在 Xen 上使用 virt-manager 创建虚拟机时出错

经过一番努力，我终于安装好了 XEN，现在我正在使用 virt-manager 并尝试创建虚拟机。由于我的硬件不支持使用网络半虚拟化安装进行完全虚拟化。在我指定所有详细信息（如 URL、N/w 等）后，我收到以下错误：

Unable to complete install: 'POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: 'NoneType' object has no attribute 'rfind'")

这完全错误：

Unable to complete install: 'POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: 'NoneType' object has no attribute 'rfind'")'

DETAILS->
Unable to complete install '<class 'libvirt.libvirtError'> POST operation failed: xend_post: error from xen daemon: (xend.err "Error creating domain: 'NoneType' object has no attribute 'rfind'")

一些旧版本的 libvirtd 因一些内部错误而变得混乱，并开始抛出此类错误。我从未费心去追踪确切的错误，因为它最终在多次更新后得到了修复。

要做两件事：

  • 要使一切恢复正常，请重新启动 libvirtd。（这不会影响正在运行的虚拟机。）
  • 确保 libvirtd 是最新的。
