00088112000i[      ] restoring default signal behavior
========================================================================
Bochs is exiting with the following message:
[SDL2  ] User requested shutdown.
========================================================================
00088112000i[SIM   ] quit_sim called with exit code 1
 

现在，我们来详细解读一下上面的 Bochs 启动日志。上面的 Bochs 启动日志 显示了 Bochs 在尝试启动一个基于 /etc/bochsrc 配置文件的虚拟机时失败的过程。

​总体流程和最终结果：​​

Bochs 启动 -> 加载配置和插件 -> 初始化硬件（CPU、内存、各种 PCI 设备如 IDE、USB、声卡、网卡、VGA 等）-> BIOS 执行自检和初始化 -> ​VGA 初始化失败​ -> BIOS 报告无启动设备并可能尝试从软盘启动 -> 最终 Bochs 因内部错误或 BIOS 请求而退出。

​逐段解析 (以第一份日志为主，两份内容高度一致)：​​

  1. ​Bochs 启动和基本信息：​​

    • sudo bochs -f /etc/bochsrc -q: 使用 sudo 权限，指定配置文件 /etc/bochsrc，-q 表示安静模式（减少一些非必要输出，但这里输出依然很多，因为是启动过程）。
    • LTDL_LIBRARY_PATH not set. using compile time default...: Bochs 找不到用户设置的库路径，使用编译时的默认路径。
    • Bochs x86 Emulator 3.0.devel ... Compiled on Oct 29 2025 ...: 显示 Bochs 版本信息，这是一个开发版，编译日期是 2025 年（对于当前时间来说是未来，表明这可能是一个特定构建或示例时间戳）。
    • BXSHARE not set. using compile time default ...: 类似地，使用编译时的共享数据路径。
    • lt_dlhandle is ... loaded plugin ...: Bochs 动态加载了一系列插件，这些插件提供了对不同硬件的仿真支持，例如：
      • libbx_parallel.so (并口)
      • libbx_gameport.so (游戏端口)
      • libbx_speaker.so (PC 喇叭)
      • libbx_biosdev.so (BIOS 设备)
      • libbx_unmapped.so (未映射的 I/O 空间)
      • libbx_extfpuirq.so (扩展 FPU 中断请求)
      • libbx_serial.so (串口)
      • libbx_sb16.so (Sound Blaster 16 声卡)
      • libbx_textconfig.so (文本配置界面支持)
      • libbx_sdl2_gui.so (使用 SDL2 作为图形界面)

  2. ​SDL2 GUI 初始化：​​

    • installing sdl2 module as the Bochs GUI: 确认将使用 SDL2 模块作为图形用户界面。
    • maximum host resolution: x=4096 y=2160: SDL2 报告主机支持的最大分辨率。

  3. ​系统配置信息摘要：​​

    • 显示了模拟的系统配置，如处理器数量、A20 地址线支持、IPS (每秒指令数)、CPU 配置 (使用预定义的 corei7_haswell_4770 模型)、优化选项、设备配置 (PCI、网络、声卡、USB、VGA 扩展支持)。

  4. ​磁盘和模块信息：​​

    • Disk image modules: 列出支持的磁盘镜像格式。
    • Networking modules: 列出支持的网络设备。
    • Sound drivers: 列出支持的声卡驱动。
    • Pluggable USB devices: 列出支持的 USB 设备类型。

