties get set up by qdev_prop_register_global(),* called from user_register_global_props(), and certain option* desugaring.  Also in CPU feature desugaring (buried in* parse_cpu_option()), which happens below this point, but may* only target the CPU type, which can only be created after* parse_cpu_option() returned the type.** Machine compat properties: object_set_machine_compat_props().* Accelerator compat props: object_set_accelerator_compat_props(),* called from do_configure_accelerator().*/machine_class = MACHINE_GET_CLASS(current_machine);if (!qtest_enabled() && machine_class->deprecation_reason) {warn_report("Machine type '%s' is deprecated: %s",machine_class->name, machine_class->deprecation_reason);}/** Create backends before creating migration objects, so that it can* check against compatibilities on the backend memories (e.g. postcopy* over memory-backend-file objects).*/qemu_create_late_backends();
...
}

前文分析了加速器的配置过程，本文继续完成创建后期后端驱动的过程。
主函数中，如果设置了设置的机器类有已弃用原因的，在终端输出弃用原因来提醒用户。
然后，创建后期后端驱动。

qemu_create_late_backends()

函数 qemu_create_late_backends() 代码如下：

static void qemu_create_late_backends(void)
{if (qtest_chrdev) {qtest_server_init(qtest_chrdev, qtest_log, &error_fatal);}net_init_clients();object_option_foreach_add(object_create_late);if (tpm_init() < 0) {exit(1);}qemu_opts_foreach(qemu_find_opts("mon"),mon_init_func, NULL, &error_fatal);if (foreach_device_config(DEV_SERIAL, serial_parse) < 0)exit(1);if (foreach_device_config(DEV_PARALLEL, parallel_parse) < 0)exit(1);if (foreach_device_config(DEV_DEBUGCON, debugcon_parse) < 0)exit(1);/* now chardevs have been created we may have semihosting to connect */qemu_semihosting_chardev_init();
}

首先，如果命令行参数中有 “-qtest” 则调用函数 qtest_server_init() 做配置。

---

qtest_server_init()

代码如下：

void qtest_server_init(const char *qtest_chrdev, const char *qtest_log, Error **errp)
{ERRP_GUARD();Chardev *chr;Object *qobj;chr = qemu_chr_new("qtest", qtest_chrdev, NULL);if (chr == NULL) {error_setg(errp, "Failed to initialize device for qtest: \"%s\"",qtest_chrdev);return;}qobj = object_new(TYPE_QTEST);object_property_set_str(qobj, "chardev", chr->label, &error_abort);if (qtest_log) {object_property_set_str(qobj, "log", qtest_log, &error_abort);}object_property_add_child(qdev_get_machine(), "qtest", qobj);user_creatable_complete(USER_CREATABLE(qobj), errp);if (*errp) {object_unparent(qobj);}object_unref(OBJECT(chr));object_unref(qobj);
}

首先，调用

    chr = qemu_chr_new("qtest", qtest_chrdev, NULL);

新建字符设备，函数 qemu_chr_new() 如下：

static Chardev *qemu_chr_new_permit_mux_mon(const char *label,const char *filename,bool permit_mux_mon,GMainContext *context)
{Chardev *chr;chr = qemu_chr_new_noreplay(label, filename, permit_mux_mon, context);if (chr) {if (replay_mode != REPLAY_MODE_NONE) {qemu_chr_set_feature(chr, QEMU_CHAR_FEATURE_REPLAY);}if (qemu_chr_replay(chr) && CHARDEV_GET_CLASS(chr)->chr_ioctl) {error_report("Replay: ioctl is not supported ""for serial devices yet");}replay_register_char_driver(chr);}return chr;
}Chardev *qemu_chr_new(const char *label, const char *filename,GMainContext *context)
{return qemu_chr_new_permit_mux_mon(label, filename, false, context);
}

继续跟踪进入函数 qemu_chr_new_noreplay() ，代码如下：

Chardev *qemu_chr_new_noreplay(const char *label, const char *filename,bool permit_mux_mon, GMainContext *context)
{const char *p;Chardev *chr;QemuOpts *opts;Error *err = NULL;if (strstart(filename, "chardev:", &p)) {return qemu_chr_find(p);}opts = qemu_chr_parse_compat(label, filename, permit_mux_mon);if (!opts)return NULL;chr = qemu_chr_new_from_opts(opts, context, &err);if (!chr) {error_report_err(err);goto out;}if (qemu_opt_get_bool(opts, "mux", 0)) {assert(permit_mux_mon);monitor_init_hmp(chr, true, &err);if (err) {error_report_err(err);object_unparent(OBJECT(chr));chr = NULL;goto out;}}out:qemu_opts_del(opts);return chr;
}

