所以我一直在尝试使用 virt-install 启动 Ubuntu 服务器安装，但我似乎无法让它工作。它失败并显示以下消息：
ERROR Couldn't find hvm kernel for Ubuntu tree.
我已经看到关于这个问题的论坛帖子，但所有这些帖子似乎都说这个问题已在我目前正在使用的 1.5.1 版中修复：
$ virt-install --version
1.5.1
我在下面使用 --debug 时包含了输出：

作为参考，主机正在运行 Arch。 有什么想法吗？
我也有类似的问题。尝试使用其他 iso 映像。我将 ubuntu-18.04.1-live-server-amd64.iso 替换为 ubuntu-18.04.1-server-amd64.iso(您可以从此站点下载：http://cdimage.ubuntu.com/releases/18.04/release/(，一切都可以正常进行。
