我无法Fedora-Live-Workstation-x86_64-23-10.iso使用 Linux Mint 17.2 上的 virt-manager 安装到 QEMU 虚拟机中。我已验证 ISO 上的 SHA256 校验和是正确的。我可以毫无困难地安装位于同一文件夹中的 Debian ISO，并且我已经运行 Debian 7 和 Windows 7 VM 几个月了，没有任何问题。我收到的错误是：
Unable to complete install: 'internal error: process exited while connecting to monitor: qemu-system-x86_64: -chardev socket,id=charchannel0,path=/var/lib/libvirt/qemu/channel/target/fedora23.org.qemu.guest_agent.0,server,nowait: Failed to bind socket: No such file or directory

我不知道这是否重要，但在 virt-manager 屏幕上显示“根据安装介质自动检测操作系统，作为选项提供的最新版本的 Fedora 是 Fedora 20”。有人能给我指出正确的方向，以便我可以安装它吗？我很乐意提供任何所需的额外信息。谢谢。

Pat 的链接提供了修复。这显然是 libvirt 中的回归问题。正如 launchpad 线程中所建议的，运行mkdir -p /var/lib/libvirt/qemu/channel/target/（后跟chown -R libvirt-qemu:kvm qemu/channel/）解决了该问题。谢谢 pat。