在函数中，将调用 qemu_chr_parse_compat() 来解析命令行参数，函数 qemu_chr_parse_compat() 代码如下：

QemuOpts *qemu_chr_parse_compat(const char *label, const char *filename,bool permit_mux_mon)
{char host[65], port[33], width[8], height[8];int pos;const char *p;QemuOpts *opts;Error *local_err = NULL;opts = qemu_opts_create(qemu_find_opts("chardev"), label, 1, &local_err);if (local_err) {error_report_err(local_err);return NULL;}if (strstart(filename, "mon:", &p)) {if (!permit_mux_mon) {error_report("mon: isn't supported in this context");return NULL;}filename = p;qemu_opt_set(opts, "mux", "on", &error_abort);if (strcmp(filename, "stdio") == 0) {/* Monitor is muxed to stdio: do not exit on Ctrl+C by default* but pass it to the guest.  Handle this only for compat syntax,* for -chardev syntax we have special option for this.* This is what -nographic did, redirecting+muxing serial+monitor* to stdio causing Ctrl+C to be passed to guest. */qemu_opt_set(opts, "signal", "off", &error_abort);}}if (strcmp(filename, "null")    == 0 ||strcmp(filename, "pty")     == 0 ||strcmp(filename, "msmouse") == 0 ||strcmp(filename, "wctablet") == 0 ||strcmp(filename, "braille") == 0 ||strcmp(filename, "testdev") == 0 ||strcmp(filename, "stdio")   == 0) {qemu_opt_set(opts, "backend", filename, &error_abort);return opts;}if (strstart(filename, "vc", &p)) {qemu_opt_set(opts, "backend", "vc", &error_abort);if (*p == ':') {if (sscanf(p+1, "%7[0-9]x%7[0-9]", width, height) == 2) {/* pixels */qemu_opt_set(opts, "width", width, &error_abort);qemu_opt_set(opts, "height", height, &error_abort);} else if (sscanf(p+1, "%7[0-9]Cx%7[0-9]C", width, height) == 2) {/* chars */qemu_opt_set(opts, "cols", width, &error_abort);qemu_opt_set(opts, "rows", height, &error_abort);} else {goto fail;}}return opts;}if (strcmp(filename, "con:") == 0) {qemu_opt_set(opts, "backend", "console", &error_abort);return opts;}if (strstart(filename, "COM", NULL)) {qemu_opt_set(opts, "backend", "serial", &error_abort);qemu_opt_set(opts, "path", filename, &error_abort);return opts;}if (strstart(filename, "file:", &p)) {qemu_opt_set(opts, "backend", "file", &error_abort);qemu_opt_set(opts, "path", p, &error_abort);return opts;}if (strstart(filename, "pipe:", &p)) {qemu_opt_set(opts, "backend", "pipe", &error_abort);qemu_opt_set(opts, "path", p, &error_abort);return opts;}if (strstart(filename, "tcp:", &p) ||strstart(filename, "telnet:", &p) ||strstart(filename, "tn3270:", &p) ||strstart(filename, "websocket:", &p)) {if (sscanf(p, "%64[^:]:%32[^,]%n", host, port, &pos) < 2) {host[0] = 0;if (sscanf(p, ":%32[^,]%n", port, &pos) < 1)goto fail;}qemu_opt_set(opts, "backend", "socket", &error_abort);qemu_opt_set(opts, "host", host, &error_abort);qemu_opt_set(opts, "port", port, &error_abort);if (p[pos] == ',') {if (!qemu_opts_do_parse(opts, p + pos + 1, NULL, &local_err)) {error_report_err(local_err);goto fail;}}if (strstart(filename, "telnet:", &p)) {qemu_opt_set(opts, "telnet", "on", &error_abort);} else if (strstart(filename, "tn3270:", &p)) {qemu_opt_set(opts, "tn3270", "on", &error_abort);} else if (strstart(filename, "websocket:", &p)) {qemu_opt_set(opts, "websocket", "on", &error_abort);}return opts;}if (strstart(filename, "udp:", &p)) {qemu_opt_set(opts, "backend", "udp", &error_abort);if (sscanf(p, "%64[^:]:%32[^@,]%n", host, port, &pos) < 2) {host[0] = 0;if (sscanf(p, ":%32[^@,]%n", port, &pos) < 1) {goto fail;}}qemu_opt_set(opts, "host", host, &error_abort);qemu_opt_set(opts, "port", port, &error_abort);if (p[pos] == '@') {p += pos + 1;if (sscanf(p, "%64[^:]:%32[^,]%n", host, port, &pos) < 2) {host[0] = 0;if (sscanf(p, ":%32[^,]%n", port, &pos) < 1) {goto fail;}}qemu_opt_set(opts, "localaddr", host, &error_abort);qemu_opt_set(opts, "localport", port, &error_abort);}return opts;}if (strstart(filename, "unix:", &p)) {qemu_opt_set(opts, "backend", "socket", &error_abort);if (!qemu_opts_do_parse(opts, p, "path", &local_err)) {error_report_err(local_err);goto fail;}return opts;}if (strstart(filename, "/dev/parport", NULL) ||strstart(filename, "/dev/ppi", NULL)) {qemu_opt_set(opts, "backend", "parallel", &error_abort);qemu_opt_set(opts, "path", filename, &error_abort);return opts;}if (strstart(filename, "/dev/", NULL)) {qemu_opt_set(opts, "backend", "serial", &error_abort);qemu_opt_set(opts, "path", filename, &error_abort);return opts;}error_report("'%s' is not a valid char driver", filename);fail:qemu_opts_del(opts);return NULL;
}

