如何修复 gnome-box 中的（几个）VM 启动问题？

简而言之： 我名为 CONAN01 的虚拟机未在 gnome-boxes 中启动，我收到/看到不同的错误，但不知道它们背后的真正问题是什么：

错误1：

从 Gnome 桌面环境启动 gnome-boxes 并单击虚拟机 CONAN01 启动它时，我收到一条弹出消息，其中包含打开错误日志的选项，在该错误日志中我可以看到最后几行，其中状态：

2022-06-15 09:39:22.707+0000: Domain id=1 is tainted: host-cpu
char device redirected to /dev/pts/0 (label charserial0)
2022-06-15T09:39:22.800582Z qemu-system-x86_64: warning: This family of AMD CPU doesn't support hyperthreading(2)
Please configure -smp options properly or try enabling topoext feature.
2022-06-15T10:30:56.757942Z qemu-system-x86_64: terminating on signal 15 from pid 3544 (/lib/systemd/systemd)

错误2：

当使用终端启动 gnome-boxes，然后使用鼠标单击并运行我的虚拟机 CONAN01 时，我收到以下错误：

侏儒盒子

gnome-boxes 启动时的错误输出：

(gnome-boxes:709111): Gtk-WARNING **: 22:02:27.216: GtkFlowBox with a model will ignore sort and filter functions

虚拟机 CONAN01 启动时出现错误输出：

(gnome-boxes:709111): Boxes-WARNING **: 22:02:32.045: machine.vala:605: Failed to start CONAN01: Unable to start domain: internal error: /usr/lib/qemu/qemu-bridge-helper --use-vnet --br=virbr0 --fd=31: failed to communicate with bridge helper: Transport endpoint is not connected
stderr=failed to create tun device: Operation not permitted

错误3：

当执行 gnome-boxes – CLI 通过执行必要的命令进行检查时，我收到以下信息：

gnome-boxes --检查

信息输出：

(gnome-boxes:717997): Boxes-WARNING **: 22:50:30.599: util-app.vala:376: Failed to execute child process ?restorecon? (No such file or directory)
• The CPU is capable of virtualization: yes
• The KVM module is loaded: yes
• Libvirt KVM guest available: yes
• Boxes storage pool available: no
    /root/.local/share/gnome-boxes/images is known to libvirt as GNOME Boxes’s storage pool but this directory does not exist
• The SELinux context is default: no

尽管使用必要的命令更改了存储池的位置，但显示 XML 的输出 - 配置没有更改，virsh 和 gnome-boxes 仍然认为旧位置有效，我的意图是更改“/home/myusername/” .local/share/gnome-boxes/images”：

解决方案是在 qemu 实例 qemu:///session 上启用网络，因为gnome-boxes在该实例上创建虚拟机，默认情况下无法进行复杂的网络访问。

通过提供qemu-bridge-helpersetuid 位来启用它：

sudo chmod 4755 /usr/lib/qemu/qemu-bridge-helper

或者您可以启用该文件夹中的所有可执行文件：

sudo chmod 4755 /usr/lib/qemu/*

可以在这里和这里找到更复杂的信息：