  5. ​插件初始化细节：​​

    • 大量 PLUGIN init_dev of ... by virtual method 和 PLUGIN reset of ... by virtual method：这是 Bochs 对每个加载的插件设备进行初始化和重置。每个设备都会报告其状态。
    • 关键设备初始化：
      • pci: i440FX 主板芯片组。
      • pci2isa: PIIX3 PCI 到 ISA 桥接芯片。
      • cmos: CMOS 芯片，用于存储 BIOS 设置和实时时钟。Using local time for initial clock 表示使用本地时间初始化。
      • dma, pic, pit: DMA 控制器、可编程中断控制器、可编程间隔定时器。
      • vga: VGA 显卡。BXVGA ] VBE Bochs Display Extension Enabled (16 MB) 表示启用了 VBE (VESA BIOS Extensions)。
      • floppy: 软驱。fd0: '/os/sources/hucos/hucos.img' 指定了软盘镜像文件。Using boot sequence floppy, none, none 设置软驱为第一启动设备。
      • acpi, hpet: ACPI 和 HPET (高精度事件定时器)。
      • ioapic: I/O APIC (高级可编程中断控制器)。
      • keyboard: 键盘。
      • pci_ide: PCI IDE 控制器。
      • harddrv: 硬盘驱动器 (虽然日志里没明确列出硬盘镜像，但配置文件中可能有，或者这里指的是 IDE 控制器本身)。
      • sb16: Sound Blaster 16 声卡初始化细节。

  6. ​CPU 重置和识别：​​

    • SYS bx_pc_system_c::Reset(HARDWARE) called: 系统调用硬件重置。
    • CPU0 cpu hardware reset: CPU 0 被重置。
    • 接下来是一长串 CPUID 指令的输出，显示了模拟的 CPU (corei7_haswell_4770) 的特性和支持的指令集。例如 SSE, SSE2, AVX, AVX2 等。
    • WARNING: RDRAND would not produce true random numbers !: 如果 Bochs 没有使用宿主机的真随机源，RDRAND 指令可能不会产生真正的随机数。

  7. ​BIOS 执行阶段：​​

    • BIOS BUILD DATE: 05/15/25: 启动的 ROM BIOS 镜像的构建日期。
    • Starting rombios32: 开始执行 ROM BIOS 32位代码。
    • ram_size=0x10000000 (256MB), ram_end=256MB: 报告检测到的内存大小。
    • Found 1 cpu(s): 检测到 1 个 CPU。
    • PCI 设备枚举：PCI: bus=0 devfn=... vendor_id=... device_id=... class=...。这里可以看到模拟的 i440FX (主机桥) 和 PIIX3 (PCI-to-ISA 桥) 等设备。
    • PIIX3/PIIX4 init: elcr=00 0a: 初始化 PIIX4 的 ELCR (可编程中断控制器) 寄存器。
    • ACPI tables: RSDP addr=... ACPI DATA addr=...: 报告 ACPI 表的地址。

  8. ​致命错误：VGA 初始化失败​

    • Start SeaVGABIOS (version 1.13.0...): Bochs 尝试启动其内置的 SeaVGABIOS。
    • enter vga_post:: 进入 VGA 的 POST (加电自检) 程序。
    • cirrus init: 尝试初始化模拟的 Cirrus Logic VGA 硬件。
    • ​**00001531012i[BIOS ] Failed to initialize VGA hardware. Exiting.: ​这是导致启动失败的核心错误。​**​ BIOS 无法初始化模拟的 Cirrus VGA 显卡。

  9. ​启动失败的后续：​​

    • 00013629458i[BIOS ] int13_harddisk: function 02, unmapped device for ELDL=80: 由于 VGA 初始化失败，系统可能处于不稳定状态。BIOS 尝试从硬盘 (ELDL=80 通常指第一个硬盘) 读取扇区 (INT 13h, AH=02h)，但设备未映射或不可用。这可能是因为系统在 VGA 初始化失败后提早中止了正常的启动流程，或者 BIOS 认为没有可用的显示设备，从而无法继续。
    • 00013634154p[BIOS ] >>PANIC<< No bootable device.: BIOS 检测到没有可启动的设备。这很可能是 VGA 初始化失败导致的连锁反应，因为没有显示输出，系统可能认为无法正常引导，或者 BIOS 自身在检测到关键硬件（如显示适配器）初始化失败后，就判定为无启动设备。
    • 接下来是 CPU 寄存器和状态的转储，显示 CPU 处于实模式。