对于 qtest 的服务器端的实现，我们通常选用 telnet 或 unix 的 socket 后端驱动来实现。

一个参考的命令行参数例子如下：

 -qtest "unix:qtest-sock,server,nowait"

至此，qtest_server_init() 的执行路径已经清晰了，接下来继续主程序的运行，进入函数 net_init_clients() 中。

---

net_init_clients()

代码如下：

void net_init_clients(void)
{net_change_state_entry =qemu_add_vm_change_state_handler(net_vm_change_state_handler, NULL);QTAILQ_INIT(&net_clients);netdev_init_modern();qemu_opts_foreach(qemu_find_opts("netdev"), net_init_netdev, NULL,&error_fatal);qemu_opts_foreach(qemu_find_opts("nic"), net_param_nic, NULL,&error_fatal);qemu_opts_foreach(qemu_find_opts("net"), net_init_client, NULL,&error_fatal);
}

---

代码如下：

static void netdev_init_modern(void)
{while (!QSIMPLEQ_EMPTY(&nd_queue)) {NetdevQueueEntry *nd = QSIMPLEQ_FIRST(&nd_queue);QSIMPLEQ_REMOVE_HEAD(&nd_queue, entry);loc_push_restore(&nd->loc);net_client_init1(nd->nd, true, &error_fatal);loc_pop(&nd->loc);qapi_free_Netdev(nd->nd);g_free(nd);}
}

---

net_init_netdev()

代码如下：

static int net_init_netdev(void *dummy, QemuOpts *opts, Error **errp)
{const char *type = qemu_opt_get(opts, "type");if (type && is_help_option(type)) {show_netdevs();exit(0);}return net_client_init(opts, true, errp);
}

---

net_param_nic()

