我已通过 homebrew 在 Mac OS X 10.11.5 上安装了 virt-manager 1.3.2。当我尝试连接到在另一台机器 192.168.1.70 上运行的远程 libvirtd 守护程序时，我无法连接。但是，当我尝试从同一台 Mac 上运行 Ubuntu 的 VMware VM 连接到同一个 libvirtd 时，一切正常。这是我从 Mac OS 上的 virt-manager 收到的错误消息：
Unable to connect to libvirt.
An error occurred, but the cause is unknown
Verify that the 'libvirtd' daemon is running

答案1
值得一提的是，我最终找到了 Billygoat32 在 github 上发布的一个解决方法：
有趣的是...尝试通过 UI 添加主机时出现上述错误。使用此命令可以添加它并可用于将来的连接：
virt-manager -c 'qemu+ssh://user@libvirthost/system?socket=/var/run/libvirt/libvirt-sock'
