操作系统与启动设置#

1
<os>
2
  <type arch='x86_64' machine='pc-q35-6.2'>hvm</type>
3
  <loader readonly='yes' type='pflash'>/usr/share/edk2/ovmf/OVMF.fd</loader>
4
  <nvram template='/usr/share/edk2/ovmf/OVMF.fd'>/var/lib/libvirt/qemu/nvram/578625568c7e41ccb827ecb9e01e3460.fd</nvram>
5
  <bootmenu enable='yes'/>
6
  <smbios mode='sysinfo'/>
7
</os>

<os>: 操作系统相关配置。
<type>:
- arch=‘x86_64’: 目标CPU架构。
- machine=‘pc-q35-6.2’: 模拟的机器类型（主板型号）。
  - q35:较新的平台，模拟的是 Intel 的 Q35 芯片组，支持更多现代特性。提供更好的硬件虚拟化支持，例如更好的 PCIe 设备支持、SATA 和更高效的内存管理。支持 UEFI 启动，适合运行现代操作系统，尤其是 Windows 10、Windows 11 或 Linux 现代发行版。
  - i440fx:老旧平台，类似于早期的 Intel 440FX 芯片组。它支持较老的硬件和设备模型，兼容性较强，适合运行较旧的操作系统或软件（比如 Windows XP、Windows 7 等）。适合需要较低兼容性要求的系统。
- hvm: 完全虚拟化。
<loader>: UEFI固件文件路径，readonly=‘yes’表示使用只读副本。
<nvram>: UEFI变量存储文件路径，基于模板创建。 legacy引导模式的虚拟机无上述两项标签
<bootmenu enable='yes'/>: 启动时显示引导菜单。类似以下界面
<smbios mode='sysinfo'/>: 使用上面<sysinfo>标签中定义的SMBIOS信息。

虚拟硬件特性#

1
<features>
2
  <acpi/>
3
  <apic/>
4
  <pae/>
5
  <ioapic driver='kvm'/>
6
</features>

<features>: 启用虚拟硬件的ACPI（电源管理）、APIC（高级可编程中断控制器）、PAE（物理地址扩展）等特性。ioapic driver=‘kvm’指定使用KVM的内置I/O APIC。

CPU模型与特性#

1
<cpu mode='custom' match='exact' check='full'>
2
  <model fallback='forbid'>qemu64</model>
3
  <topology sockets='1' dies='1' clusters='1' cores='4' threads='1'/>
4
  <feature policy='require' name='x2apic'/>
5
  <feature policy='require' name='hypervisor'/>
6
  <feature policy='require' name='lahf_lm'/>
7
  <feature policy='disable' name='svm'/>
8
</cpu>

<cpu>: 详细的CPU模拟配置。
- mode=‘custom’ match=‘exact’: 严格匹配自定义的CPU模型。与云主机的设置的CPU模式有关
  - 兼容模式：custom
  - 物理机匹配模式：host-model
  - 直通模式：host-passthrough
  - 云平台修改CPU模式，兼容模式和物理机匹配模式在/run/libvirt/qemu/UUID.xml(使用dumpxml指令查看的也是该文件，该文件为云主机运行时的配置)均显示为custom；但云主机的实际配置/etc/libvirt/qemu/UUID.xml(该文件为云主机持久化的配置文件，也就是定义配置文件)正常显示为对应的模式；预配置的是host-model（模拟与宿主机CPU功能集兼容的虚拟CPU），但是实际启动的时候，会生成一个自定义CPU配置（即custom模式），其中包含与宿主机兼容的特性子集。如下图
- check=‘full’: 进行完整的CPU特性兼容性检查。
<model fallback='forbid'>qemu64</model>: 使用qemu64基础CPU模型，如果主机不支持则禁止启动（fallback=‘forbid’）。
<topology>: CPU拓扑结构：1个插槽，4个核心，单线程。
<feature>: 明确要求或禁用特定的CPU特性。例如，禁用了AMD的SVM虚拟化扩展。