  10. ​Bochs 退出：​​

    • 00088112000i[CMOS ] Last time: ...: 记录 CMOS 时间。
    • 00088112000i[ ] restoring default signal behavior: 恢复默认的信号处理。
    • ========================================================================
    • Bochs is exiting with the following message: [SDL2 ] User requested shutdown.: Bochs 退出，并报告 "用户请求关闭"。在这种情况下，这通常意味着模拟环境中发生了严重错误（如 BIOS 报告的 "No bootable device" 或更早的 VGA 初始化失败），导致模拟的操作系统或 BIOS 请求了一个关机或复位，Bochs 据此终止运行。
    • 00088112000i[SIM ] quit_sim called with exit code 1: 模拟器核心被要求退出，返回码为 1 (通常表示错误)。

​总结与可能原因：​​

  1. ​主要问题：VGA 初始化失败。​​ Failed to initialize VGA hardware. Exiting.
    • 这通常指向模拟的 Cirrus Logic VGA 显卡或其 BIOS (vgabios-cirrus.bin-1.13.0，从日志中的路径 /usr/local/share/bochs/vgabios-cirrus.bin-1.13.0 可以推断) 存在问题。
  2. ​次要问题：无启动设备。​​ [BIOS ] No bootable device.
    • 这是 VGA 初始化失败后的结果。因为没有图形输出，或者 BIOS 在 VGA 初始化失败后进入了错误状态，它无法或认为不应该继续尝试从软盘 (hucos.img) 启动。
  3. ​Bochs 报告 "User requested shutdown"：​​
    • 这是 Bochs 对内部致命错误的最终处理方式，而不是字面上的用户按下了关机键。它响应了 BIOS 层面的失败。

​可能的解决方案/排查方向：​​

  1. ​检查 Cirrus VGA BIOS 文件：​​
    • 确认 /usr/local/share/bochs/vgabios-cirrus.bin-1.13.0 文件存在且没有损坏。可以尝试重新下载或从其他来源获取这个 BIOS 文件。
  2. ​更新 Bochs：​​
    • 你使用的 Bochs 是 3.0.devel，可能存在已知的 VGA 模拟 bug。尝试更新到最新的稳定版本或开发版本。
  3. ​Bochs 编译选项：​​
    • 日志中提到了 --enable-vmx=2 的警告，但这通常不影响基本的 VGA 模拟。不过，确保 Bochs 是完整编译的。
  4. ​尝试不同的 VGA 模式/ROM (如果可能)：​​
    • 虽然 Bochs 通常捆绑特定的 VGA ROM，但如果配置允许或有其他途径，可以尝试不同的 VGA 兼容模式或 ROM (例如，标准 VGA 或其他模拟的显卡类型，如果你的配置和目标系统支持)。但在你的配置中，似乎是明确使用了 Cirrus。
  5. ​简化配置测试：​​
    • 作为调试步骤，可以尝试一个非常简单的 Bochs 配置，只包含最基本的硬件（CPU、内存、一个软驱、一个基本的 VGA），看是否能启动。如果能，再逐步添加回你的配置项。
  6. ​查看 Bochs 社区/bug追踪器：​​
    • 搜索是否有其他人遇到过相同版本的 Bochs 和类似的 "Failed to initialize VGA hardware" 错误。

总的来说，这个日志清晰地指出了启动失败发生在 BIOS 尝试初始化模拟的 Cirrus VGA 显卡时。解决这个 VGA 初始化问题是让虚拟机继续启动的关键。

注：本次启动失败的重要原因，在于 选择了不合适的 vgabios 镜像，更换为 更为合适的 vgabios 镜像后，问题即可解决！例如：vgaromimage: file=/usr/local/share/bochs/VGABIOS-lgpl-latest.bin ，如需在 bochs3.0 devel 启动时，即进入调试模式，可以通过如下方式启动：

sudo bochs -f /etc/bochsrc -debugger -q
