Libvirt Ubuntu安装HVM问题

Question

因此，我一直在尝试使用virt-install启动Ubuntu服务器安装，但我似乎无法使其正常工作。它会失败，并显示以下消息：

ERROR    Couldn't find hvm kernel for Ubuntu tree.

我在论坛上到处看到关于这个问题的帖子，但所有的帖子似乎都说这个问题已经在我目前使用的1.5.1版本中得到了解决：

$ virt-install --version 
1.5.1

在使用下面的--debug时，我已经包含了输出：

    $ virt-install --name u001 --ram 2048 --disk path=/srv/virt/ubuntu_u001.img,size=20 --hvm --debug --vcpus 2 --os-type linux --os-variant ubuntu18.04 --network bridge=virt0 --graphics none --console pty,target_type=serial --location '/mnt/ubu' --extra-args 'console=ttyS0,115200n8 serial'

作为参考，主机正在运行Arch。有什么想法吗？

我也遇到过类似的问题。尝试使用其他iso镜像。我把ubuntu-18.04.1-live-server-amd64.iso换成了ubuntu-18.04.1-server-amd64.iso (你可以从这个网站下载：http://cdimage.ubuntu.com/releases/18.04/release/ )，一切正常。