代码如下：

/* For the convenience "--nic" parameter */
static int net_param_nic(void *dummy, QemuOpts *opts, Error **errp)
{char *mac, *nd_id;int idx, ret;NICInfo *ni;const char *type;type = qemu_opt_get(opts, "type");if (type) {if (g_str_equal(type, "none")) {return 0;    /* Nothing to do, default_net is cleared in vl.c */}if (is_help_option(type)) {GPtrArray *nic_models = qemu_get_nic_models(TYPE_DEVICE);show_netdevs();printf("\n");qemu_show_nic_models(type, (const char **)nic_models->pdata);g_ptr_array_free(nic_models, true);exit(0);}}idx = nic_get_free_idx();if (idx == -1 || nb_nics >= MAX_NICS) {error_setg(errp, "no more on-board/default NIC slots available");return -1;}if (!type) {qemu_opt_set(opts, "type", "user", &error_abort);}ni = &nd_table[idx];memset(ni, 0, sizeof(*ni));ni->model = qemu_opt_get_del(opts, "model");/* Create an ID if the user did not specify one */nd_id = g_strdup(qemu_opts_id(opts));if (!nd_id) {nd_id = id_generate(ID_NET);qemu_opts_set_id(opts, nd_id);}/* Handle MAC address */mac = qemu_opt_get_del(opts, "mac");if (mac) {ret = net_parse_macaddr(ni->macaddr.a, mac);g_free(mac);if (ret) {error_setg(errp, "invalid syntax for ethernet address");goto out;}if (is_multicast_ether_addr(ni->macaddr.a)) {error_setg(errp, "NIC cannot have multicast MAC address");ret = -1;goto out;}}qemu_macaddr_default_if_unset(&ni->macaddr);ret = net_client_init(opts, true, errp);if (ret == 0) {ni->netdev = qemu_find_netdev(nd_id);ni->used = true;nb_nics++;}out:g_free(nd_id);return ret;
}

---

net_init_client()

代码如下：

static int net_client_init(QemuOpts *opts, bool is_netdev, Error **errp)
{gchar **substrings = NULL;Netdev *object = NULL;int ret = -1;Visitor *v = opts_visitor_new(opts);/* Parse convenience option format ipv6-net=fec0::0[/64] */const char *ip6_net = qemu_opt_get(opts, "ipv6-net");if (ip6_net) {char *prefix_addr;unsigned long prefix_len = 64; /* Default 64bit prefix length. */substrings = g_strsplit(ip6_net, "/", 2);if (!substrings || !substrings[0]) {error_setg(errp, QERR_INVALID_PARAMETER_VALUE, "ipv6-net","a valid IPv6 prefix");goto out;}prefix_addr = substrings[0];/* Handle user-specified prefix length. */if (substrings[1] &&qemu_strtoul(substrings[1], NULL, 10, &prefix_len)){error_setg(errp,"parameter 'ipv6-net' expects a number after '/'");goto out;}qemu_opt_set(opts, "ipv6-prefix", prefix_addr, &error_abort);qemu_opt_set_number(opts, "ipv6-prefixlen", prefix_len,&error_abort);qemu_opt_unset(opts, "ipv6-net");}/* Create an ID for -net if the user did not specify one */if (!is_netdev && !qemu_opts_id(opts)) {qemu_opts_set_id(opts, id_generate(ID_NET));}if (visit_type_Netdev(v, NULL, &object, errp)) {ret = net_client_init1(object, is_netdev, errp);}qapi_free_Netdev(object);out:g_strfreev(substrings);visit_free(v);return ret;
}static int net_init_client(void *dummy, QemuOpts *opts, Error **errp)
{return net_client_init(opts, false, errp);
}

3.调试输出

首先，添加跟踪调试信息，修改后的代码如下：

static int do_configure_accelerator(void *opaque, QemuOpts *opts, Error **errp)
{
...accel = ACCEL(object_new_with_class(OBJECT_CLASS(ac)));HUEDBG("accel=0x%llx\n", (unsigned long long int)accel);huedbg_dump_AccelClass(ac, 9);
...
}static void configure_accelerators(const char *progname)
{
...HUEDBG("accelerators=[%s]\n", accelerators);accel_list = g_strsplit(accelerators, ":", 0);
...
}int accel_init_machine(AccelState *accel, MachineState *ms)
{AccelClass *acc = ACCEL_GET_CLASS(accel);int ret;HUEDBG("accel=0x%llx\n", (unsigned long long int)accel);ms->accelerator = accel;*(acc->allowed) = true;ret = acc->init_machine(ms);if (ret < 0) {HUEDBG("\n");ms->accelerator = NULL;*(acc->allowed) = false;object_unref(OBJECT(accel));} else {HUEDBG("\n");object_set_accelerator_compat_props(acc->compat_props);}huedbg_dump_AccelClass(acc, 9);return ret;
}int qemu_init(int argc, char **argv)
{
.../** Note: uses machine properties such as kernel-irqchip, must run* after qemu_apply_machine_options.*/huedbg_flag = 1;HUEDBG("\n");configure_accelerators(argv[0]);HUEDBG("\n");huedbg_flag = 0;phase_advance(PHASE_ACCEL_CREATED);
...
}

运行后，输出信息如下：
