如何解决gnome框中的(几个) VM启动问题？
简而言之:我的虚拟机CONAN01没有在gnome框中启动，我收到/看到了不同的错误，并且不知道它们背后的真正问题是什么：
错误1:
当从Gnome桌面环境启动Gnome框并单击我的虚拟机CONAN01启动它时，我会收到一条弹出消息，其中包含打开错误日志的选项，在此错误日志中，我可以看到最后一行，状态是：

当使用终端启动gnome框，然后使用鼠标单击并运行虚拟机CONAN01时，我会收到以下错误：

• 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
Report bugs to <http://gitlab.gnome.org/gnome/gnome-boxes/issues>.
Boxes home page: <https://wiki.gnome.org/Apps/Boxes>.尽管通过使用必要的命令更改了存储池的位置，但是显示XML -配置的输出没有改变，virsh和gnome-boxes仍然认为旧位置是有效的，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，该虚拟机无法具有复杂的网络访问权限。
要么通过给qemu-bridge-helper一个setuid位来启用它：
sudo chmod 4755 /usr/lib/qemu/qemu-bridge-helper
也可以启用该文件夹中的所有可执行文件：
sudo chmod 4755 /usr/lib/qemu/*
