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);
}
}

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);
}
netdev_init_modern()
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：
