如何使 3D 加速在 virt-manager 中运行？

2024-6-5 • tag-icon

我正在尝试让 3D 加速在 virt-manager 中运行，但无论我在 virt-manager 中使用什么客户端，如果我启用 3D 加速，我收到这个错误。

在错误的详细信息中，有以下内容：

Error starting domain: internal error: process exited while connecting to monitor: 2023-04-14T06:53:32.967256Z qemu-system-x86_64: egl: eglInitialize failed
2023-04-14T06:53:32.967390Z qemu-system-x86_64: Failed to initialize EGL render node for SPICE GL

以下是我为 virt-manager 实例配置的设置：

视频：

<video>
  <model type="virtio" heads="1" primary="yes">
    <acceleration accel3d="yes"/>
  </model>
  <address type="pci" domain="0x0000" bus="0x00" slot="0x01" function="0x0"/>
</video>

图形类型：

<graphics type="spice">
  <listen type="none"/>
  <image compression="off"/>
  <gl enable="yes" rendernode="/dev/dri/by-path/pci-0000:05:00.0-render"/>
</graphics>

是什么egl: eglInitialize failed意思Failed to initialize EGL render node for SPICE GL？如何修复此错误？为什么会发生这种情况？我是否遗漏了重要信息？

为了确认，我已经使用以下命令检查了是否在 GRUB 中启用了虚拟化功能grep CMDLINE_LINUX_DEFAULT /etc/default/grub，结果是：

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt splash"
