我在 Fedora 27 主机上创建了一个 Fedora 27 来宾，添加了 2 个文件系统共享，在 guest/s fstab 中添加了条目，启动，一切正常。但是，当我尝试从主机“d_drive”添加另一个驱动器/安装时，出现以下错误，并且我不确定如何对其进行故障排除。据我所知，工作共享与有问题的 d_drive 具有相同的用户所有权和权限，并且从一个简单的“getfacl”来看，这些权限看起来也几乎相同，减去标志（我不明白）。
我从哪里/如何开始解决这个问题？
系统信息：

当我尝试启动域时，从 virt-manager gui 中：

这可能不是全部，但它似乎有效（显然我已经有了第一个命令......）。
